Processes and threads are basically the same in Linux (except threads share resources, since we're talking about the same mysql "program" is a given that these are 'threads', sorry if I'm imprecise and call everything the same). I'm no mysql expert but I highly doubt you need more than a few threads (a bunch for the db housekeeping and one per connection), looks like this server is not using pooling. Then again I don't know much about WP and I may be talking out of my behind.
