Ok here we go,
- Intel Core2 Quad Q8200
- 2GB Memory
- 2x 250GB 7200rpm Hard Disk
- CentOS 5.4
- cPanel Inc cPanel
- 5 TB Bandwidth
Using Apache/php/mysql/ftpd and all the rest of it..
The site hosts various frameworks, WordPress, vBulletin, Invision Powerboard, Cube Cart, Open Cart, OSCommerce, LemonstandApp, custom apps
I have about 30 accounts, most of them quiet, one of them really busy.
Biggest DB is the vBulletin forum with over 30k members, 55k hits/month, 3 million posts. site is quiet these days though.
I seem to have more issues with WordPress than anything else, it's a big target for spammers and if we get hit then i'll get a server load email saying it's too high, at one point i think we were being targetted by bots as it seemed to happen at the same time every night, 3/4am in the morning when really the server should be extremely quiet at that time.
The guy who looks after it has already disabled stats and lots of other non-essential tasks as it was making the server bork.
Last server load email:
1 Min Load Avg: 54.69
5 Min Load Avg: 12.96
15 Min Load Avg: 4.55

This is pretty low it's likely to rise throughout the day.
Another problem i've noticed: I have a client who has recently transfered their website to me, it is currently in development and i'm working on it for them, i noticed some pages were hanging only for 1 or 2 seconds but it was very noticeable i thought maybe the custom CMS had some bugs or something so i went back to the old host as the website is still online there.. it was so much faster, almost instant. so i started comparing page presses between 2 different servers, exact same site.. the load times on my server were noticeably worse.
Finally, this is the spec i've been looking at upgrading to:
i3-2120 Dedicated Servers - Linux - Intel Core i3-2120
» Memory Options: 4 GB DDR3 RAM
» Hard Disk: 2 x 500 GB SATA
» Operating System: Linux CentOS 6.x
» Port Speed: Dedicated 100Mbit Port
I'm just worried going from 4 cores to 2 cores will do more damage than good? but it does have a faster core and also is a much newer processor... so i still need to know which is the better performing CPU?
Any advice is appreciated, i just want something thats robust and can handle a kicking, as soon as i experience a high load the server borks and i'm sick of worrying about it..
