To profile the creation and drawing, create a canvas and do a #fullDrawOn: onto
it.
Example:
[
| morph canvas |
morph := FTTableMorph new
extent: 300@300;
dataSource: (FTExampleDataSource elements: (Smalltalk
allClassesAndTraits
sorted: [ :a :b | a name < b name]));
yourself.
canvas := FormCanvas
extent: morph fullBounds extent
depth: Display depth.
morph fullDrawOn: canvas
] timeProfile.
Best regards,
Henrik

Thierry explained:
Show halos on a Morph, inspect morph, DoIt [self fullDrawOn: Display getCanvas]
timeProfile in the inspector.
I've noticed very large differences in where time is spend (and not just the
first time when all default values still need to be calculated).
