Subject: how's memory usage on public-inbox-httpd?
Date: Sat, 1 Dec 2018 19:44:29 +0000 [thread overview]
Message-ID: <20181201194429.d5aldesjkb56il5c@dcvr> (raw)
I haven't been around much, so not working on public-inbox means
fewer restarts :x
On my 2-core VM, I've been noticing public-inbox-httpd memory
spikes into the 500MB range, which is gross... It seems caused
by slow clients and large threads/mbox downloads. The PSGI code
only loads one email per-client in memory at-a-time when using
-httpd; but that adds up with many clients and larger messages.
I run two -httpd workers, one-per-core, but also varnish and an
experimental Ruby/C reverse-buffering proxy (yahns) for HTTPS.
The problem seems to be varnish isn't reading from -httpd fast
enough (and I lack CPU cores), but decreasing the niceness of
varnish seems to help with the problem...
