Tim, Are you using the emulated IO drives? or internal disk storage drive. The emulated IO drives are really just an OS/2 SCSI PC type drive going thru alot of software/drivers to emulate a 3380/3390. We don't use them much because they have poor performance and high usage of them cause our OS/2 side to lockup, thus locking up the HMC. We just put developers code on them.

And my figures (input and output) are about halve of yours. So there seems to be a problem on my setup, anyone hints how to check, how to improve ?
