"Change Set: MorphicOptimizations-nk
Date: 13 March 2001
Author: Ned Konz
This provides speedups in menu generation and
StringMorph creation and changing. It should improve
all Morphic text displays (browsers, etc.)
This resulted in a 36% speedup in TheWorldMenu>> alphabeticalMorphMenu
* Two duplicate
changed calls were removed from the critical path in
StringMorph>>contents:
* Morph>>invalidRect: was optimized to avoid calling invalidRect:from:
* wonderlandTexture calls were removed from Morph>>invalidRect:from:
THIS NEEDS TO EXAMINED; I REMOVED THESE:
self wonderlandTexture ifNotNil:[self isValidWonderlandTexture: false].
* StringMorph>>initialize defers setting its contents to 'String Morph'
until it actually gets an owner, eliminating an extra resize
* MenuMorph defers setting its properties until it has
a World to examine, so it doesn't have to search for a world
Speedups measured using:
Smalltalk garbageCollectMost. Time millisecondsToRun: [ TheWorldMenu
someInstance alphabeticalMorphMenu ]
406 original time
365 after changes to invalidRect: and invalidRect:from:
343 after changes to StringMorph>>initialize
313 after changes to invalidRect: and invalidRect:from: removing
wonderlandTexture
290 after changes to menumorph defaults from world
278 after removing duplicate changed call after extent: in
StringMorph>>fitContents
258 after another duplicate changed call was removed in
StringMorph>>contents
