> 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:
