Take a look at GHC’s performance on The Computer Language Benchmarks Game. - GHC works on several platforms including Windows, Mac, Linux, most varieties of Unix, and several different processor architectures. - GHC has extensive optimisation capabilities, including inter-module optimisation. - GHC compiles Haskell code either directly to native code or using LLVM as a back-end. GHC can also generate C code as an intermediate target for porting to new platforms. The interactive environment compiles Haskell to bytecode, and supports execution of mixed bytecode/compiled programs. - Profiling is supported, both by time/allocation and various kinds of heap profiling. - GHC comes with several libraries, and thousands more are available on Hackage.
