Ok, you can do it in many different ways. As most things are cached by
OS you can do just "cat /datadir/table.* > /dev/null" or execute some
query accessing all needed data:
mysql -e "SELECT something...." > /dev/null
But it still seems that you can optimize your queries and MySQL server,
not to do such weird things.
