Testing innodb (9 replies)

I am trying to test different schema against each other in Mysql Innodb. However, it is hard to have reliable results as the second query will benefits of the index already loaded. Of course, I like to test scenario where the index is already loaded, but I would like to test worst case scenario where the day to day transaction could conflict with some report building.

I already made tests with partitioning and could not find a scenario where partitioning was better, so I suspect that if my index need to be reloaded, it would win the battle.

Yes, I already use SQL_NO_CACHE.
