That'd be because you're probably maxing the disk system out early on and what you're seeing is a slowly-growing disk service queue? > I'm currently using COSS, but I've also tried this with ufs and diskd (with > the same results, just different times that it fails after). COSS should handle small object loads better but some have reported little benefit beyond a pair of COSS disks. Try graphing the aggregate disk and per-disk transactions/second; I bet you'll find it plateau'ing relatively quickly early on.
