My server runs slow but it's ok of memory

which parameters might I check?

Hi.

My server is hosted within a Virtuozzo VPS Server, and it runs very slow. Sometimes, when I type commands via shell, it takes 1-2 seconds to be echoed.

I've just checked free memory ('free -m') and it seems to be ok:

free -m
       total    used    free   shared  buffers   cached
Mem:     8104    7642    461     0    220    3979
-/+ buffers/cache:    3443    4661
Swap:     4094     0    4094

If I check "ps -ef" I don't see any weird process and with "top" the most memory-wasting process is 'mysqld' (0.8%).

Which extra parameters might I check? Thank you very much.

that to me sounds like a network connection lag between the terminal(you) and the server. rather than any memory problem with your server....
