In that case you need a faster machine...

Reminds me of some early work on 100M ethernet where we were
evaluating the LAN monitor from 'sniffer' (not the company name,
but you know who I mean).  When we did flood Tx tests (probably from
a quad P100) it was silently dropping random packets - we didn't buy it!
