Hi, curious to try this out on various other platforms as well. How have you been running benchmarks to compare this? I guess any perf loss due to losing sendmmsg...

So I finally got round to doing some kind of decent tests on this. I used our setup to notice performance regressions on our end. It's not perfect, but it's...

> @flub recently discussed some benchmarking results in [#1729 (comment)](https://github.com/quinn-rs/quinn/pull/1729#issuecomment-2021022434) which indicate that there might be a performance regression on main compared to 0.10. @flub would you be able to...

Apologies for taking a while, I've made some attempts at bisecting the performance regression and can't really identify anything reproducible and certain enough. The only path remaining for me is...

So this idea came from @Ralith on matrix, I tried to put it down in an issue but may have some pieces wrong. Please correct me if so. It is...

I think the small writes part of this issue is probably already sufficiently addressed by e.g. tokio's `BufWriter` to wraps the `SendStream`.

This also found a real bug: https://github.com/deltachat/deltachat-core-rust/pull/4249

I am completely stumped by the test failure since merging master... it's not a flaky failure.

oh wow, i completely lost sight of this. yes, i'll update it

I looked a bit at the failures now. And while I could fix them I'm a bit unsure how to proceed: The failures occurring are because async drop is difficult....
