Processor affinity isn't nearly as complex as threading; it means to set up a system whereby certain processes run on a particular processor set; e.g., all httpd processes run on CPU set 1, all image processing tasks run on CPU set 2. That way CPU set 1 can continue servicing httpd requests without being bogged down by the CPU intensive tasks running on CPU set 2. If pset is available as a command on your multiple CPU machine then you can probably set up processor affinity. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
