Description Oleg Besedin CLA 2006-02-14 12:13:50 EST 
There is a 10% degradation in M5 of the UI startup perfromance (comparing to the Eclipse 3.1). 

From the initial check, it seemed to be related to the increased usage of the registry by the UI workbench. (Number of calls to registry APIs increased by a factor of 1.4 to 1.9.)

It might be worth while to investigate if the performance of the registry can be improved to offset this.
Comment 1 Oleg Besedin CLA 2007-03-29 17:24:02 EDT 
Closing as:
1) this bug is stale; it was created for Eclipse 3.2
2) the degradation described is relatively mild and was treated as "acceptable"
3) the most likely cause of the performance drop: a new UI command infrastructure was added, but the old one was kept in place for backward compatibility. Not much can be done on the core runtime / Equinox side.
