Re: GHC build times on newer MacBook Pros?

Sounds promising. Now I just have to decide whether to get the 2.2 or 2.3 GHz version. I suspect the latter is a bit overpriced. On Tue, Aug 23, 2011 at 4:36 PM, austin seipp wrote:

I'm using a MBP with a quad core 2gHz Core i7; it has 8 overall hardware threads. GHC's build process using 'make -j9' or 'make -j12' totally saturates all my cores. I believe I can clock in a full build at well under 10 minutes (with BuildFlavor = quick in mk/build.mk.) For comparison, I also have a dual core 2gHz Core i7 (4 hardware threads) in a lenovo sitting next to it running Linux, and a full GHC build takes a bit longer. I can get real numbers later if it's actually that interesting.

I'd recommend you getting the quad-core machine, if at all possible.

Hi!

I'm looking to upgrade my laptop so that I can (among other things) compile GHC faster. I'll either get the 13" 2.7GHz dual-core Intel Core i7 model or the 15" 2.2GHz quad-core Intel Core i7 model. Anyone know if it's worth to get the 15" model? According to these benchmarks it should be quite a bit faster:

but I don't know if I can get enough parallelism out of GHC's build to use all 4 cores in the 15" model.
