That's great news! Faster than GHC 7.8! We should advertise this :-). Simon | -----Original Message----- | From: ghc-devs [mailto:ghc-devs-bounces@haskell.org] On Behalf Of | Christopher Allen | Sent: 16 May 2017 19:09 | To: ghc-devs@haskell.org | Subject: 8.2 and earlier build times | | I did a build time test with hackage.haskell.org/package/bloodhound | today. | | I tested 8.2 (RC), 8.0, 7.10, and 7.8. I used Bloodhound in part | because it has very few but very large modules which is sort of a | pathological case for GHC right now. | | I first built the deps and library with each compilers and then reran | the build once or twice until the results stabilized. The build re- | built the V5/Types module and the examples depending on that module. I | triggered a build by adding/removing newline characters in the | V5/Types module. | | I've pushed the build targets / stack.yamls to the git repository: | https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithu | b.com%2Fbitemyapp%2Fbloodhound&data=02%7C01%7Csimonpj%40microsoft.com% | 7Cc4d32126857a47dd4dd008d49c86aa7c%7C72f988bf86f141af91ab2d7cd011db47% | 7C1%7C0%7C636305549597208612&sdata=kcqWLIARzF8xwaYwZgJ6vOkex1%2FtD53cB | %2BJlYcdnq2o%3D&reserved=0 | | | Here are the results: | | | 8.2 build: | 126.37s user 2.26s system 101% cpu 2:07.16 total | | 8.0 build: | 147.44s user 2.24s system 100% cpu 2:28.93 total | | 7.10 build: | 163.38s user 2.14s system 100% cpu 2:44.64 total | | 7.8 build: | 129.12s user 2.30s system 101% cpu 2:10.09 total | | | Please let me know if you have any questions. | | -- | Chris Allen | Currently working on | https://na01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fhaskel | lbook.com&data=02%7C01%7Csimonpj%40microsoft.com%7Cc4d32126857a47dd4dd | 008d49c86aa7c%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C63630554959 | 7208612&sdata=vVpn%2FeGOPMspkvoj9SRl2nvc1CIpE0lZbnXYhyTu%2B9Y%3D&reser | ved=0 | _______________________________________________ | ghc-devs mailing list | ghc-devs@haskell.org | https://na01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fmail.h | askell.org%2Fcgi-bin%2Fmailman%2Flistinfo%2Fghc- | devs&data=02%7C01%7Csimonpj%40microsoft.com%7Cc4d32126857a47dd4dd008d4 | 9c86aa7c%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C6363055495972086 | 12&sdata=G7cskVvK6Gp7mGLxGbSFPHm4MAQqav69A8PftobVsLE%3D&reserved=0
