[Sugar-devel] [DESIGN] Test startup animations

[Gonzalo Odiard]

Hi Benjamin,
I can't talk about timings without testing your code, but I am for any
change we can do to
accelerate the startup of activities.
My code do the render of the svg only one time, and previous timings we
found this operation
have a big cost. Probably we can accelerate the animation more with server
side operations,
but I am not an expert.
Any help is welcome

Gonzalo
