For us to base our work on 0.101+ (new) Sugar, we have
to make sure we have solved the performance issues
plaguing (new) Sugar and/or OLPC/OS 13.x.<br>

<div>Which OLPC version are you comparing with? In the rest
of the answer I'll call that X.x :)<br>

Well we deployed an image based on 11.3 i.e. Fedora 14. However the
focus of my research is Sugar itself. I figure base OS issues are a
different beast and worth isolating for this first approach, that's
why I figured I wanted the same setup with different Sugar versions.<br>

For Christmas I got an Acer Chromebook c720, cost $US200, got 2GB
ram and 16GBSSD. Pretty fast Haswell based processor, coming from an
Atom netbook. Quite happy with the upgrade, btw.<br>

Anyway it's probably not going to be trivial. So let me
suggest an easier first step. You could test 0.94 activities
on the top of OLPC 13.x. If they perform the same as OLPC
X.x then we know the issue is the gtk3 toolkit (no change
was made to the gtk2 toolkit). If they are bad as stock 13.x
activities, then we will know it's something in the system.
If it's something in the middle we will have to come up with
a more complicated strategy. But I think the data we get
from this initial testing will be useful to figure out that
strategy.<br>

I will make the time to flash 13.2 on an XO1 and do this informal
test. However I has hoping to use my dev environment because I
really want a test that can be automated/done quickly, and gives
numbers, not just impressions.<br>

<div>For CPU top should be fine, but it depends what exactly
you want to test. For timing I usually just print out
time.time intervals from the code :)<br>

<div>See sugar-build/build/tests/shell.py, you could use
something like that to measure startup time I suppose.
Anyway you can use the same kind of code to click around
in activities UI etc.<br>

Is this what runs when you do ./osbuild check ?<br>
<br>
I tried but it's failing for me and I'm not finding the error. Below
is the output. shell.log and datastore.log in home/dotsugar/logs/
don't show any traceback either.<br>
