The browser tests drive one person against a handful of feeds, one request at a time, and cannot
show what production's load does. node tests/load/run.js builds a release binary, serves 1,500
generated feeds from itself, starts a daemon of its own under /tmp/ipx-load, seeds a hundred
listeners with thirty feeds each and four downloaded files, and runs four k6 scripts, with
`ipx status` -- the healthcheck -- run every second and failing the run at its 5s timeout:
browse 25 people at once: feed list, All Subscriptions, a feed, a search, the Directory,
a feed's page in it
listening 100 players saving positions every second and marking items read while scans write;
each reads its own state back, which must be as it left it
media 50 listeners seeking: every range checked byte for byte against the served file
signin a flood of wrong passwords while others browse, and the gap between refusing a
known name and an unknown one
Each budget is about twice what it measures now. Getting here found #135 (SQLite waiting for the
disk after every write, a first scan of 1,500 feeds estimated at 50 minutes, now 27s), #136
(SQLite's single connection, left open), #137 and #138 (fixed in the commit before this). k6 is
installed from its own signed apt repository by /src/install.sh, outside this repository.
