You working round what I just said.  A nic should perform equally well
as it does in other operating systems just because its cheaper its not
an excuse for buggy performance.  There is also other good network
cards apart from intel pro 1000.  I am talking about stability not
performance, I expect a intel pro 1000 to outperform a realtek however
I expect both to be stable in terms of connectivity.  I expect a
realtek in freebsd to perform as well as a realtek in windows and
linux. :)

We have our own opinions but for many tasks a vr re bge etc. even a rl
does the job its required just fine.  I have seen linux servers using
rl adaptors outperform freebsd servers with superior cards because the
linux driver is better.  I do agree its a sad state of affairs
datacentres like to rent out servers built from desktop parts but
unfurtenatly thats the market for you unless paying a premium or going
with own hardware colocated.
