haskell-perf / serialization Goto Github PK

It seems estPoint has moved into a different module.

We're not serializing anything in 2 ns ;)

I'm sorry I don't have a PR for you, as I didn't care about packman and ripped it out and added some of my own benchmarks. But this sort of thing should yield meaningful numbers:

class Serialize lib a where
    serialize :: lib -> a -> BS.ByteString
    deserialize :: lib -> BS.ByteString -> a

instance (B.Binary a, NFData a) => Serialize Binary a where
    serialize   _ = LBS.toStrict . B.encode
    deserialize _ = B.decode . LBS.fromStrict
...
        bgroup "serialization"
          [ bench "binary"  $ whnf (serialize Binary) tree
....

Thanks for putting this together; it was very helpful!

One very useful application of these serialization libraries is to send data between Haskell servers and Haskell/GHCJS browser clients. It would be nice to see how they perform in GHCJS / whether or not they work.

I'm assuming that Multi-Language should be safe, and Haskell should be fairly safe, but Haskell-Same-Architecture clearly not.

Besides this issue flat seems to work ok in GHCJS for example.

I see that in table not the latest versions of libraries are used. So numbers might be outdated.

If anyone's interested, you could also summarize the output like this:

https://github.com/haskell-perf/sequences#append

I wrote a (not pretty, but works) script to do this here: https://github.com/haskell-perf/sequences/blob/master/Report.hs

It accepts a .csv file, which you can get by passing --csv out.csv to your criterion benchmark.

There's some code in there to replace anything after <!-- RESULTS --> in the README.md with all result tables, but you could do something else with that. Perhaps just replace a line containing <-- RESULTS -->, or just spit it out to stdout and do what you like with it.

Just a FWIW. I think the table is a nice quick summary, but that in the case of serialization it's nice to also include the full criterion output, as well.
