And here other interesting results:

Class allSubInstances size.
��"5636"��
Object allSubclasses size
��"11267"

What they are not almost equal?

Interesting. It takes very high amount of time on Pharo 2.0 too.

Dear Pharoers,

I found something strange:
Time millisecondsToRun: [ Class allSubInstances size ]. ���23617"

I did this on a new Pharo 5 image
curl get.pharo.org/alpha+vmLatest | bash

Can somebody confirm this on their machine? What might be the reason?

Cheers,
Bernhard
