In the LuaJIT discussion there was some other conjecture and speculation about The Computer Language Shootout:
* John Skaller "Again, last I looked, the ranking of the languages was just rubbish. Haskell does badly, and it is indeed slow at some kinds of things, but it is very VERY good at doing others." >From which we should conclude that your comments are ill-informed and badly out of date - Haskell looks good. http://shootout.alioth.debian.org/gp4/benchmark.php?test=all&lang=all * John Skaller "Look at the results, you'll see Erlang seems slow .. yet it is used heavily in Telco applications which demand ultra high real time performance." Some confusion between "fast" and "real time"? >From the Erlang FAQ 'A hard realtime system is one which can guarantee that a certain action will always be carried out in less than a certain time. ... Many telecomms systems have less strict requirements, for instance they might require a statistical guarantee along the lines of "a database lookup takes less than 20ms in 97% of cases". Soft realtime systems, such as Erlang, let you make that sort of guarantee.' http://www.erlang.org/faq/x1079.html#SOFT-REALTIME * therandthem "Java sits in the high middle on the ranking. If Ruby and Spidermonkey are at the bottom, this seems about right." Look at spectral-norm and n-body http://shootout.alioth.debian.org/gp4/benchmark.php?test=spectralnorm&lang=all http://shootout.alioth.debian.org/gp4/benchmark.php?test=nbody&lang=all * John Skaller "At one point, Haskell was lifting loop invariants .. the test specified to do something 100 times and Haskell did it once. Is that fair and reasonable?" At one point the Shootout only used Doug Bagley's original tests. Happily, long ago, those tests were replaced by new tests without repeated calculation of the same value. http://shootout.alioth.debian.org/gp4/ * Robbert Haarman "I know from someone close to the Haskell community that Haskell is now near the top in the Shootout results, because the Haskell developers optimized ghc to score well on the Shootout." I know that the Haskell community spent several weeks cooperating on the Haskell Cafe list and wiki to develop better Haskell /programs/ for the Shootout. Better programmers, better programs, better results. Isaac Gouy __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
