I tried it again today and it worked.
I updated to and am running SVN 2525.

Bandwidth peak (#1 to #999): 3.11048e-10 MByte/cycles
Bandwidth average: 3.10762e-10 MByte/cycles

The numbers (MByte/cycles) don't mean anything to me.
Can we report this as cycles/MB (or KB) instead? (aka Service Demand)
The other metric I care about is MB/s.

thanks,
