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've got a VPS which is serving as the main server for a number of sites. Web Server, SSH Server, and Mail Server.
What I've got running:
Apache2, PHP5, MySQL5, Dovecot, Postfix
One of the sites is a growing forum with a MASSIVE photo album. This is the site where I notice the most slowness.
Changing the server software is not an option - Only optimization.

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?

View 2 Replies View RelatedIs anyone running cPanel within a guest linux distro on a VMware ESX host?
I am considering converting some cPanel boxes to VM guests mainly for redundancy. Each host would only run a single VM guest (200 GB VM disk). I am only looking to do this so that if hardware dies I can bring the VM up on another host (shared storage).
I need performance to be good though... a long time ago I tried doing it on VMware 1.x server and it was awful. I would hope with ESX, performance of the VM guest would be much better?
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.
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 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?
Does anyone here use VMware server on a dedicated server to run Windows or other OS? And in terms of IP address how would this work? Do you need to set the VM as being NATed, or does it have it's own external IP? In terms of performance on a typical 100$-200$/mo dedicated server, how good is it? All these factors depend on a lot of things and I realize that, though. (what apps run, etc)
And do server providers even allow to install something like this? I've never leased a dedicated server before but I'm thinking of getting a linux one, but also running a windows VM for a RunUO server, and unfortunately that only runs in windows. I want a linux server as I prefer LAMP for hosting, and I'd try to get a few clients on the server just so I can pay it off monthly. Also Linux servers are generally cheaper monthly and I like the idea of using SSH tunnels rather then straight RDP, which gives me chills just thinking of, from a security perspective.
Recently, I installed VMWare Server 1.0.4 on my dedicated server.
When I tried to install my private IP on my VMWare, I had no clue how to do that. I used NAT networking to share my main OS with my private VPS, but when I try to run a service that needs the port XXXX to be open, it wouldent let me use it.
For an example, my main OS IP is 82.00.000.000. My VPS is sharing the same IP address with the main OS. I tried to run an Apache service on my VPS, but when I try to access it by the IP 82.00.000.000 it gives me a connection reset page.
This also happens on other services like FTP and stuff.
My VPS is running Windows XP Professional SP2 with a legal retail license and my main OS on the server is CentOS 4.5

I am just trying the water with VMware as a virtual platform to give some friends some freedom in hosting and cut down on the cpanel cost with vps
I installed vmware on my centos5 distribution, and used the default values vmnet0 is bridged to eth0.
I have multiple ips to the host server eth0 to eth0:7 i think, how do i create a bridge or assign an ip only for that one vps to use.
create another bridge for eth0:7? then manually enter the ip info in the guest and bam?
Has anyone every done this before? There are so many better bargains out there for *nix based machines. We'd like to use some of these to host VMWare Server and then run one of our windows images on it.

I have configured and install VMWare Server on my server and currently trying to install Plesk. I have gotten the network working so I can download.
I want to give the VMWare Virtual Machine it's own IP so I can connect via PuTTY instead of the console, which e.g. does not let me paste url's (plesk download url is long).
I am planning to host a few websites on the Plesk Virtual Machine. I have added the IP my network provider given me using 'setup' in CentOS and it's listed in /sbin/ifconfig, but does not work yet.
Do I first need to add the ip to the host server self? Or can a VPS directly use an ip?
(PS: Do I use too many hard breaks in my texts?)
I have Windows Server storage server. However I need to run some Linux scripts. Is it possible to run possibly VMWARE to have Linux so I can install the scripts use the Windows which has content to be used.
Kinda tricky I know but worth a shot.
Windows - Has all the content , but can't run scripts such as file hosting , streaming server (WMV wont do) , HTML/PHP server scripts.
I installed VMWare Server 1.0.4 on my dedicated server, and set-up a new Windows XP Professional VM.
I have 3 more IP's that are not used.
When installing the VM, I used NAT networking to share my main OS network with my private VPS, but basically no one can access the VM from the outside world. I can surf the net while being on NAT status in the VM, but if I try to run any service like Apache, no one can enter to the service besides the localhost.
My VPS is running Windows XP Professional SP2 with a legal retail license and my main OS on the server is CentOS 4.5 (detailed hardware is mentioned below)
Do you have any idea how can I configure my network so anyone can enter the VPS?
And please, if you can explain me step by step because I'm a real newbie hehe

Using CentOS 4.5
I yesterday installed VMware Server under Windows Server 2003 x64, Enterprise Edition, and have this morning noticed the message 'Service unavailable' when browsing to a website hosted on the server under IIS. I have briefly looked into the problem and found the DefaultAppPool stopped, but after restarting it, it resets back to the stopped state when I once again browse to a hosted website.
Does anyone have any experience of this problem and a workaround?
Many people have some problems with vmware server on some 64bit operation systems.
If your server's ram is more than 6GB, you have to have a 64bit OS but I have tried to install vmware server on a 64bit server, it seems to be crashing my vmware server every 5 min and I cant use it more until I reset this service.
CPU : Intel Xeon Nehalem 3440 2.53Ghz Quad Core w/ HyperThreading (8 virtual cores)
Ram : 4 GB DDR2
Os : CentOS 64bit
I have had an another server and i have solved this problem whit Debian. but on CentOS I usually have problem, and I cant use vmware server.
Have you any idea how i solve this problem on CentOS 64bit?
Our company website runs on a Win 2003 server with ASP.
Now we also want to run some new PHP applications (e.g. MediaWiki). I think of running them in a (Linux) virtual machine on the Win 2003 server, to keep everything separated.
Does anybody else use VMware to split his dedicated server in several parts? It sounds like a good idea to me, but can not find much information about it. Or are there better alternatives?
I am using dreamhost host 3 of my web sites and 1 blog. Dreamhost is great, offers alot space and bandwidth.
but I think they are oversellling their space, sometimes it gets really slow. (overselling ? ok, I dont really know, but sometimes its really slow, and most my asian readers said need to refresh to load the page. I am wondering if theres a way to check if they are overselling or not.)
I am thinking about buying vps, even tho, I still got 5 month left with dreamhost.
I found 2 vps companies are highly recommanded on this forum, JaguarPC and LiquidWeb.
theres already a post compared both companies in terms of price and service. I say I will pick JagarPc, cuz, its basic plan just 20 USD, and htey got promotion now, its even cheaper. and basic Liquidweb vps plan is 60 bucks.
I am wondering why Jagarpc is so cheap , are they overselling? how can we check if they are overselling.
I found a few posts saying how good jaguarPc is. and they are not overselling, but those members just signed up this month, and only have 1-3 posts. I cannot really trust those new members.
Can someone share their experience with JaguarPC? compare JaguarPc performance and liquidweb performance. antoher question is switch from dreamhost to JaguarPC basic vPS plan, will performance gets better?
last question: VPS account allows 3 IP, 3ip = 3 domains? if not, how many domains can I have?
We are getting into VPS hosting and wanted to get some opinions and feedback as we're quite unsure on what to expect as for performance and how many clients we can generally keep on a box.
For now we've bought 3 dell R710 with dual Xeon L5520, 72GB ram and 8 x 2.5" SAS drives.
We are thinking of a base offering of 512 megabytes of ram and
was hoping to get about 40-50 onto a server.
With 40 there should be -plenty- free ram and plenty drivecache.
Then a next offering of 1 gig ram and next one of 2 gigs.
Even if we do the biggest 2 gig offering with 25 on a server we should have free ram to spare.
The software would be virtuozzo.
Any thoughts on this, am I expecting too much, or am I being fairly realistic?
Hi"Optimization of computing resources has long been an important management issue. One of its aspects concerns server scalability and the question of whether an organization should scale-up or scale out.Assume that the computing performance of the servers can be measured by variable 0 <=p, that their total cost is given by "c" and the relationship between server performance and cost is defined by c=αp^β"
a. What is the cost-performance elasticity(ђ), precisely?
b. What would be the range of values for ђ that would be expected by moore's law and what are its implications?
c. What would be the range of values for ђ that would lead managers to scale-out? Draw a graph and throughly explain the implications.
We are a web-based Yacht Charter company, with offices scattered around the world:
www.boatbookings.com
Currently, both our web site and our back-office business management system are hosted on a single server in the UK, with an automatic fail-over to a server in Dallas, TX, USA.
The problem we are having is that our sales office in Singapore is having really slow response times and this is very frustrating for them.
Using an application called "JustPing" we see that response times From Singapore are much slower than other parts of the world. (the cities closer to London are fastest, the ones further away are slowest)
JustPing Results
Is there anyway to improve this or is hosting our applications on multiple servers the only way to improve performance. What's the best cost-effective method of multiple server hosting?
(Incidentally, if I JutPing Google, response times are fantastic worldwide, but we know they're hosted on many, very large servers)
I was just playing around with litespeed and I thought I would switch back to apache for a few min to see how the server reacts. The load with litespeed was 1.00 - 3.00. I switched to apache the load jumped to 28.00 - 35.00. Its amazing how litespeed is handling connections.

Another thing is Paessler software which can test exactly what I want (number of visitors for some period of time with full page download) but it must be run from one (my) PC, so I can not test bandwidth from multiple locations.

View 5 Replies View RelatedMy dedicated server is sometimes sluggishly slow. I would like to get a grasp of its performance during a day, to get a better understanding of what's going on.
Therefore I am looking for a server performance monitoring service. All service I found so far were simply monitoring uptime (server is down / server is up). I need something more - a service that checks every 30 seconds or so the loading time of the main page.
Then it would allow me to download the data in CSV or draw a response time graph.
I've recently found (last 6 weeks) that the performance of my client's websites on my trusted host's servers isn't how it used to be and/or how it should be. The download seems to take way much longer than before. So far it hasn't resulted in a significant drop in average pageviews per unique visitor but it might do if things continue. The host claims a number of attacks on the mailserver and an unusually high load at one point in time. Above all it's just annoying - isn't reliable server performance what can be expected from a reputable host?
Here's the question: what's the best way of monitoring online how the web and mail servers are performing so that I can take this report to my host and urge them to take (more) action? Ideally I'd like to compare this with a seperate web server that I use for another client. I don't mind spending a little bit of money but high subscription fees are not in my budget.
