Lightningspeed haskell

[Simon Peyton-Jones]

Cool!  Thanks for doing this.

I guess GHC is fast because it's implementing lightweight
threads inside a single OS thread.

| Hi all.
| 
| Some days ago someone posted this url:
| http://www.bagley.org/~doug/shootout/
| 
| which is a page benchmarking a number of different languages and
| compilers where ghc is one of them. Some benchmarks lacked a haskell
| versions (and some still do) and so I decided to fill in some 
| of the gaps.
| 
| One benchmark turned out to give pretty remarkable results. It's the
| producer/consumer benchmark. I suggest you all take a look at it. The
| haskell version is six (SIX!!!) times faster than the c version. Hey,
| what's going on here? I would really like to hear some 
| comments from our
| dear implementors.
| 
| It should be noted that synchronisation is achieved by using
| slightly different kinds of primitives. But still... six times...
| 
| I lift my hat of for the ghc-implementors.
