just for my own info.. what did you do to drop your
retrans rate from 37% to single digits?

break with less than 0.5% retransmission rate, and others do fine with
up to 3% packet loss (meaning packets will be retransmitted.) It also
depends on whether your users are complaining or not.

I am very grateful for the reply. I'm looking on the inside of a
firewall between a device that acts as a gateway for mobile devices
connected to the Internet for GSM/GPRS.
Mobile Devices <-> GGSN <..trace here..> Firewall <-> Internet
I'm seeing anywhere from 4%-7% retransmission down from 37% ... I still
want to clean this up, but wanted to get "ideal" and "real world"
numbers before setting my goals.
Cheers,
Sean
