On the machines that I have that need to talk to Windows boxes
(mail/news/web servers etc) over TCP, I put the following in the
startup scripts:
# Measures to make sure Windows boxes have throughput
# RFC 1323 "TCP Extensions for High Performance"
echo 0 > /proc/sys/net/ipv4/tcp_window_scaling
echo 0 > /proc/sys/net/ipv4/tcp_timestamps
# RFC 2018 "TCP Selective Acknowledgement Options"
echo 0 > /proc/sys/net/ipv4/tcp_sack
If I don't do this, the helpdesk gets a telephone flood of complaining
customers who cannot send mail, cannot open our webpages etc.
Mike.
