What is "normal" for mysqld memory and # processes?

Hi,

Running htop - output below on my linode (2GB RAM). It shows 24 mysqld processes running at 11.2% memory each.

Is this normal? Any suggestions for what should be changed? I am not really having any problems, but thinking this is not right.

I have APC running, no other caching (e.g. no memcached).

Also below is output of free -m.

Thanks for any advice.

Rick
