no, not at all - it's not surprising that something with a chipset from 2 
years ago will spank it.  The 6500 is a great GE aggregator switch, but 
only a mediocre 10G platform.  Retro-fitting high density 10G on a 
backplane dating from the early 2000s is not really a viable option if you 
actually need to push lots of data through it, so it's not surprising that 
it's no good for HPC.

If you can live within their limitations, the current generation of 10G 
top-of-rack switches provide ridiculously good value.
