GC should not impact general performance in such scenario but is 
likely to hinder latency which pretty much matches what you are 
observing. Can you possibly provide information about network 
layout, h/w and server code used for testing? There are lot of 
possible oversights that can make results less legible, would 
have been nice to verify those ;)
