[Moose-dev] Re: Issue 971 in moose-technology: Using Athens fonts is dead slow in Roassal

Comment #2 on issue 971 by tu...@tudorgirba.com: Using Athens fonts is dead slow in Roassal http://code.google.com/p/moose-technology/issues/detail?id=971

After the fix, the same code works in 5s. To be mentioned that

[10 to: 100 do: [ :x | (LogicalFont familyName: 'Arial' pointSize: x) widthOfString: 'test' ]] timeToRun

takes a bit less than 5s on my machine. Thus, essentially, the time spent now on the rendering is only due to the first lookup of the fonts (no extra lookup is performed). This is reasonable and it will get better once we get a better caching at the Pharo level.

The cached font is reset on modelChanged:

I think this is a good enough solution.
