Yes, what's happening is this: GHC 6.10.2 contains some slightly bogus
heuristics about when to turn on the parallel GC, and it just so
happens that 8 processors tips it over the point where the parallel GC
is enabled for young-generation collections. In 6.10.2 the parallel

Hi
This is using GHC 6.10.2 on Windows XP, 2 processors. Is this a known
bug, or should I try and replicate it? (benchmark is fairly big and
very dependent on internal things, but I suspect the dramatic
performance slowdown is unlikely to be related to these bits).

Is it time for a parallel performance wiki, where every question that

Dear GHC team,
I withdraw my last bug report.
It was about processing a long list on a 64 bit machine оn GHC-6.10.2.
First, I cannot reproduce (?) this bug report invitation from GHC on
using +RTS -M4000m
Second, I have found that the process interruption only occurs when

Hi Guilherme,
the support for 'dotnet' FFI declarations isn't really there any longer,
having bitrotted badly and hasn't been in use for a number of years.
(I'd suggest removing the final vestiges of them from the codebase,
