Hi,
has anybody investigated the BitBlt performance difference in
line-drawing between OS-9 and OSX?
For (an extreme) example:
TimeProfileBrowser onBlock: [
Display fillWhite.
1 to: 4 do: [:i | Pen new color: i; turn: 90*i; dragon: 14]]
results on my machine (PBG4 886MHz):
OS9: 6.7s
OSX: 455s
OSX CocoaSqueak: 479s
Tested with various VMs up to 3.5.2b1.
OS9 is nearly 70 times faster than OSX...
It gets weirder when you just run the "Squeak 3.5.2b1 Classic" (taken
out of the package) in the Classic environment. It has nearly the same
fast timing as when started under OS9 even though a restore Display in
that environment takes nearly 2s!
Any ideas?
