[Sugar-devel] Debugging Sugar 0.100 on Cubieboard.

[Iain Brown Douglas]

I am running Sugar on Fedora-xfce-20-armhfp on a 1GB Cubieboard from
image [1], with kernel 3.4.75.sun4i+
        
I have Fedora 20, xfce, and sound running quite nicely on Cubieboard. In
Sugar there is a limitation - `some event` seems to overwhelm Sugar.

Deploying the Frame seems the culprit. Watching with conky, it now seems
reproducible that when the Frame is deployed the CPU suffers a great
overhead.

With cursor / hot corner action of Frame disabled, conky records
perfectly natural CPU and memory spikes on starting and running up to 3
(including sound-based) Activities. 
 
Having pressed F6, Sugar starts to perform poorly, Conky records CPU use
of 100%, which in 10 minutes does not recover. 

Running in tty2 and tty3, `top` and `ps -ef`

python2 rises to top CPU use, on pressing F6
no new process seems to be started by pressing F6.
If no Activities are running, I see only two python2 processes:
    python2 -m jarabe.main
    python2 /usr/bin/datastore-service


Can anyone throw some light on what is going on here, or tell me how I
might generate more useful evidence to debug this?

I have made an fpaste [2] of the shell.log together with notes of actions performed
in Sugar test.
