I've been comparing the performance of 4.1 with the MySQL 3.23.58 that came with our Rocks cluster software.
I'm finding that 4.1 is running approximately 1/3 slower (e.g. a 0.075 second query goes to 0.100 seconds) than 3.23.58. Size of buffers, etc. seems to have little effect. The database is fairly large with about 3 gig spread over a half-dozen tables. The largest table has 62 million rows. Is this other's experience? If so, should we expect that after a production version of 4.1 is released? --Thomas Hickey, Chief Scientist, OCLC --614.764.6000 --mailto:[EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> --http://errol.oclc.org/laf/n82-54463.html <http://errol.oclc.org/laf/n82-54463.html>
