KM, if you have direct access to your MySQL instance, you might want to run some checks/optimizations to make sure your tables aren't fragmented or corrupt. On my EQ2Emu server, one table is HUGE and I notice that with recent power glitches, that table gets a little buggered up - but is immediately fixed with OPTIMIZE TABLES.
Another thing, many people poo-poo, is running the command-line too "mysqltuner.pl". Just to get a glimpse if something is f'd up.
...not that I was on your preferred list :p
