Re: Poor TTF font performance on Linux with newer VM

Tony Garnock-Jones-2
I've just checked against 3.9-4 (built from source tarball from
squeakvm.org), and it's still hideously slow. So it's down to something
that changed between 3.7-7 and 3.9-4. Or perhaps CroquetPlugin or
FloatMathPlugin. Or AioPlugin or UnixOSProcess :-)

Isn't that still the issue that TTF glyphs are not cached long enough  
anymore because of a fix to the garbage collector's weak ref handling?

Is there a fix in the image by now?

Wow. That could be interesting to test. I'll try saving and loading the
project with the BookMorph into a 3.9 image; failing that, I'll try
building a mock couple of pages similar to those I have in my 3.8 image.

I'll report back.

Thanks,
  Tony

Re: Poor TTF font performance on Linux with newer VM

Tony Garnock-Jones-2
I've just tried a similar setup in a 3.9b-7032 image with 3.7-7 and
3.9-svn, and I get

3.7-7 - 107 tallies, 120 msec.
3.9-svn just after Smalltalk garbageCollect - 990 tallies, 1005 msec.
3.9-svn otherwise - 1323 tallies, 1343 msec.

So either the glyph caching isn't aggressive enough for this use case (I
made sure to use a real-world text example, rather than homogenous
repeats of the same string), or it's some other problem.

Traces attached.

Regards,
  Tony
