For the finer points of performance measurement I defer to Rob. This is a highlevel coarse view: With a VSWITCH with LACP involved and using two full IFL's with 4 OSA GbE I could barely exceed 100 MB/s with no other activity at all. With the same 2 IFL's and 4 OSA dedicated and bonded within Linux I have seen 175 MB/s with other activity going on.
