On: TechEmpower Framework Benchmarks: Round 20

[da_big_ghey]

Random question: why is rocket so low in the rankings? Especially since something like actix is very high.

[Freaky → da_big_ghey]

Probably the lack of HTTP keep-alive support - it's explicitly disabled due to bugs in the older HTTP library the stable version uses (seen as a large number of errors in previous rankings), so each request needs a new TCP connection.

[swsieber → da_big_ghey]

The latest stable rocket release doesn't use async, actix does.

The master branch of rocket does have async (and stable rust, not nightly!) support.

[yen223 → swsieber]

If there's one lesson to draw from benchmarks like these, it is how important non-blocking IO is to high-performance web services

[lmm → yen223]

It's super important for highly concurrent, low-compute web services. Whether that's actually your business requirement is very situational.
