Thanks. No, the number of connections in my case will be small -
hundreds, and right now target servers are utilizing 4-5 Gbit/sec
bandwidth, so I'm looking forward to something more performing, thats
all. The pps number is also way below Mpps - at this time it's about 200
kpps, so I really hope I won't be facing a situation with millions of
pps, - though seems like it will be slightly above 1 Mpps. Hopefully
with the help of the community I'll be able to tune the servers to
handle this ! :)

Thanks.
Eugene.
