opium in techempower frameworks benchmarks

[mudrz]

not really an issue, but just letting you know that opium was added to the techempower frameworks benchmarks
https://github.com/TechEmpower/FrameworkBenchmarks/tree/master/frameworks/OCaml/opium

it didn't catch the last benchmarks run until a planned update of their tools TechEmpower/FrameworkBenchmarks#6064

so the next benchmarks run will be delayed indefinitely

in the meantime please feel free to make changes and improvements

Hi @mudrz,

That's awesome, thanks a lot for doing this!

I'm very curious to see how the next version of Opium (w/ Httpaf) will compare with the one you used for the benchmarks (w/ Cohttp). The benchmarks showing a better performance of Httpaf compared to Cohttp are at least 3 years old and Cohttp evolved a lot since then, so I wonder if they still stand.

in the current implementation opium is pinned to a master commit with httpaf

https://github.com/TechEmpower/FrameworkBenchmarks/blob/21bb27fbbfb778e09cf048efd2e87af84c883097/frameworks/OCaml/opium/src/Makefile#L10

https://github.com/TechEmpower/FrameworkBenchmarks/blob/21bb27fbbfb778e09cf048efd2e87af84c883097/frameworks/OCaml/opium/opium.dockerfile#L15

but it's really easy to add a new dockerfile and use the cohttp version in order to compare

edit: didn't notice that the httpaf version has a new API, so it's it would need more work to create a benchmark with cohttp;

also there are now results:

There is something wrong with the plaintext results, not sure if it is in my implementation, or perhaps there's something in opium?

Hi @mudrz,

There's definitely something going on with the plain text serialization. I'll look into it as soon as I have some spare time!

Thanks again for doing this, it's great to see where Opium positions itself in comparison with other frameworks 🙂

[mudrz]

the plaintext issue is related to httpaf and should be fixed:

(but there doesn't seem to be a new release)
