benchmarks

[devsnek]

i've been using both autocannon and wrk2 to benchmark this library and i'm simply unable to have the following code handle more than ~32,400 requests per second (still a great bump up from node's ~17k).

const BUF = Buffer.from('hello, world');
turbo.createServer((req, res) => {
  res.end(BUF);
});

i would imagine that the changes that were made to the codebase since the first commit may have introduced performance regressions, but if that isn't the case i'm quite curious about your setup that got 100,000 requests per second

i ran a prof and found the bottleneck seems to be http-parser-js unless i'm reading this wrong

I used this branch of autocannon, https://github.com/mafintosh/autocannon/tree/turbo

[devsnek]

@mafintosh using that branch has no statistically significant effect for me :(

[mafintosh]

How much do you get against node core?

[devsnek]

node http: autocannon and wrk2 ~13-17k turbo: autocannon ~27k, wrk2 ~32k

[mafintosh]

Right. Then it might just be a faster computer I tested on

[mafintosh]

If you wanna commit some benchmarks to the repo that'd be cool :)
