Hi, definitely interested. I have just talked about this with Richard yesterday, and we quite agree with what you observed. As the maintainer of http://perf.haskell.org/ghc, I’d very much welcome better data! Note that fibon already has bitrotted, and does not quite work any more. So there is some low hanging fruit in resurrecting that one. Simon mentioned a few points, such as dependencies. But note that you can relatively easily dump the dependencies’s modules in your source repository to both bundle and freeze them. I’d prefer that to (even strict) dependencies to something external, as that lowers the barrier for developers to actually run the benchmarks! Another important step in that direction would be to define a common output for benchmark suites defined in .cabal files, so it is easier to set up things like http://perf.haskell.org/ghc and http://perf.haskell. org/binary for these projects. About the harness: haskell.org is currently paying a student (CCed) to setup a travis-like infrastructure based on gipeda (the software behind perf.haskell.org) that would allow library authors to very simply get continuous benchmark measurements. Let’s see what comes out of that! Greetings, Joachim Am Montag, den 04.04.2016, 01:06 -0400 schrieb Ryan Newton:
Hi all,
Is anyone currently working in, or interested in helping with, a new benchmark suite for Haskell? Perhaps, packaging up existing apps and app benchmarks into a new benchmark suite that gives a broad picture of Haskell application performance today?
Background: We run nofib, and we run the shootout benchmarks. But when we want to evaluate basic changes to GHC optimizations or data representation, these really don't give us a full picture of whether a change is beneficial.
A few years ago, fibon tried to gather some Hackage benchmarks. This may work even better with Stackage, where there are 180 benchmark suites among the 1770 packages currently.
Also, these days companies are building substantial apps in Hackage. Which substantial apps could or should go into a benchmark suite? I see Warp and other web server benchmarks all over the web. But is there a harness that can time some of this code while running inside a single-machine, easy-setup benchmark suite?
Best, -Ryan
