> TNonblockingServer creates two packets for each result: size of result and result data. 
> On a default FreeBSD (both 6.3 and 7.0) installation it causes a 100 ms slowdown (it tries to pack an ACK packet with a next packet, but the program waits for new input).
>  
> Attached patch merges these two packets into a single packet.
> Here is the result. The svn version serves on 9090 port and the patched version on 9091:
> $ python qx.py 9090 > /dev/null
> time is 0.104
> $ python qx.py 9091 > /dev/null
> time is 0.006
> I think high loaded thrift server can get some speed up even if it works on linux.
