Greetings, Can you post more info on your setup, i.e - configuration of machine, etc....
I am also looking into Linux network stack tweaks. I have seen my tweaks posted for GigE, but you have to be careful. You may actually get a lower throughput. For example: sysctl -w net.ipv4.tcp_mem='8388608 8388608 8388608' This tell your kernel it can use 8388608 pages ( a page is 4K on the Intel platform) for all your TCP currently in use. so (8388608 * 4096)/1048576 = 32768MB Take a look at: http://ipsysctl-tutorial.frozentux.net/ipsysctl-tutorial.html On Fri, May 13, 2005 at 12:06:29PM -0500, Duncan, Brian M. wrote: > > Hi I was wondering if you ever got better performance out of your > Gigabit/IDE/Fc2? > > I am facing a similar situation.
