I've did a single ping-pong test (bouncing-message back and forth) for 
malloc and tcmalloc (linux on dual-core box) - in both cases the mean 
latency and the median latency were almost the same.

Can you elaborate a bit on what kind of testing scenario you've used for 
  measuring the latency and - possibly - what kind of hardware have you 
used?

Thanks.
