Aki Sukegawa resolved THRIFT-2236.
----------------------------------
Resolution: Fixed
Fix Version/s: 0.9.2
Resolved via THRIFT-2641
With -O1 compiler option and TestClient -n=1000, Haskell is still slower than
C++ but difference was ~60%, not 30 times anymore.
> Haskell implementation has very low performance

> See question on stackoverflow:
> http://stackoverflow.com/questions/19512952/haskell-thrift-library-300x-slower-than-c-in-performance-test/19530547
> To sum up the problem is with Haskell Thrift implementation which is 300
> times slower than C++ on small operations and 30 times slower on bigger ones.
> We have discussed this issue on haskell IRC and stackoverflow and as someone
> has noticed, that one of the problems is with wrong implementation, which
> reads 4 bytes of the stream and handles the rest of it in a lazy manner, see:
