Hi all, I've upgraded my DSL to a FTTP connection (Verizon)
I have the 15m/2m package.
However pfSense seems to preform very slowly with it. My speed tests using pfSense is around 3m/768k. Now when I use the ghetto Verizon router I get around full speed (13m/1.5m est.)
I've modified several sysctl settings to configure it to values either verizon recommends or dslreports users recommend.
MTU is 1492
I have now set in /etc/sysctl.conf
kern.ipc.maxsockbuf=653400
net.inet.tcp.recvspace=522720
net.inet.tcp.sendspace=130680
net.inet.tcp.rfc1323=1
and set kern.ipc.nmbclusters="16384" in /boot/loader.conf
This should be correct for my speed.

I'm still not seeing the speed I should be though.. hmm ??
How do I set the Unscaled RWIN value?
