If its still slower, try using FAST_IPSEC instead on the

That increased it to 39mbits/sec. Still far from 54mbits/sec
Are all of the TCP params (compare sysctl -a net.inet.tcp on both
)and application defaults still the same on both systems ? One that
that for sure is not in RELENG_4 is SACK. Try disabling that and see
if there is a difference.

I checked the sysctl's between the two system and where the match they
are the same. The raw transfer rate ~94mbits/sec is the same as I was
getting between the systems when they were both 4.9. The real
difference appears to be in ipsec. The other thing that is interesting
is the idle time when I am running this test on the 6.x system is about
70% when it was a 4.9 system getting 54mbits/sec the idle time was only
50-55%.
I am reluctant to try fast ipsec because of problems I had when I tried
it under 4.9, it didn't work with our existing sites.
