RE: [Xen-devel] [PATCH] Xenoprof patches for xen-unstable
Andrew
This is weird. Something seems wrong.
I am not familiar with the benchmark you are
running. Is this something easy to try?
If you could send me the code and some instructions on
how to use it, I can try running the same benchmark
in my environment.
I will also spend sometime looking more carefully
at xenoprof and my tests to see if I find anything wrong
