P.S.: you can test it easily, doing specific queries for each case.

Hi,
In every instance I've seen, MySQL always allocates the amount you set
for key_buffer at server startup even if it never comes close to being
*used*. (It shouldn't be doing malloc()s or whatever for that on the
fly. :-)) Same thing
Hi,
I think that MyISAM uses the key buffer only if needed. The same happens
with almost all the other buffers (read buffer, sort buffer, etc.).

Nothing other than what

On a P4-2.6Ghz, 1Gb mem server of ours, mysql keeps getting slower and

Linux 2.4.20.
'top' shows that mysqld is using 264M of memory. So I presume the rest is
used for disk caching. How do I know for sure that mysql is using the rest
of the memory, or how do I get mysql to use it all?
That seems
Hmmm I would say other than upgrading your hardware try upgrading to mySQL 4.
and turn on query caching.
The difference it has made to our server is unbelivable!
We have found no problems with it so far.
