Hi all, i am just evaluating Haskell (GHC) for the use in the company i work. I have done some performance tests with Haskell, Java and C++ for some finance mathematical algorithms (you know, some folks are addicted to performance - not i). Unfortunately, pure Haskell did not perform very well. I then used a hybrid solution with some foreing called C code (25 lines of C) to get some boost on performance after some profiling analysis on "where is all the time gone?". I don't know exactly why, but even with the optimize flags on, the hybrid haskell solution takes six times longer than the C++ version compiled with the MS .Net 2003 C++ compiler. This one is even three times faster than the cygwin C++ compiler itself. That's what made me think: could i use the MS .Net 2003 C compiler to get the GHC libraries object code and then link them with the generated C code from GHC compiled again with the MS compiler? If it's possible, how to? Can anyone anticipate a performance improvement (like i do - well, at least i hope)? Btw, if you're interested, java (JDK 1.4.2_01 Server JVM) takes twice the time of MS .Net compiled C++ for my test. If you want, i can also post the Haskell code i tested. Regards, Andreas Schroeder
