Hi,
I found that the compile time of GHC 7.10 against specific packages
gets much longer than previous versions. Here is example:
https://travis-ci.org/kazu-yamamoto/iproute/builds/77427248
On my local MacBook Air, I see the same phenomena:
GHC 7.8: cabal build 8.81s user 0.94s system 103% cpu 9.430 total
GHC 7.10: cabal build 37.86s user 3.49s system 98% cpu 42.066 total
Is this known regression?
