I am trying to set up a HA type system involving two identical boxes and
have gone through the following to set up the systems:
Slave server:
ggated -R 196608 -S 196608
(exporting /dev/amrd1 )
net.inet.tcp.sendspace: 65536
net.inet.tcp.recvspace: 131072
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.

I have seen sustained writes of 30Mb/s using the following configuration:
cat /boot/loader.conf
kern.ipc.nmbclusters="32768"
cat /etc/sysctl.conf
net.inet.tcp.sendspace=1048576
net.inet.tcp.recvspace=1048576
Server:
/sbin/ggated -S 1310720 -R 1310720 -a 172.31.0.18 /etc/gg.exports
Client:
/sbin/ggatec create -q 2048 -t 5 -S 1310720 -R 1310720 172.31.0.18
/dev/amrd0s2
The raid array is a RAID 1 volume on a dell PERC4 (Dell PE1850) with
adaptive read ahead and write back caching.
