I'm staging a remote office setup using vlans on gigabit switches with a Kerio VPN tunnel between kerio control appiances, and I'm seeing odd speed differences. Using iperf -r between linux computers, one on each side of the VPN, I get these speeds

Server listening on TCP port 5001
TCP window size: 85.3 KByte (default)
[  5] local port 5001 connected with port 52028
[  5]  0.0-10.0 sec   112 MBytes  93.7 Mbits/sec
Client connecting to, TCP port 5001
TCP window size: 99.0 KByte (default)
[  5] local port 48409 connected with port 5001
[  5]  0.0-10.2 sec  11.8 MBytes  9.63 Mbits/sec

I'm not surprized that it's far less than gigE, but that it's different in one direction than another, and that one direction is basically throttled at 10Mbit and the other 100Mbit, which makes me think it's something articial. I have nothing on the QoS section on either kerio appiance.

what can i try? I'm not yet sure what my bandwidth at the remote location will be, but >10Mbit is very likely so i'd like to see better performance on this with gigE before shipping it.
