Subject: [PATCH 4/7] http: use a larger buffer for ->getline responses
Date: Sat, 23 Oct 2021 18:20:42 -0600 [thread overview]
Message-ID: <20211024002045.17755-5-e@80x24.org> (raw)
In-Reply-To: <20211024002045.17755-1-e@80x24.org>
64K matches the Linux pipe default, and matches what we use in
httpd/async and qspawn. This should reduce syscalls used for
serving git packs via dumb HTTP and any ->getline code paths
used by other PSGI code.
This appears to speed up HTML rendering by w3m when serving
giant HTML responsees from the Devel::Mwrap::PSGI memory
debugger.
