Chromium: same page, same machine, idle, Firefox 24.2% of a core against Chromium's 11.4%. The build comes from archive.raspberrypi.com (a "+rpt" version) and is patched for this board's V3D GPU; Debian ships a much older chromium, so the archive matters. The whole userland here is 32-bit armhf on a 64-bit kernel, which Firefox handles worse than Chromium does. --use-gl=egl, --enable-gpu-rasterization, --ignore-gpu-blocklist and --enable-zero-copy are what keep rasterization on the GPU: Chromium's blocklist does not recognise this driver and silently falls back to software without them. pi_kiosk_browser: firefox still works, as the fallback if an update ever regresses. Debug mode also gains xdotool, scrot and --remote-debugging-port=9222 (on 127.0.0.1), because firing XTEST key events at a window lands about half the time and a benchmark you cannot verify the state of is worse than none. pi_squeezeserver gains an absent path, and mediapis.yml derives its state from mediapi_has_squeezeserver, which defaults to false for the whole group. false means "actively remove", not "skip": musicdolphin has been running a Logitech Media Server that no playbook installs and nothing talks to - every squeezelite in the fleet points at pi_squeezelite_squeezeserver (192.168.178.80, the server) - while costing ~30 MB resident and ~47 MB of swap on a 2 GB Pi that also drives the kiosk. The absent path stops it, purges the package, unregisters it from sysdweb, drops the port 80 -> 9000 redirect and deletes its database and logs. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

pi_squeezeserver
The Logitech Media Server (logitechmediaserver, the daemon formerly known as
squeezeboxserver), plus its pi_sysdweb registration and a port 80 -> 9000 redirect.
pi_squeezeserver_state picks a direction:
present- install it and run it (tasks/present.yml).absent- stop it, purge the package, unregister it from sysdweb, drop the iptables redirect and delete/var/lib/squeezeboxserverand/var/log/squeezeboxserver(tasks/absent.yml).
mediapis.yml derives the state from mediapi_has_squeezeserver, which defaults to
false in group_vars/mediapis.yml. That default is deliberate and is a policy, not
an oversight: no media pi runs its own LMS. Every squeezelite in the fleet is
pointed at pi_squeezelite_squeezeserver (192.168.178.80, the server) by
inventory.yml, so a server running on a pi has no clients. musicdolphin had one
anyway - left over from earlier provisioning, since no playbook has installed it - and
on a 2 GB Pi also driving a kiosk browser it was costing ~30 MB resident and ~47 MB of
swap for nothing.
Set mediapi_has_squeezeserver: true in a host's vars if one ever genuinely needs it.
