better performance with 32 bit ! why?

[iharrathi.ext at orange-ftgroup.com]

The 64 bit server(server1) is faster than the 32 bit server (server2).

>Test2: OS 32 bit, bind 32 bit ==> 70000 qps server2
>Test3: OS 64 bit, bind 32 bit ==> 50000 qps server1

Get faster CPU. Or get a L3 switch and more machines behind it.

Did you try this on the same maching, or are you still using 32-bit OS 
on machine with faster CPU and 64-bit OS on slower CPU-machine?
