IDS 11.7 Tuning help

We have recently migrated from IDS 11.5 to IDS11.70 FC5 instance running on Linux. We have one application that makes many separate connections to the database. They connect, run small queries and disconnect. The queries usually take less than one second, so these connections come and go very quickly and there are alot of them. We are experiencing some slowness on the 11.7 server that we did not see on 11.5, so I'm looking for help getting this new server tuned up. The only think I know to look at is NETTYPE params 11.5 - NETTYPE soctcp, 50, 100, NET - when I start this engine I get this error: Warning: Number of poll threads for nettype soctcp has already reached the maximum of 50 11.7 - NETTYPE soctcp, 40, 100, NET Thanks in advance!
