I wrote [student code in Java twice the size of C code, 150 times slower]. On 12 Jul 2007, at 7:04 pm, Bulat Ziganshin wrote:
using student's work, it's easy to proof that Basic is faster than assembler (and "haskell is as fast and memory-efficient as C", citing haskell-cafe)
This completely ignores everything else I wrote. The first point is that IT WAS NOT THE STUDENT'S FAULT. The performance bottleneck was ENTIRELY in code provided by Sun. And the second point of my message, which has also been ignored, is that languages are NOT the sole determiner of productivity &c, but libraries also. My post was not about Java-the-language, but about java.io the library, and about the fact that libraries can have far more effect than anything the compiler does. So no, using the form of my argument, it is NOT possible to prove anything about Haskell -vs- C. It is ONLY possible to make claims about Haskell *libraries* -vs- C *libraries*.
