Ole was right: doScript() with UndoModes.fastEntireScript gives the best results. The test was a document without any formatting, no undo history, containing 36,000 characters. The script creates a character style and sets underline to true. Then it finds all "A" and "a" (2,680 instances), changes the contents of each found instance with "x" and applies the character style.

Results:

UndoModes.fastEntireScript	22.6, 22.8, 23.1
UndoModes.autoUndo	25.8, 25.8, 25.9
UndoModes.entireScript	26.3, 26.4, 26.5
UndoModes.scriptRequest	29.9, 29,3, 29.2

Conclusion: fastEntireScript lives up to its name and wins hands-down.

My next step, I thought, was to add from now on this line at the beginning of labour-intensive scripts: 

      app.activeScriptUndoMode = UndoModes.fastEntireScript;




But unfortunately, activeScriptUndoMode is read only. Time for a feature request.
