From af7b2d61c0c7f9b4fe53d8f5d18b5426a93cbd7b Mon Sep 17 00:00:00 2001 From: Joey Hess Date: Sun, 27 Mar 2016 22:10:48 -0400 Subject: add dep on concurrent-output, and re-enable -O0 Using the external concurrent-output library lets it be built with -O2 as is needed to get good runtime memory use. Enabling -O0 because ghc is using rather a lot more time and memory due to the new more complex types. old master branch: Linking dist/build/propellor-config/propellor-config ... 24.59user 0.97system 0:25.93elapsed 98%CPU (0avgtext+0avgdata 354612maxresident)k 1544inputs+46064outputs (0major+371244minor)pagefaults 0swaps this branch before -O0: Linking dist/build/propellor-config/propellor-config ... 25.56user 0.73system 0:26.61elapsed 98%CPU (0avgtext+0avgdata 345348maxresident)k 0inputs+43480outputs (0major+364163minor)pagefaults 0swaps this branch with -O0: Linking dist/build/propellor-config/propellor-config ... 11.91user 0.75system 0:12.97elapsed 97%CPU (0avgtext+0avgdata 237472maxresident)k 16inputs+37264outputs (0major+336166minor)pagefaults 0swaps Above benchmarks are building all source files needed by config-simple.hs.
