The usual tuning parameter is the TCP buffer size. Linux is tuned for a 10Mbps LAN, and in Australia that's regularly too small (as although the speed is 1/20th the distance is much more than 20 *).
If you look at notes from my Web100 presentation http://www.linuxsa.org.au/meetings/ you'll be able to calculate the "bandwidth delay product" and allocate enough buffers. Make sure you are running timestamps. Some silly people turn these off to save space in the packet but on real Australia-US circuits you always win by having a better estimate of round-trip time. -- Glen Turner Tel: (08) 8303 3936 or +61 8 8303 3936 Network Engineer Email: [EMAIL PROTECTED] Australian Academic & Research Network www.aarnet.edu.au -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
