Another thing you can do is store both page "renders" as well as database results in http://memcached.org/ blobs and pull from those in intelligent ways (you can creatively mix and match "live" stuff with cached stuff and you can make pages expire in defined hours via your cache class or even a crontab). We also add another layer in that if a blob exists in the memecached but not locally, we save it locally for the next hit. Depending on your hardware though the Gigabit/Fiber might be faster access than a local HD/SSD/RAM disk, so YMMV. We use LAMP and our site gets > 30,000 hits per SECOND on two servers and 5 pools. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
