Hi everyone

Looking for some help with a small problem I have.

I have a linux server (RH9) that also has a dual boot with Windoze. I am using a Vigor 2600 router with a 512 adsl connection.

The problem I have is to do with speed. Whan I boot into windows I get speeds of 472, using an MTU of 1458 and RWIN of 12500. No problem. Testing against dslreports-tweaks give no issues

However when I boot into linux I only get speeds of 450. When I test on tweaks, I get frequent stall messages and also get lots of re-transmitts, which is probably why the speed is down. I know that linux is supposed to set the RWIN value itself. (MTU 1458)

I am using the same hardware under the same circumstances.

What I would like is any advise, suggestions,tweaks, test etc. I have looked at the ip setting in /proc/sys/net/core but seem to have no effect (am i changing the correct files).

Pulling my hair out now

Thanks

Would really like some advance help on this?

In rc.local, enter these commands with the right rwin and mtu values. Restart the network. That may help.

echo 7300 > /proc/sys/net/core/rmem_default
echo 7300 > /proc/sys/net/core/rmem_max
echo 64 > /proc/sys/net/ipv4/ip_default_ttl
echo 0 > /proc/sys/net/ipv4/tcp_timestamps
echo 1 > /proc/sys/net/ipv4/tcp_sack
echo 1 > /proc/sys/net/ipv4/tcp_window_scaling
ifconfig eth0 mtu 1500

Good Luck,
Ted.
