All very true, but when a busy website with 100 hits/interval has 25 duplicate queries, that 24% saved per interval. My only point was - when you're thinking of caching, start with what is readily available instead of re-inventing the wheel elsewhere. >> The number of connections is presumably only important if we speak >> about the number of concurrent connections.

Err yes - a query replied to out of cache will take less time to complete, therefore the connection will be given up faster, therefore less _concurrent_ connections. /Per Jessen, Zürich -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
