10% of queries are web-based (Apache/PHP).
30% of queries are from command-line PHP scripts that get executed
(average 1/second -- they end with mysql_close() btw).
60% of queries are from command-line PHP scripts that run continuously
(in a loop, with sleep()), acting on incoming socket data.

Rene,
How are you querying the database during normal use? What kind of
applications are you using?

I know what the slow queries are--some that take 20-30 seconds to
compute, and they are normal. The number of open tables seems high,
no? The database that gets 95% of the load has ~35 tables in total.
As for cron jobs, I have a number of command-line PHP scripts that
perform regular queries. They've been running for about 10 days now.
The current high CPU state started a couple days ago.
