Server load problem....is mysql?

[joximu]

ok, so log-bin was already off (I had a message to also comment the other lines - but maybe it's not neccesarry).
Hm - so, the other approach is: log the "slow" queries.

log_slow_queries = /var/log/mysql/mysql-slow.log
long_query_time = 2

and maybe:
log-queries-not-using-indexes

This can help find the scripts that should be optimized...

You also can have a look in phpMyAdmin, Status... there are also some interesting numbers...
