When this happens, do you see "SGX" mentioned in "dmesg" output?

Don't know, but I'll try hard to not forget to check that next time round.

If it's as low as on desktop, you can get hitches while using the
device.  Something below 100 may be better though.

Is echoing value to /proc/.../swappiness a right way of setting this at runtime? Is there any /etc/sysctl.conf equivalent where I could store this value for boottime?

The device itself sets swappiness from /etc/init.d/rcS file,
but I would say that in general one needs to be pretty sure
of his/her changes when modifying essential bootup scripts. :-)


I have swappiness of 60 right now, we'll see how it goes.


As to memory usage, there are e.g. tools like sp-endurance from
tracking resource usage changes in the device:
http://wiki.maemo.org/Documentation/devtools/maemo5/sp-endurance
http://wiki.maemo.org/Documentation/devtools/maemo5/sp-endurance-postproc

(First you collect the data and then you post-process it after
collecting.  You can run the python scripts for latter even on
the device.)
