Hi all.

Squeak 5.3:��

����Time millisecondsToRun: [ 100000 factorial�� ] 6250

��

Pharo 8:

�� Time millisecondsToRun: [ 100000 factorial�� ] 7736

��

Why the difference?

��

Squeak 5.3 release notes describe arithmetic improvements.�� Nice.�� I crunch very big numbers, and these improvements therefore have value.�� Why would they not be included in OSVM (forked or not) and the basic class-set for both Squeak and Pharo?

��

Playing with Squeak 5.3, I���ve noticed that the GUI is snappier.�� Browser ergonomics are better too (for me at least), but that can be fixed/tuned in either environ to suit the developer.�� (Still that���s some work I prefer not to do.)�� Pharo GUIs are now generally slower, except for the Launcher, which is delightfully quick because it is written in Spec2.�� I presume that all Pharo GUIs will eventually (ETA?) be written in Spec2 and that Pharo will then be quick in all its GUIs.�� The obvious question is:�� Will Squeak be improving GUI look/behavior and speed with Spec2?�� If not, can I load Spec2 into Squeak so that I can do new GUI work there?

��

Both Squeak and Pharo have slow text selection.�� Pick any word in any pane, and double click it to select it.�� When I do this, I sense a 75 to 100 ms latency between the end of the double click and the selection highlight appearing on the word.���� I thought I���d entered a wormhole.�� So I did the same experiment in VW 8.3.2, VS Code, and Notepad, and all three showed undetectable latencies.���� This matters to me.�� I���m trying to port from VW to Pharo or Squeak (for a really long time now), and can���t push myself past the text-selection delay problem.�� Can text-selection speed be improved to the level of VW���s?�� ��Can someone sketch the algo used and/or point me to the right class/methods.��

��

The Squeak debugging experience step-to-step is much quicker.�� The latencies in Pharo after button- release are very long.�� I estimate 100 to 150 ms.���� That���s too long for me to work productively.�� I lose my mental thread with many of those delays, and have to restart the thought.�� It���s a serious problem, caused mostly by acclimation to no detectable latency for many years (Dolphin and VW have quick GUIs).�� Is speeding up the Pharo debugger with Spec2 a priority?�� I can���t think of a better GUI-related priority for Pharo.

��

��

Not speed-related:

��

-�� How can I load additional fonts into Squeak?�� Pharo does this with the font dialog���s Update button.

��

- Where in the Squeak and Pharo images can I change mouse-selection behavior to be leading-edge?�� Some of the Squeak panes have this; others don���t.�� I want leading-edge action in all panes, and wish the feature were in Preferences/Settings.
