I have so far found out that directing some of RAM into MailScanner via child process will give lower CPU usage and therefore lower load. (one child uses 20M)

I only have about 20% RAM in use from 32GB.. wondering if MySQL can get anything good from it or other parts of server.

How and where can I direct more RAM so server would have less load in CPU and lower load?
So it would become more stable.

Server is used for domains, apache, mail, MySQL

Hello :)

You can also ensure the following option is turned off under the "System" tab in "WHM Home » Server Configuration » Tweak Settings":

"Conserve memory"

Thank you.

1. You can use high caching settings for mysql, this is rather useful.
2. /tmp in memory
3. optimize php for high load.
4. higher mysql connection count.


Keep about 40% or more free, the memory amount will change when busy, not to mention linux has caching build in <-- which people tend to forget.
