By latency I'm assuming you mean how long packets stick around in the
network stack before they are sent out.
Packets are small (<500bytes) and need to sent within 10ms.
Thank you for the man page pointers. They will help.

There's a lot of kernel tweaks that can be used to fine tune your
network stack for this type of workload but you didn't mention how
critical latency is to your workload. That will also need to be
factored into what settings to use.
Pretty much anything in /proc/sys/net/core/ and /proc/sys/net/ipv4/
can be tweaked and the settings can be made permanent using /etc/
sysctl.conf.
Look for the Sysctls section in the following man pages for
definitions on what each of these settings do.
man 7 tcp
man 7 udp
man 7 socket
man 7 ip

Hello,
I'm looking for advice on how best to tune Ubuntu Server 8.0.4 for
best network performance. I have a custom server application that has
up to 50,000 tcp connections open at a time.
The amount of data being sent is small -- on the order of a 3-4KB/min.
Connections come and go at a rate of 1000/minute.
Other considerations:
Disk I/O is unimportant.
Memory use is intensive.
Any thoughts?
Thanks,
Marty
