if you don't use email on the server disable the service, an the anti-spam service. also if you don't need nameserver running, if you use you domain provider's nameservers disable that too..

But when it reaches around 80 % , I am experiencing slower page loads. Or has that nothing to do with each other?

And and I do not use email stuff on my server.

Reinstall CentOS 5.4 32Bit, and install cPanel.

brute force attacks?

I was thinking maybe it could be DoS attack but I forgot how to check all the connections on the servers with what IP and how many connections there are. ANd then how to ban those IPs/drop the connection from a specific IP.

Wau wrote an excellent tutorial but the site he wrote it on is no longer online. :/

also cpanel will get more than 200 mg of ram itself

plus your OS another 200 probably ... you're already on 450+ Mb of memory.
