Switching to InonDB may help you here, since all tables are stored in just a few tablespace files and the table cache is unused. Also, the table cache is just a linked list, so if you're thinking about rebuilding mysql with a higher hard table_cache limit, consider whether you want it to be scanning a 50k-element list every time it needs a table :) 16384 is probably too high as it stands. -- Dan Nelson [EMAIL PROTECTED] -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
