More fun with Haskell-in-the-large: linking time has become the main bottleneck in our development cycle. The standard solution would be to use an incremental linker, but it seems that gnu does not yet support this:-|
Hmm, I've never heard of linking being a bottleneck.
The runtime loader stuff I'm working on[1] takes around 10 seconds to compile ... and 3 minutes to link it with libHSbase and libHSrts. (This is on a 500MHz PIII). Linking is a huge bottleneck once you start linking in the Haskell libraries; ld takes up enormous amounts of CPU time resolving symbols, I think.

3 minutes???!! I just downloaded your example code, did './configure && make' and the link step took about 3 seconds. This is also on a 500MHz PIII. Are you sure you're not getting libHSbase over NFS? There may be something that ld is doing that causes a lot of NFS traffic. Cheers, Simon
