What is the performance difference between running a regular glibc under
Xen vs. this special one? I believe there may still be some value in
running Fedora in a Xen i686 guest VM.


I would like to get an idea of who is running Fedora in an Xen i686 guest with this binary? We have a lot of "I believe" but very little data on actual usage.
