Ok. Maybe I exaggerated a bit. It consumes much time. But it seems to share it
with my application. Shortly after boot I see something like 70-80% for gc and
20% for my app. But this changes after a few seconds.
VFS: Mounted root (jffs2 filesystem).
Freeing init memory: 76K
<6 seconds pause>
init started: BusyBox v1.00 (2005.01.04-08:42+0000) multi-call binary
<1 seconds pause>
Please press Enter to activate this console.
After this gc is still running.
