I'm using the Intel driver btw, are you using the Windows default or the Intel one?
(could be significant as there is a "bug" in the MS one)
I was going to ask you to run perfmon What I notice is that the hang happens just after the loop starts. It looks very much like a TRIM operation is causing the "hang". The hang duration coincides with ~5 seconds that are recorded against the "responsetime_max-control, which I believe is TRIM related. (Hopefully overthere can confirm.) Either way the hang seems to be much more that the test files being deleted.

I'm running RST (10.5.0.1022)
