Performance decrease using a S-NAT Pool

Sorry my mistake about trying your snat address as source to nc test, I just intent to force BIG-IP to run with snat origin. Yes, 25 items is not a problem, I asked just because I was curious since the combination 25*65k (ip x port) is a big number to reach. So, my last question is if the SNAT pool is on the same selfip network range? Better if you share your setup (virtual server, pool, snat, etc) and maybe a tcpdump capture. Respectfully.
