[Sugar-devel] Cairo-ized activity performance

[Walter Bender]

I did some tests of some "Cairo-ized" activities on an XO-1 running
11.3.0. Turtle Art launched faster with Cairo than in the Drawable
version; Abacus a bit slower. Executing a program in TA took no
noticeable performance hit and the results are much nicer due to the
anti-aliasing. With Abacus, switching between abacuses took a
performance hit with Cairo. Dragging blocks in Turtle Art is seriously
broken Cairo, however. It seems that there is a refresh clipping
problem of some sort I need to sort out. It is not shippable in its
current form :(

Activity     Version      Launch time     Run time
TA           114            44 sec             30 sec
TA           123*            21 sec             30 sec
Abacus     29             15 sec             4 sec
Abacus     30*             21 sec             8 sec

* Cairo version
