Re: [Haskell-cafe] Shootout favouring C

First of all, we recently had a thread 'Shootout favouring imperative code', and I named this one after that. I certainly did not intend to insinuate (otherwise than mockingly) that the benchmarks were intentionally chosen so as to make one particular language look good/bad. I apologize for all personal displeasure that followed. Am Dienstag, 17. Januar 2006 03:13 schrieb Isaac Gouy:

Jealousy?

I've never used C or C++ so I probably don't mix with enough of those guys to say, but the impression I got was of, shall we say, 'assertive confidence'.

Well, you asked for a _fictional_ motive, and jealousy is an excellent one. However as Brent already mentioned good old money...

and I dare say Java does suffer from that even more than GHC -snip-

then we are being unfair to Haskell by 0.002s on every test - we only show measurements to 0.01s!

And you take the average of how many runs?

See the FAQ "How did you measure…?" http://shootout.alioth.debian.org/faq.php#measure

Oh, sorry, but due to my slow and unstable connection to the net, I tend to look at fewer pages than I should (usually, after the third timed out request, I call it a day).

So I don't consider timings of such short tasks very reliable

So look at the tasks where the fastest program takes seconds and needs more than 5 lines of code :-)

And though I've no reason to suppose it would help Haskell, for the same reasons, I'd like the fannkuch benchmark changed to Pfannkuchen(10).

That's been shown for Gentoo/Intel since at least December http://shootout.alioth.debian.org/gp4/fulldata.php?test=fannkuch&p1=gcc-0&p 2=ghc-2&p3=gcc-0&p4=ghc-2

Unfortunately, often the desire for speed wrecks elegance

Contribute elegant slower programs and maybe we'll show them - we're currently showing two C++ sum-file programs, one's ~25x faster than the other.

Hm, I might. Cheers, Daniel
