How To Improve Speeds
Jan 20, 2007
how to tune linux (currently running fedora4) server to improve download speeds for the client. I have observed that if i download from sun it is very fast compared my own server which is hosted on cogent backbone or any other.
Please take into account that both mine and other server both are at relatively same number of hops and ping time. and my server and the carrier has enough bandwidth to fill whole 100mbps, even the client is a server which is on a different backbone which can fill whole 100mbps, also guys i was able to fill whole 100mbps while downloading from sun. but when i download test file from my server it is lagging at 3mbps around. only single thread using wget command. Now what is it i need to do to get my server able to push full pipe even for single thread, ping time is 25ms. if not full at least half. let me know if you have some workaround, and server is apache no load.

Recently we ordered a few servers with soft raid1, but seems the soft raid doesn't perform well, copy a 1G file, it takes about 40 seconds.
also sometimes it takes very very long time, I haven't count it, at least a few minutes, just like the server is dead.
I have run this command.
dd if=/dev/zero of=test.bin bs=1000M count=1
1+0 records in
1+0 records out
1048576000 bytes (1.0 GB) copied, 1.14416 seconds, 916 MB/s
But obviously it takes more more than 1 second, why it shows only takes 1 second?
I'm using two ST31000528AS hard disks.

The newer Pentium 4 3.0 GHz processors had so called 'VT'-support. That's something every regular processor has nowadays.
I currently run a Pentium 4 3.0 GHz server without VT. Will there be a drastic performance boost if I use a Pentium 4 3.0 GHz with VT?
What is VT anyways? I only know that Xen requires it if you wish to host a Windows Virtual Machine on a Xen Linux Server.

I have been reading quite a bit lately about the Internap FCP. I am wondering how much it actually improves network performance and how it compares to BGP4. We currently use BGP4, but are considering using a data center with the Internap FCP for a project for a client.
I am looking for reviews from others who have experience with the Internap FCP and it's performance. How does it compare to a network using BGP4? I know that FCP uses more intelligent routing than BGP, but how big of an improvement does it make?

I have a cheap managed server and support is of little help BUT they will do what I tell them, where should I tell them to start to fix high mysql load?
The server currently has a large IPB forum, a large 4images gallery, and a couple popular Wordpress blogs, and this combo keeps taking mysql down.
What can I do server side to help this? And what shouldn't I do?

As per topic, what is the best method to do to the hardware to improve bandwidth / uplink speed of server?
I have a production server that is used for regular file serving.
P4 3.0Ghz
4GB RAM
500GB + 160GB + 160GB hard disk
2Mbps Dedicated + 10Mbps shared.
However, the most I can pulled through the whole server is always between 1.5Mbps - 3Mbps, anyway to pull the speed up to around 10Mbps should there be availability of bandwidth for me to burst?
For any informations, the hard disk is SATA 2.

Im currently running a streaming media (video) site on a p4 3.0 GHz with 2 gigs of ram. I think its a 10mpbs unmetered port. It streams extremly slow, to the point where it lags every second. It does this even though their is only 6 people on, with loads of 200 it just freezes up. What configuration would be able to hold traffic of 200 people constantly. I was on a faster server with hostgator, their dedicated pro but i went through the bandwidth in 5 days.

Just wondering really, if you have a 1U cooler like an Akasa AK-CC029-5 or Dynatron P199, do these generally run full speed 24x7 or should they be bios controlled?
I've never had any cooling issues or reliability issues with either of these coolers, but they don't seem to want to be controlled through the bios on all of the boards I have used, so they run full whack 24x7

For those of you that complain about the slow loading speed of your sites due to being on over-loaded servers or over-sold bandwidth, why do you think that the discounted rate is worth the loss of customers that you might earn if your site loaded faster.
Have you ever given your sites a try on a quality host where your site loaded faster? You might be surprised at how much more effective your marketing was when surfers stay around long enough to see your site load.
Some times in the effort to secure such a great deal and save a penny, you wind up loosing a dollar, it might not make a difference to all of you but some will be surprised at the ROI for a bit better hosting!

i am changing my hosts from hostgator to the JustHost or ImHosted.
I am trying to buy shared hosting plan. I DO NOT want a video sharing website. My website will serve around 100-150 videos of each 5 mints duration.
I am confused about speed of these hosts.
My questions are
1. How can i check the speed of these hosts (JustHost) & (ImHosted). (Any sample file download will do)
2. How can i know which of these host has the fastest data transfer rate to my country. (PAKISTAN)
3. ImHosted says it has OC-192, JustHost says it has OC-96. But how to confirm it?
I am inclined towards JustHost as they are way cheaper than ImHosted. But i am also concerned about speed. Will a OC-96 connection(JustHost) will serve a 5mint video well.?

I'm currently using ipower, which just switched to fewer but larger servers. The impact for me is a new throttle in download speed, which is about 350KB/sec (although I can do FTP downloads when logged in at 500KB/sec. Previously, with the more but smaller servers, you just got a share of what was available on the server with no throttle, and when activity was low on a server, it was enough to max out my cable's limitation of about 1.5MB/sec (12 mega-bits / second).
It seems that few web hosting sites will specify typical download speeds from a web hosting account. I'm hoping that members here could report what they are getting from various web hosting services.
My web site is
jeffareid.net
A "hobby" web site, mostly videos from car racing games, just niche market enough to not attract excessive traffic.

I just found that my VPS uses ADSL - which makes no sense since the download speed into vps isn't important, it is the upload speed. BTW, it has 100mbps port - so the port is fine, it is the network.
1. What upload speeds are available for VPS's (in mid price range)?
2. What is a reliable way to test upload speed?

Can someone who has a server with ecatel check what their download speeds are from USA?
I'm getting < 30kb/s and the port is at 20mb/s... so there should be much more speed.

I serve mp3 dj mixes for some friends and am coming up on the end of my current hosting contract here in the next couple of months. They have been a fantastic host the only reason I am working on looking elsewhere is cost-related.
I got a unbelievable deal when I signed up last year and it would run me almost $300 to renew for another year, which is out of my price range.
Aside from great uptime (99.97% over 10 months), the thing I really like about the current host is their download speed. I have a 1mb cable connection at home and consistently download files at 850ish/kbps. Everyone I have spoken with has experienced similar speeds. This is much faster than any host I have ever used and is twice as fast as another host I use.
So, what I am looking for is a host that offers something similar in that regard that's around $10/month and optimally has coupons/deals floating around.
I would be happy getting 650kbps/sec, obviously the faster the better. Uptime is always a consideration, however this is more of a hobby and I am not expecting the same uptime that I get currently.
I am not against using a dreaded 'overseller' for this venture, I just need something that pushes large files fast.
I have plenty of time to find a new host, but would like to start getting a short list put together so I can request test files and whatnot.

I've recently purchased a VPS 250P package from EuroVPS and actually signed up for a two year contract as I respect the company so much however the speeds I've got, since finishing optimising the server, surprise me.
I'm already using a VPS from another dutch company until I move everything over to EuroVPS but the difference in speeds are a little concerning to me.
Please can you guys look at these response times and tell me if they are normal?
Current VPS: Page created in 0.035 seconds with 11 queries.
EuroVPS: Page created in 0.199 seconds with 8 queries.
Both servers are using the same spec, optimisations and PHP cache however my current VPS is using Apache1/PHP5/MySQL5 and with EuroVPS I can't afford to get them to upgrade to version5 so it's running on Apache2/PHP4/MySQL4.
I did get this response from EuroVPS, does it explain the difference in times?
"...we are using enterprise kernels which are slower than standard SMP/UP kernels. The performance of our VPS instances is not as high as some competitors who are using these faster, but smaller kernels.".
Once again, I have the utmost respect for EuroVPS and love their support but would appreciate some opinions on this from you guys.

I have seen that most hosting companies will post a download link with a file for speed testing purposes. I understand that I can download this and watch the speed, etc.
What is the best way to do a download test?
For instance if I just download the file to my machine I am concerned that I am not doing a good test. I am using firefox on XP and while the download is running it shows a speed that goes up and down. I am not sure if that is a realtime number or a cumulative number based on the total download to date. If it is cumulative then I guess I would just watch the number towards the end of the download to get an idea of the speed.

I have been lurker for long time already but now decided to ask this question I have been wondering about past few months.
I rent an dedicated server from KeyWeb, with dedicated 100mbps link. The server itself isn't that good & fast, but it's just perfect for my gaming server (E4500, 2GB DDR-2 ram and 2 x 320GB sata 2 drives)
Now to the problem. Always when I download some big files with this server from ftp or html server, and if I only open one connection, speed is very poor... Like 1MB/s or so, but if I use some download manager or torrent client which opens more than just one connection, +10 or so... Then the speed is very good, sometimes it goes up to 15MB/s. The server is actually connected to 1gbps switch but I think the port is limited to 100mbps.
At speedtest (dot) net, I get results like 17mbps down and 8mbps down.
So... Is that normal or is there something wrong? I've not contacted them yet, but if this isn't normal. I will Ofcourse I'll try to solve this on my own.
and before someone asks if this ftp I'm downloading from is not fast enough... I can tell you, it's. I downloaded one big file from it at school and at max speed was about 9MB/s

I am trying to gather more information regarding Mediatemple's Nitro DPV service and also MT's network speed/connection.
Most information I see is regarding the Gridserver service which is quite poorly reviewed, but I would be quite skeptical if this census could also be applied to the higher end Nitro service? -- the Mediatemple service is running sites like Techcrunch, Mashable, etc. so I am assuming the service is better with the higher end Nitro service?
There hasn't been any reviews of the Nitro service, so still trying to get some feedback from current Nitro customers or MT Complex Hosting customers. Any here who would like to share?
As far a network speeds, the ping does seem slightly slower than some other host (according to pingdom tools), but suppossedly they are a tier 4 data center if that means anything.

Can you tell me how fast it downloads for you?
(download the 100mb file)

I am going to be having a site where users upload and view videos so i need fast streaming.
soft layer offers this
0Mbps Public / Private Port Upgrade $0.00
100Mbps Public / Private Port Upgrade $10.00
1000Mbps Public / Private Port Upgrade $20.00
Can someone breifly describe to me the difference in having more MBPS and how this would affect the performance of a site like mine and its function?
Also can someone ellaborate on these 2 and the differences between metered bandwith and unmetered. They offer 100 dollars per extra TB and then following below so im lost as to what unmetered means, because their is no way it means unlimited right?
10Mbps Unmetered Public Bandwidth $100.00
100Mpbs Unmetered Public Bandwidth $2000.00

I don't know if this is where this should go, so if the mods want to move it go ahead.
Anyway, I have been with my current dedicated server provider for around three months, I guess the transfer speeds never really bothered me because it did not affect my gameservers.
However, when I decided to start hosting big files on my webserver, the transfer speeds are around 200KB/S upload, Now I have tested this with mutiple people downloading the file at the same time, and it appears to be stable at 200kb/s although now its at 150kb/s.
So I can think of a few reasons, This connection is 100mbps and I know it should not be that slow, I figure my host could be limiting the bandwith per IP or something similar, I have emailed him and he said he did not know why I was getting such a slow download speed.
I don't know much when it comes to this aspect of computers,
My specs are:
two core-2 cpu's.
1GB Ram.
100mbps connection.
Microsoft windows 2003 standard edition.
I know the max is not 200kb/s because as I said, with mutiple people downloading the file it has remained the same. It concerns me however and I would like to be able to fix this.

I have two servers running windows 2008(rtm) and I'm getting just crappy transfer speeds between them.
server 1:
dual xeon quad core
8gb ram
dynamic mirrored disks (windows software raid, ick i know
hyper-V, 6 or so VMs, not real heavy load
server 2:
dual xeon quad core
8gb ram
3ware 9650Se raid card, raid1 (using latest engineering drivers/firmware)
The servers are connected to each other via gigabit crossover. When I start to do a file transfer (a 40gb virtual machine, through windows file sharing) it starts fast. 60+MB/s says 12minutes remain but after 5minutes and 5gb or so of transfer it's slowed way down to 7MB/s and the network usage graph that was smooth and is now choppy.

Anybody seen something like this before? We have a customer who is complaining about slow FTP speeds. At first I thought his whole connection to our server is slow (he is in the mideast, we're in the USA), but through a series of tests and screenshots I've confirmed:
1) He can download from our server via HTTP at 500KB+/sec
2) If he downloads the same file, from the same server, via FTP, it goes <1KB/sec.
I've had him try different FTP software; same result. Maybe his ISP is rate limiting FTP?
Every other customer can download fine via HTTP and FTP, and all my tests from various testing servers I have around the world show good speeds from both.

I'm the proprietor of a high-bandwidth site, and obviously, it's important to me to get the cheapest bandwidth possible. I've looked around, and it seems like European web hosts provide cheaper prices than North American hosts.
However, most of my users are in North America. Will a server in Europe be able to deliver the full available bandwidth to users in the US? If not, how much of it should I expect?

I just got a VPSlink account about a month ago and for all testing purposes, it has been great so far [my first VPS]. But I haven't transferred my main site to it yet mainly due to one specific question about download speeds. Quickly, here's what I've found about their network...
VPSLink is owned by Spry, so from all I can tell, they're using the same network speeds. Which are:
Unmetered: 1.5 megabits per sec in total traffic.
Metered: Spry's site says "throughput of up to 8Mbps"
Ok, so here's what I'm trying to find out:
I'm running a small software business with some downloads (all legal of course - they're mine ) and would like to know what the real-world download speeds that users would normally see when downloading my files. Here are the knowns:
a) Let's assume for this question that all of the user computer's are on very quick connections, so their speed wouldn't be an issue.
b) An example file would be say, 20 MB.
I'm most looking to see how speeds would be (in Kbps) if say, 20 people are downloading a 20 MB file at the same time (again, with their connections being extremely fast; fast enough for the sake of this example to not be a factor - so the max speed would only depend on my VPSlink server's connection).
I don't know of a good way to really test this since I only have access to 1 physical connection. I did try a test with a friend. Here's what happened:
I normally get about 500-600kbps sustained on my cable modem, as does my friend. When downloading a test file on my server I was able to get about that when downloading all alone. But, when my friend and I downloaded it at the same time, both of us got around 350kbps -- so the total speed about dropped in half. Again since my site is for software downloads, and when releasing an update to one of our products, sometimes I'm guessing 20+ users download simultaneously for a couple days.
This currently seems to work ok on Dreamhost, but for many other reasons, we're needing a VPS. But would this vastly decrease our file transfer download speeds to users? If users got something horrible like 2kbps, that would most certainly loose a lot of business for us since they'd just get frustrated and cancel for the most part.
Does anyone know of a rough estimate on how to figure this out, or even better, are there any VPSLink customers out there that have experience with this?
