Hi Sebastian,

Here are the results:

Haskell (Safe Haskell right?)

J:\dev\haskell>ghc -fglasgow-exts -O2 -o PrimeSebastian.exe

number of primes: 664579
Elapsed time: 1.375


J:\dev\test\testperf>erase primecs.exe & gmcs primecs.cs

J:\dev\test\testperf>mono primecs.exe
number of primes: 664579
elapsed time: 0,438

Microsoft .Net

J:\dev\test\testperf>erase primecs.exe & csc /nologo primecs.cs

number of primes: 664579
elapsed time: 0,390625

(I incorporated your suggestion for the innerloop, which shaved off another
20% or so in the C# classes)
