I think he means the sync (or was it flush? in any case, the io performance sinkhole) on every read/write bug of 1.3, which would explain the really awful performance (since a lot of the test consists of writing out characters). The gc is also involved with the grossness (do a gc-stats after interrupting and behold the horrid numbers). It runs pretty swiftly with the gc disabled ;) -- Greg: this is exactly why a new release should've been made right away with the io problem fixed... ahh, reveling in itoldjaso ;)
