Try
net.local.stream.recvspace=65535
net.local.stream.sendspace=65535

Also, try increase this sysctls with
net.inet.tcp.rfc1323=1

I use it on FreeBSD 5.x with:
net.inet.tcp.sendspace=131072
net.inet.tcp.recvspace=131072
net.local.stream.recvspace=65535
net.local.stream.sendspace=65535

ggated -R 1048576 -S 1048576
ggatec -R 1048576 -S 1048576

WBR.
