[Newbies] How do I profile an application in Squeak?

[Clinton Blackmore]

Greetings.

I'm trying to make Enchanting <http://enchanting.robotclub.ab.ca/>, my mod
of Scratch that allows one to program LEGO Mindstorms NXT robots, work
reasonably well on the Raspberry Pi, where it is very slow.

How do I profile an application running on squeak (2.8, I'm afraid) so as
to see where time is being spent in order to know where to optimise?

Thanks,
Clinton Blackmore
