Unfortunately, as I understand things, that implies that I have to have a way to repeat the same load each time I try out new settings, so that I can fairly compare. It's difficult for me to drive the load all the way through my application, so I'm envisioning some script like pqa that analyzes the logged queries against the database during a typical load period, and then lets me replay them directly against the database with the same original frequency. Has anybody done anything similar to this? Anything better? Did it end up being a waste of time, or was it helpful? ^ permalink raw reply [nested|flat] 2+ messages in thread
