Subject: [PATCH 0/6] daemon: reduce fragmentation via preload
Date: Thu, 19 Mar 2020 03:32:50 -0500	[thread overview]
Message-ID: <20200319083256.15593-1-e@yhbt.net> (raw)

For long-lived daemons, perform immortal allocations as early as
possible to reduce the likelyhood of heap fragmentation due to
mixed-lifetime allocations happening once the process is fully
loaded and serving requests, since per-request allocations
should all be short-lived.

On a side note, I'm wondering if WWW should just preload by
default.  I'm not sure if anybody uses public-inbox.cgi (or
should be using it :P).  It's not like we don't ship
public-inbox-httpd; and any PSGI implementation could be used
for smaller inboxes (or powerful-enough hardware).

  www: update ->preload for newer modules
  wwwlisting: favor "use" over require
  wwwlisting: avoid lazy loading JSON module
  www: avoid `state' usage to perform allocations up-front
  daemon: do more immortal allocations up front
  viewdiff: favor `qr' to precompile regexps
