Description Dani Megert CLA 2003-11-04 11:35:54 EST 
I20031029 (or earlier)

1. Open JavaEditor.java in the Java editor
2. scroll down to half of file
3. type some text
==> editor blocks for some time

The time increases with the number of views that are linked to the editor, e.g.
Java Browsing perspective is a good test case.

There are several areas where the time can be spent:
- in the editor
- view updating
- in J Core (AST, codeResolve, reconciling the CU)
- delta processing of views
Comment 1 Dani Megert CLA 2004-02-10 07:30:57 EST 
The reason was that the Java Browsing parts reconciled in the UI thread. This
has been changed. See also bug 51290.
