Check the SELECTS you are using;  If you are using a lot of GROUP BY,
it may be a good idea to have a summary table that is updated real

With MySQL 3.22.20 you can also use DELAYED INSERTS to solve this!

Please search after DELAYED in the MySQL manual at:

By doing this, you will also find a lot of other information that may
help solve your problem!
