I'm wondering if anybody is able to provide me with any guidelines on how to configure the buckets. Is there a relationship between the maxproc setting and the number of CPUs available on the host for instance?
The ideal setting depends on a number of factors. If the server is used for anything else in addition to serving tiles, you'd probably want the maxproc setting in the highest priority class to be a little lower than the number of cores, so you still have a "spare core" to do other things even if the server is under full load rendering tiles.
The lower priority classes depend on what mechanism you want to use to update your tiles. I don't normally bother doing tile expiry; I just have a cronjob running that stuffs the oldes 10k tiles into the queue for re-rendering once per hour. This means that my low-priority queue is *always* full, so tirex will *always* keep "maxproc" CPUs of the lowest priority queue busy. This means that I don't usually set that to anything more than 4 even on a 16-core machine.
