I do not know
I could not find a squeak image with the latest code and the update is not working from the june image.
Now the newtext model should replace all that but still
- we need to benchmark it
- release it

Me too.

What exactly doing this code?

Paragraph new compose: tm text
        style: tm textStyle copy
        from: 1
        in:

Is it layout building stuff at new text model?

Hi Igor

it would be good to see how the new text model perform.

Here is a simple bench:

(StringHolder new contents:  (Compiler evaluate: (FileStream fileNamed: 'text.st') contentsOfEntireFile )) openLabel:  'Working With Squeak 2' .
((SystemWindow allSubInstances detect: [:e | e label = 'Working With Squeak 2']) findDeepSubmorphThat: [:m | m class = PluggableTextMorphPlus] ifAbsent: [] ) textMorph
ifNotNil: [:tm | MessageTally spyOn: [
    [100 timesRepeat: [(NewParagraph new)
        compose: tm text
        style: tm textStyle copy
        from: 1
        in: tm container]] timeToRun]].

Before our changes: 162 ms
After our changes: 95 ms
And my Pharo 3.0 (#30417) (not up to date) :  364 ms

The main gain is avoiding
- the stopConditions copy
- and the TextStopConditions indirection
- and of course the Multi* when not necessary (Pharo does not)

Here is the test for Pharo variant:

| text |
text := Compiler evaluate: (FileSystem workingDirectory parent parent parent / 'text.st' ) readStream contentsOfEntireFile .
(StringHolder new contents:  text) openLabel:  'Working With Squeak 2' .
((SystemWindow allSubInstances detect: [:e | e label = 'Working With Squeak 2']) findDeepSubmorphThat: [:m | m class = PluggableTextMorph] ifAbsent: [] ) textMorph
ifNotNil: [:tm | MessageTally spyOn: [
    [100 timesRepeat: [(Paragraph new)
        compose: text
        style: tm textStyle copy
        from: 1
        in: tm container]] timeToRun]].
