As far as I know, https://github.com/pyca/cryptography/issues/7236 is responsible for this issue. Even though cryptography is downgraded to 36.0.2, it still takes about 30 ms to verify certificate.

https://man7.org/linux/man-pages/man3/getaddrinfo.3.html > If hints.ai_flags specifies the AI_V4MAPPED flag, and hints.ai_family was specified as AF_INET6, and no matching IPv6 addresses could be found, then return IPv4-mapped IPv6 addresses in the list...

The CI failure only in "tests / package-wheel (ubuntu-latest, x86_64) (pull_request)" perplexes me, and it is perhaps attributed to operating system itself or CI misconfiguration.

Nevertheless, I could not reproduce CI failure, especially in this situation: ✔️ tests / test (ubuntu-latest, 3.10) (pull_request) ✔️ tests / test (ubuntu-latest, 3.9) (pull_request) ✔️ tests / test (ubuntu-latest,...

`time.perf_counter()` becomes system-wide on Windows since Python 3.10, which explains the CI failures. From my perspective, this issue should be fixed in Python, and there are three ways to resolve...

I think it is an upstream issue, so this PR should not be merged or closed until it is fixed in CPython. I just test whether aioquic functions well or...

I do not think so. The throughput in https://interop.seemann.io/ is restricted in 10Mbps link. Initially, I consider that the asyncio UDP contributes to the slow speed, and patched https://github.com/python/cpython/pull/91488 to...

I am also curious about how HTTP/3 is supported by NextDNS servers. According to https://http3check.net/, [Google DNS](https://http3check.net/?host=dns.google) and [Cloudflare DNS](https://http3check.net/?host=cloudflare-dns.com) support HTTP/3, but [NextDNS](https://http3check.net/?host=doh3.dns.nextdns.io). Moreover, what most attracts me is...

Since connection is reused, the differences of subsequent DNS query time are nearly indistinguishable among DNS over UDP, DNS over TLS, DNS over QUIC, DNS over HTTP/2, and DNS over...
