Anyone has benchmarks for vxworks 5.4 network stack on a 85xx MPC ? I
am specifically looking for MPC 8568 or 8548.

My testing shows very little throughput - 90mbps. But with a linux
kernel, processor gives really high throughpts.

Any comments/Suggestions on where to look for issues in the vxworks
stack. I was suspecting the mBuf pool running out, but seems like that
is not the case..
