@SimmerVigor I noticed this last week too, but figured it was because I'm always on some (buggy) preview version of MSFT stuff and that was likely the cause...

[Nick Banks @gamernb]

@programmingart @SimmerVigor 0-RTT case doesn't exchange certificates, so it's kind of a separate question. But, still, 10x seems like a lot to me.

[Nick Banks @gamernb]

Even after being deployed for years, it seems most endpoints haven't optimized their #quic certificates to fit in a single server flight OR they are just ignoring the spec and sending the whole thing anyways.

[Nick Banks @gamernb]

@programmingart @SimmerVigor That's essentially saying have no amplification limit, right?

[Nick Banks @gamernb]

@SimmerVigor So you think the 3x limit should be increased? To what? 5x?

One hour and 200 LoC later, I have a simple #MsQuic-based #QUIC terminating proxy. Still needs some work to be performant, but it shouldn't be a lot of work.

[Nick Banks @gamernb]

@djco @dwizzzleMSFT @ProssimoISRG @Microsoft @rustlang But long term, I do have interest in moving some of our code, likely starting with the parsing layers, to Rust.

[Nick Banks @gamernb]

@djco @dwizzzleMSFT @ProssimoISRG @Microsoft @rustlang Additionally, because of the test and tooling we have already to ensure quality of MsQuic, we don't actually have any data to justify a need to move to Rust immediately. After years of production deployment no memory safety issues have occurred.

[Nick Banks @gamernb]

@ladeak87 I'm not the expert at the .NET layer, but I think there's an issue related to having to copy MsQuic.dll into your local path for it to work.

[Nick Banks @gamernb]

@beyerscronje @Aaronontheweb As David already mentioned in the other thread, there is Preview support in .NET already. I expect the API is likely mostly stable, but there still likely is some work (in .NET) left to get it highly performant.

[Nick Banks @gamernb]

@djco @dwizzzleMSFT @ProssimoISRG @Microsoft @rustlang On the MsQuic side, we've had discussions about moving to Rust, at least in part. There are some things blocking that (official Windows kernel support). As far as using a different Rust library, none come close to the performance we have built with MsQuic.

[Nick Banks @gamernb]

@rosyna @NerdPyle That statement is specific to MsQuic. It does work with macOS, but it's not officially supported currently. We haven't had any official ask for support to move things forward there. We also lack experience on mac, so we're hesitant to take it in without specific needs.

[Nick Banks @gamernb]

@YMD_Glasses Definitely weird. Please open an Issue on GitHub, and if possible please follow the instructions there to collect logs. That should help us root cause this. Please don't hesitate to reach out further if you have any other problems.
