Hence graphics output necessarily lags input on Morphic. So these speed
differences have nothing to do with vm performance and everything to do with
GUI architecture.
Both Squeak and Pharo show the same delay for text selection latency. The
architecture difference is not likely causing

And they chose one that wasn’t too optimized. There are much better versions of
factorial already implemented in Smalltalk:

http://forum.world.st/Challenge-Tuning-th
It seems that someone needed an optimized factorial-routine…
The problem on the other hand is, that the machine friendly code is much less
„didactical" than the human friendly common implementation. To have both I
propose to add the human friendly clear and short version as comment. Its a bit

I forgot to mention that Pharo Zinc with all those primitives produces an HTTP
data transfer rate (CSV data) twice as fast as VW’s HTTP client. I tested it
many times. Pharo HTTP (Zinc) is consistently 2x faster than VW HTTP. This is
probably more about the judicious use of primitives than th

Generally, comparing VisualWorks to either Squeak or Pharo or both, what are
the most pressing speed problems?

In very general terms, the fork was due to their being Group A wanting to

Squeak 5.3:
Time millisecondsToRun: [ 10 factorial ] 6250
Pharo 8:
Time millisecondsToRun: [ 10 factorial ] 7736
Why the difference?
I have no idea. But I have to say that IN MY MACHINE:
Squeak 5.3, just downloade:
Time millisecondsToRun: [ 10 factorial
Hi,
Apples and oranges here.
Yes, both are fruits (perceived speed), but that’s the only point in common :)
Apples and oranges because one thing is the overall performance of the
environment and another completely different the perceived execution speed of
the GUI.
Still, some answers:

Arithmetic changes proposed in Squeak have no relationships to VM.
The question below is about both the VM and a common basic class-set.
Math-related classes/methods are assumed to be part of that common class-set.
Why is that not so?

There is an issue about incorporating Squeak arithmetic changes in Pharo:

I start to understand what could be done and could not find time to do the
changes.
