Yeah, well, during early investigation, I also used basically just
SpecJBB. See here:
http://blog.xen.org/index.php/2012/04/26/numa-and-xen-part-1-introduction/
http://blog.xen.org/index.php/2012/05/16/numa-and-xen-part-ii-scheduling-and-placement/

For benchmarking our NUMA aware scheduling solution, in Xen, I used
SpecJBB, sysbench and LMbench:
http://blog.xen.org/index.php/2012/05/16/numa-and-xen-part-ii-scheduling-and-placement/

The trickiest part is have the benchmark(s) of choice running
concurrently is a bunch of VMs on the same host. I used some hand
crafted scripts at the time, very specific to my own environment.

I'm working on abstracting that and putting together something more easy
to be shared and used outside my attic. :-P

Regards,
Dario
