Server Load Problems - Upgrade
Jun 26, 2007
I have a P4 2.8Ghz 1GB RAM dedicated server that runs one main site. The site runs vBulletin that I've extended to operate cross-site (keeping track of all members and guests) and receives around 10,000-12,000 daily unique visitors, of which the server can currently handle no more than 300-350 users online (based on a 15 minute timeout).
My top stats during CPU spikes (of which are occurring more and more frequently) indicate that the server is hitting the memory ceiling, so I need to make a decision on whether to upgrade the memory to 2GB or to purchase a new server.
Do you believe 2GB will be sufficient to solve my current load problems and maybe make room for a further 100-200 users online, or is this something that would require a better server (of which I have no idea what I would need)?

We have a quad code with 8GB ram dedicated for one website, but still the load goes through the roof and crashes the server. The site has one vB forum (with minimum hacks), and a custom CMS for the front pages which uses a minimum of queries.
I'm not an expert, but it would seem like mySQL is the one that crashes. When the site crashes and someone browse the site, you can see the "could not connect to mySQL through socket" error message. At that point the load just skyrocket (been up to 4-500), and then the server crashes and has to be rebooted.
* Is our only option to make some sort of cluster?
* Could upgrading to i.eg Apache 2.x or installing an op code cacher like xCache help?
* Is it possible to run the databases from RAM to save IO (so it only writes to the HDD on update/insert/delete etc)?
I have root access, so if you need me to run more commands to look up statistics, just let me know.

Anyone know of some good server load testers ( commercial )?
Im not looking for application based load testing, I need real web server load testing... need to see how much traffic this one site can take before it cries.

I'm having the oddest issue. For some reason, some of the websites on my server load fine, and some take a really long time to load (2 minutes).
Now, the server load is fine, and the size of the sites aren't the issue either. I've restarted Apache and a couple more services, and still the same sites seem to load very slow.
What could be causing this since it's only effecting certain websites?

I have centOS box with 1 x dual core CPU in it. The load average is between 1.5 and 3. When the traffic is on top the load average is between 2.5 - 3.5. Is it necessary to upgrade ? Server seems to be respond fast. Also I heard that Top command on centOS with dual core CPU doesn't show exact values.

I'm about to upgrade my co-locationed server from twin 2214 Opertons (dual core 2.2GHz) to
twin 2378 Opertons (quad core 2.4GHz). [Got to love the upgrade path on Opertons, single core to 6 core on the same socket.] I know I'll need to do a Bios upgrade but is there
anything else I should worry about. I want to minimize downtime as much as possible.

I have a server running cPanel.
At the moment, I am been hosted on an unmanaged server (dedicated).
My server provider is offering $25/hour for managed support.
My Kernal and Centos have not been updated for a while and I am looking to upgrade both of them. I am wondering how long would these 2 jobs normally take?

This concerns a fairly successful ecommerce website. It is coded in classic asp and has a MS SQL database.
The site sees average of 1500 visitors a day using about 50 GB of bandwidth a month.
The host wants to move the site to a two box dedicated (1 web - 1 database server).
This is an expensive proposition and the client is balking. I am not an expert in these matters but it seems like overkill to me. It seems like most sites don't have problems with the database and web server on 1 box.

How To Upgrade Apache 1.3.37 to 2.2.x on Cpanel Server?
Currently, Apache is recommending:
Quote:
Apache 1.3.37 is the current stable release of the Apache 1.3 family. We strongly recommend that users of all earlier versions, including 1.3 family release, upgrade to to the current 2.2 version as soon as possible.
1) Is it safe to upgrade from Apache 1.3.37 to 2.2.4 on a Cpanel machine. I am worried that Cpanel won't like it.
2) Is Php4 still acceptable to use with Apache 2.2?
3) Can someone suggest a tutorial or guide for an upgrade to 2.2?

I currently have
AMD X2 3400
1 GB DDR RAM
3TB Bandwidthwidth
Right now at around 150,000 to maybe over 200,000 pageviews a day thanks to an influx of Korean traffic, the number of Apache connections is making my swf files extremely slow.
I may have to upgrade the 3TB bandwidth too at some point along the line.
Its the raw number of Apache connections that is the problem, my host says. The SQL isn't causing any issues.
What do you guys suggest?
How much with a Opteron server with 2GB RAM help me right now?

I have a server running Fedora 4 and WHM/cPanel. I would like to upgrade the linux kernel to the latest version, so mosey in via SSH and type "yum -y upgrade". It downloads a few things and tells me everything is hunky dory.
Now, the version it says it is currently running is: 2.6.17-1.2142_FC4 #1 Tue Jul 11 22:41:14 EDT 2006
Is that the really the newest version available? Maybe I'm confused as to how this works, but if I go to kernel.org it tells me the most recent stable version of the kernel is 2.6.24.3. Is this because I am running FC4?

MySQL version 3.x (default with plesk).
I need MySQL version 4.0x
I have absolutely no idea how to do it.
Can someone point me to a good step-by-step guide? Or perhaps is anyone willing to upgrade it for me (I will pay, if interested, my aim is manfrincp).

I have a server with SoftLayer which is based on the Xeon 3060 with 2GB RAM and 2x250GB Hard Drives setup as soft raid using Windows 2003.
I am now looking at two options for an MS Exchange Server 2003 with 25 user licences. I can either get a new dual core AMD server with 2GB and 2x250GB hard drives in soft RAID 1 for about $170-$180 or I could bump the specifications of the current server by adding additional 2GBs (for total of 4GB), another 250GB hard drive with the 3Com RAID controller (for 500GB RAID5 setup) and possibly a quad core CPU upgrade when SL introduces it. The total cost for upgrades would total to $110. I already have a Windows 2003 server license that I can utilize.

We have one server don't want to touch the php on - how can we upgrade our PPA cluster and leave the one server alone - or at least exclude it from upgrading PHP/mySQL/Apache?

Just upgraded from Plesk 11.5 to 12. (CentOS 6.4)
Everything is working but when I reboot the server using the Plesk CP it never comes back up. No CP, no domains, no SSH.
If I reboot it using the 1&1 CP it re-boots fine.

I'm running a message board and it looks like I've outgrown the low end xeon 3040 1.86GHz dual core server, and the bulk of the CPU load is going to mysqld. I'm debating between offloading the DB to a dedicated server vs upgrading the existing server and hosting the web server and db on the same machine.
Any thoughts on the better approach? fwiw, the load from apache seems next to nothing right now, but I am also planning on adding an SMTP server for user registrations and general support email.
I'm also not super familiar with dual-core and dual processor machines. Does shifting mysql to a dual core or dual proc machine help (vs a single core/single proc machine)? since there is just one mysql daemon, does having a second core or proc. buy me anything?

I've been having trouble with my VPS for a while now. In the QoS alerts page in Virtuozzo it seems to be a problem with numtcpsock and tcprcvbuf, mainly numtcpsock.
Copy these into the browser:
i18.photobucket.com/albums/b106/gnatfish/qosnumtcpsock2.jpg
And when i run cat /proc/user_beancounters:
i18.photobucket.com/albums/b106/gnatfish/beancounters2.jpg
This line is particularly scary:
numtcpsock 164 164 166 166 7321
What do i need to do, to get the website running again? It's only one site on the vps a proxy. So i thought a vps would be able to handle one proxy.
