[SGVLUG] used memory on a 4 GB system.

[James Neff]

Thank you everyone who responded.  Your posts were very informative and 
helped me to understand Linux memory management.

To my ignorance, I had no idea what the cached and buffers were in the 
top printout, which is why I freaked out when I saw nearly all memory used.

This machine is mostly a mySQL database that will be expecting many 
(thousands per minute) small connections (not much data between client 
and database).  There are scores of articles on how to optimize the 
mySQL configuration for this sort of operation. 

Is there anything on the systems administration side I should be doing? 

I've already turned off most of the other services that
came standard (sendmail, ftp, bluetooth, X windows, etc) that I won't be 
using on this server.

Thanks again,
James
