Thanks for your response. The problem is unfortunately still not solved. Yesterday I dropped the database and re-created it from bayes_mysql.sql file that is bundled with the SpamAssassin package (and added a lastupdate field). 12 hours or so after I re-enabled bayes the load avg and I/O wait escalates again - with 5612851 tokens at the moment according to bayes_vars.
I've also adjusted the buffers according to mysqltuner's recommendations (as far as possible with the current amount of installed ram). I guess the next step is to add more RAM.
