VPS: What's using all my RAM?
I'm running a vB forum (runemart.com), and my VPS has the following specs:
~666MHz CPU
512MB RAM
CentOS 5.3 64-bit
DirectAdmin
In my VPS control panel, it's saying that I'm using around 350MB to 450MB RAM - this is 24/7, it never goes below 350MB. At the moment all I'm running is a vB forum, that doesn't have many memory consuming plugins (such as no shoutbox at the moment).
Is it normal for a vB forum to use so much RAM? Is there any way that I can find out what's using the RAM?

Just depends...The OS is probably using 100MB or so. If Apache isn't optimized then it could use 70+MB per process. This is quite possible.

Memory usage depends, But you can tweak your services to avoid abnormal use of memory.
You can use the following commands to view the memory usage
1) top -c ( Shift+M ) will sort the process by Memory Usage
2) ps auxf , will give the details of all the process that are currently running.
Also you can confirm the memory usage using " free -m "SupportExpertz.com - the name says it all!

You can make performance tweaks in Apache and Mysql configuration to reduce RAM usage considerably.
