On my development machine i'm not experiencing this at all. (i dont need to add the autocommit = 0 and i still see < 1 second performance) the production machine is a VPS, so im suspecting that disk usage may be the primary culprit and someone else has a high disk usage application. Thanks for the link. I found that if I set AutoCommit=0 before the inserts, then commit after Inserts i can cut off a lot of time. still not as fast but around 2 seconds.

Unfortunately I haven't looked into "fixing" this issue. It is known that MyISAM is faster than InnoDb, but this is the trade-off you agree to when you want to gain referential integrity and normalized data at the database layer. If this is a high availability production server I would look into some books on the subject. You can also check out some of the posts over at <a href="http://www.mysqlperformanceblog.com/" rel="nofollow">http://www.mysqlperformanceblog.com/</a>. The folks over there have lots of great stuff.
