Ha, ahat age group is Knuth teaching assembly to?? What level of math and

Python is not the problem. Just strace the activity startup process to see
everything that goeson.
A lot of it appears to be erelated to
b) Journal instance creation
Also I agree that the huge animated loating icon is probably not helping on
XO. Could'nt it be replaced by a large non-animated icon in the center of
the screen, and then smoe dots that appear around the icon in a circle,
adding one dot per second, like a clock? That would take no overhead and
would even give an informal way to measure startup time by counting the

Please don't try to hijack a technical discussion into a political one. Use
of the Python language is not the cause of the performance problems on the
XO or in Sugar in general. Every system must be optimized no matter what
language it is written in. It just takes a little effort.
