Hi Serge.
We have lmbench results. We had issues getting reproducability out of dbench but need to look at it some more. The lmbench figures we presently have are from the old code (reader writer lock). Results were good but we recently converted to rcu for the reader dominated rw locks.
I'm not sure there is "0 performance hit for unconfined" as you have to check for them being unconfined :) but it's low.
If you have other benchmarks we are open to suggestions. What has been used to benchmark SELinux?
Anyways, we need to regenerate the results, we'll try and post in the next couple days. ok?
Thanks
