Ron, I was being sarcastic, but I’ve gone over the thread and I do not see any mention of the number of cores on the
server. If it has a single quad core chip then the queue for each processor could be on average 75 deep at the outset,
allof them anxiously awaiting data.  -j connections are processes, correct? Not threads. 
Atul, if you list the tools you know and have used for watching system performance and then others can perhaps suggest
alternatives(or re-interpret results)
