Not sure what Linux kernel issues have to due with a FreeBSB box, but I
am more interested in whether the following TCP settings are enabled.
RFC 2018 SACK
RFC 896 Nagle
RFC 3168 ECN
RFC 1323 Time stamping and window scaling
It is very difficult to achieve max throughput of a TCP link without at
least SACK and window scaling enabled.

We are running FreeBSD boxes w/ Gigabit Ethernet NICs
I don't know all the details, since I'm not the technical guy running the
tests, but I believe we are using "standard" 1500-byte packets w/ standard
MTUs, etc
On a 100 Mb FastE link (benchmark) we get the following
1 Way TCP Max: 94.0 Mbps
2 Way BiDirectional TCP Max: 92.7 / 92.4 Mbps
On a GiGE link, due to Linux kernal processing issues, we max out at about
400 Mbps of "raw" TCP throughput

In an attenuated lab setup, running TCP (w/ Iperf), we see the
following results with the Spectra @ the 300 Mbps data rate
1 Way TCP Max: 143 Mbps
2 Way BiDirectional TCP Max: 98.1 / 105 Mbps
What TCP settings did you use to achieve the above?
