Yes, I tried to both (either by rebuilding xen or sched=<> boot
parameter), confirming like: 
(XEN) Using scheduler: Borrowed Virtual Time (bvt)

I see the problem no matter which scheduler I choose. I think it should
be a schduling issue on x86_64 xenlinux because the cutoff over CPU
utilization is very obvious; 50% max in the top command, and top is not
confused because benchmarks run slower.
