It appears that Linux kernels are by default limited to 128 backlog entries
ch 3, 2. paragraph)

Perhaps configuring kernel differently one could increase the performance 
dramatically as going from backlog length from 5 to 100 demonstrated. I 
don't know if this applies to other operating systems as well or how one 
could make the change (by writing /proc/sys/... or by configuring and 
recompiling kernel).
