Likely as not differences in the format of floatingpoint numbers.  Sadly, 
netperf echanges floating point numbers because "way back when" there wasn't 
much support for 64-bit integers.  Fixing your problem may require changing 
netperf to move 64-bit integers around.

Short-term you can hack around the problem for the TCP tests at least - but NOT 
the UDP tests - by using the netperf side stats rather than the netserver side 
stats.

I'm going to cc this to netperf-talk because it would be useful for that to be 
in the record and perhaps it will help find someone willing and able to add the 
64-bit integer stuff to the messaging over the holidays :)
