Hmm, I remember Mark Wong from OSDL saying that it took to replay the logs after a crash more than the six hours it had taken to generate them.
Six hours? Did he have checkpoints disabled somehow?
No, I remember they were talking about recovery from backup using PITR.
(i.e. not simple crash recovery, but replaying the logs from the whole benchmark session)
