It's no problem. :-) Sorry for the late reply. Off hand, to force an index to be loaded I would say run queries that scan each index. e.g. SELECT index_col FROM table; But remember the indexes will be unloaded from the key_buffer if the table is closed -- after things like FLUSH, ALTER, OPTIMIZE, and maybe more. BTW, MySQL 4.1.1 added a new key cache system that looks like it has more tunable stuff. From http://www.mysql.com/doc/en/News-4.1.x.html "New key cache for MyISAM tables with many tunable parameters. You can have multiple key caches, preload index into caches for batches..." But I don't see anything documented about it yet. :-( > Thanks very much for your time. > > John You're welcome.
