What Can I Do To Improve Bandwidth / Uplink Speed Of Server
Oct 4, 2008
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?
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?
What are the benefits of moving to faster uplink speeds? I'm considering upgrading from 10 to 100 Mbps. Does it only mean being able to send information faster or are response times improved as well?
I recently purchased a new Dedi server, and got 100 MBPS Uplink. Now, I'm uploading 16GB size of files into this server, and I have a suspicious feeling that this upload speed is not what they told me. For the very 1st day, I opened a ticket and they said that they upgraded it to 100 mbps. I saw this speed was faster immediately. On 2nd day, it went down to around same slow speed before. Since then, I kept opening a new ticket and they said it was done, or sometimes I am under DDos attack..? What? I don't even have the site up yet! How come there is DDos attack?
Anyway, today I was told that I'm getting billed for this 100 mbps uplink, because it's a new service. What a crazy thing going on here... I am so tired of this ticket game and just don't understand why they don't commit what they told me initially.
Can anyone please tell me how I can verify and prove that I am having this 100 MBPS Uplink speed? The only thing I can tell with my eyes is that I can see those FTP upload progress bar. When it's very fast to upload one file, I assume that I have right speed.
But is there any tool or command that I can execute on the server shell, and tell them what I get as a proof?
I am curious if anyone knows what 1and1.com's uplink speed is for their shared accounts? A shared developer account get's 3TB of bandwidth. But I am wondering what type of bandwidth that is. How fast is it?
I wonder whatLs more important on a shoutcast server, to get more bandwidth per month as possible, or a faster port connection?
I have test a 2 hours music stream at 128k bit rate and was only 5MB per listener ! This is not to host 24/7 radios. Its a project to host DJs /Live Bands at a maximum of 128k, with no more than 2 hours events.
Also each event between 50-80 listeners, and not at same days or hours.
About the port connection, what this means? : Port: 10/100MBPS SWITCHED VLAN
Is it shared and from 10 to 100mbps?
I am trying to find the best deal with dedi servers. Have at this moment a unlimited bandwidth /100Mbps shared, but it seems the CPU is too low (AMD Sempron 3100), as I canLt seem to create more than 40 shoutcast accounts (and no client is streaming, just ON), and the server load goes up to 4.5 !!
So, I am looking on the market , as I saw better deals with better processors (Pentium4, Core 2 Duo), and much cheaper (below $100), but they only offer 2000/3000GB bandwidth.
My users frequently tell me that my website is slow, but it doesn't seem to be so, for me. Are there objective tools and criteria to test its speed (response time, max transfer etc)?
Also, I'm currently paying $1 for GB of transfer. How much does it usually costs?
Since my hosting company sets php_safe off, I'm considering changing it.Can you guys recommend me a hosting plan that has:
- ssh with vi etc: this is important
- A FAST server
- Norway-based (to enjoy .torrents without being bothered) or US Based (to enjoy "fair use", which seems to be exclusive to the USA)
- 1-3GB of space
- LOTS of transfer. I don't consume many gigabytes yet, but someday I will.
- Some kind of hacking protection. I'm damn scared of my website suffering a vampire attack and having to pay for the raeped bandwidth.
I currently have a windows 2003 server box which is being used only for huge file downloads (Media server). Wanted to know if there is some sorta program or script that lets me check the current connections and what speed each connection(ip) is downloading at?
I have a Cisco 4006 with a 4013 Supervisor and a 4232-L3 and 3 x 4148-RJ modules.
When downloading data from ServerA on the switch to ServerB on the switch the download speed is limited to about 650KB/sec.
ServerA -> ServerB = 650KB/sec.
ServerB -> ServerA = 11MB/sec.
So the problem is in one direction.
Each server has its own VLAN and a /29 IP block and both servers are physically connected to the 4006's 4148-RJ modules.
This seems to affect servers at random.
This issue disappears if I change the /29 IP block on the server experiencing the slow downloads while still using the same VLANs and ports to a /29 not experiencing this issue.
When I change the /29 to one that is not affected the switch is capable of full wire speed which is approximately 11MB/sec sustained. When I change back to the old /29 the downloads are limited to about 650KB/sec max.
I have tried the following:
changing VLANs
changing ports on the 4006
replaced CAT5 patch cords
replaced NICs in affected servers
replaced motherboards in affected servers
had multiple people examine the configs
and a few other crazy ideas yet the problem persists.
This problem affects only a few servers on the switch however I have a similar problem on a larger group of servers as well.
Several servers are limited to 650KB/sec downloads from very fast servers outside the network on the public internet.
For example:
LocalServerA on the 4006 with a /29 is downloading from RemoteServerA on the internet and is getting about 650KB/sec.
RemoteServerA -> RemoteServerA = 650KB/sec
LocalServerB on the 4006 with another /29 is downloading from RemoteServerA on the internet and is getting 3-8MB/sec sustained.
RemoteServerA -> LocalServerB = 3-8MB/sec
If I change the /29 on LocalServerA to a /29 which is unaffected by this issue the speed problem disappears while still using the same hardware, VLANs and physical ports.

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.
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?
What steps can we take to improve SpamAssassin performance? I know this was talked about in older Plesk versions, but we may be able to do more now. What configurations can I do to stop more spam?
We are getting trouble with a site into a dedicadte server, more specific performance issue due to many visitors on same time 1000. Mysql is overload. We would like to use xcache to improve performance, using xcache with plesk 12 centos? its safe, works fine?
I'm not much of a co-location expert as we do not own our own equipment but a customer we help from time to time is asking me about this. They have a cabinet at theplanet and only a pair of redundant 100mbit uplinks coming into their cisco 2924 they rent from theplanet. Theplanet wants $350/mo along with $350 setup for a pair of redundant gigabit uplinks. Then another $225/mo for a Cisco Catalyst 2960G.
Does this at all seem reasonable to anyone? The switch can just be purchased so it's not that big of a deal. The uplink cost cannot be avoided though. If it's not reasonable obviously they can go back to their account manager to discuss it but I don't know what you'd expect to pay in Dallas for that.
Also before anyone suggests any other provider not an option. Last time they looked around theplanet was the only provider in dallas capable of handling the attacks. Others would just null route the IP's rather than trying to mitigate the attacks. So no point in making suggestions as it's been explored in the past.
Well i need for a week some provider who can setup a spare server/vps with 1000gps uplink , to maybe convince my college to get in contract and get better providers, instead of hosting the college site on our in-house machines. Since the loading speed of site is awful ! So am thinking of trying out for only a week the machine from that provider, and if am able to convince the department to maybe get into some contract with me (who in turn will be than using that provider for getting the server).
So if anyone around wht knows someone who has spare box for a week with 1000mbps uplink would be great.
Please note, no mysql is required, just simple apache, and no traffic, just 1 or 10 hits in the entire week.
I was told that there are some companies out there that provide universities free hosting, so if anyone is aware of such company do let me know please.
Like for example, recently talked to liquidweb. They have a 100mbs uplink port on their servers, but they only let you use 30% of it. But you can upgrade at anytime. Is that normal for hosts to do that?
Does anyone know of a private Data Center with Satellite uplink/downlink connectivity in addition to Fiber?
I know the government depends on them for military purposes, but I was wondering if anyone is aware of a private, FCC liscenced data center with the capability to transmite/host data via satellite in case of disasters, remoteness etc. It seems complimentary for a data center but I haven't heard of it.
Is there any market research on this? What is a good source of information to find out about how many data centers there are, how much revenue they bring in, costs, etc? What is the data center bible?
I've two shared hosting accounts, one is hostgator and other is godaddy.
I've uploaded a file (.flv) on hostgator and same file on godaddy.
here a link to both
Hostgator flv
Goddady flv
Now i am use a Download manager " free download manager" to download files The hostgator file downloads at 17-35kb/s The godaddy file downloads at 200kb/s
I am using 2Mbps dsl.
Also my hostgator cpanel loads slow. and other files are downloads at very low max 40kb/s.
What are the issues. I've contacted hostgator support and they say that every thing is ok on their end.
I have to stream videos on hostgator but the speed is too slow. and it buffers alot.
What would be best method to test quality of server?For example,how site loads,do they load at all,speed of loading,etc.
What bothers me some of my site which i host on my servers start to lose traffic a lot lately.It could be beacuse of summer slowdown,but i simply cant belive in that.
Maybe server have a downtime or server have bad hardware router which doesnt accept all traffic.In shortly i belive something is wrong.So please tell me how do i do deep scan/check of all my servers.
