+ Where N is the max number of connections you expect to handle at one

+ bytes, say 4, if each connection just exchanges few packets. Or it
+ should be much larger, up to 1024/4096 (i.e. 1-4MB) if you have only
+ one connection and exchange a lot of packets, i.e., when you test for
+ RPS. If you need to allocate lots of FIFOs, so you test for CPS, make
+ private-segment-size something like 4g.

+ Example:
+
+ For CPS
+ test http server static prealloc-fifos 10000 fifo-size 64
+ private-segment-size 4000m
