It should work fine, but your problem is probably not caused by 
nagle.

It is probably caused by 'delayed ACK'. In bad send-receive scenario 
it causing 200ms delay. (see: your 100 send-receives * 200ms = your 
20 seconds.)

What is your communication scenario? Does you have somewhere 
something like: shortsend-shortsend-receiving sequence? (on client or 
on server...)
