Attached is the output from running health-check (found in PPA:colin- king/white) on init pid 1114. Key points: 1. messages being read/written at ~600 messages a second, hence the high context switch rate and ~4.9% CPU load. 2. heap consumption: ~30K a second using brk() and 2K a second via mmap To reproduce: Install health-check: sudo add-apt-repository ppa:colin-king/white sudo apt-get update && sudo apt-get install health-check Download a large mp4 to the phone. Keep screen from blanking using: sudo powerd-cli display on bright & then play the mp4: dbus-launch mediaplayer-app test.mp4 --desktop_file_hint=/usr/share/applications/mediaplayer-app.desktop --stage_hint=main_stage And then observe that init is busy for 300 seconds: ps -e | grep init 1 ? 00:02:56 init 348 ? 00:00:00 init 1114 ? 00:03:22 init sudo health-check -p 1114 -d 300 Attached are my results for a 30 minute run.
