@nodejs/benchmarking could you help me benchmark this vs current master? I've a feeling that we might be sitting on a performance improvement here.

@joyeecheung I'm really newbie when it comes to benchmarks, but how long does it usually take to complete?

[lpinca]

http benchmarks take days to complete 😄

[joyeecheung]

@indutny The majority of time spent on HTTP benchmarks are on http/simple.js, I think @AndreasMadsen talked about changing it to slow down the run time in another PR?

[AndreasMadsen]

@joyeecheung Yep, see #18003 (comment)

[indutny]

@joyeecheung looks like benchmarks are completed. Is there any way to format it nicely? Thanks!

Also, see https://gist.github.com/joyeecheung/b55c88ee465d552d7ed1dc34e67305ea on how to grab the results (hmm, looks like a good candidate of node-core-utils)

Thanks!

Looks like benchmarks are inconclusive. Some are 10% faster, some are 10% slower. Unless there're any objections to this, I'd like to land for the sake of correctness of code.

[indutny]

Landed in f29c2cb, thank you!

[MylesBorins]

Should we land this on LTS? It lands cleanly on 8.x, but would need to be backproted for 6.x

[indutny]

I wouldn't bother.
