RE: [reSIProcate] reSIProcate speed is much slower now
I was using the testSpeed.cxx that Andy posted from testing. I can't
remember why testSpeed was replaced by testStack - can you refresh my

Thanks,
Scott

One bit of a sanity check -
The discussion mentions testSpeed - we replaced that with testStack
quite awhile back.
testSpeed is not in the repository anymore. Was that a typo remember
things past?
