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 :-)

I've just run "MessageTally spyOn: [3 timesRepeat: [self nextPage]]" on my BookMorph. The two results are dramatically different: on the 3.7 VM, 477ms for the whole thing; on the 3.9 VM, 50354ms for the whole thing! A factor of 100x slower.
Just wanted to mention that this might indeed be the issue I have been experiencing with the new VM in my IRCe image - I thought it had to do with Socket communication, but hey, it might as well be this in fact.

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
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.

I recall Andreas posting a fix to the squeak list earlier in 2006, or was that 2005?

I've just run "MessageTally spyOn: [3 timesRepeat: [self nextPage]]" on my BookMorph. The two results are dramatically different: on the 3.7 VM, 477ms for the whole thing; on the 3.9 VM, 50354ms for the whole thing! A factor of 100x slower.
