Hi Dave,

I never personally used it, but as far as I know you should be able to 
get more performance by using "gtpu-mode kernel-gtp" instead of 
"gtpu-mode tun" in your config, to avoid doing all packet processing in 
userspace. Please someone else confirm this. I think you need a capable 
kernel and libgtpnl to be able to use it.

Also, it would be nice if you could provide a linux "perf" output on 
osmo-ggsn while running your test setup so we can spot possible 
optimizations to improve osmo-ggsn performance.
