It would be worth profiling the Bryce> startup sequence to see if any obvious bottlenecks can be identified. Given Andrew's results from profiling jonas, I would venture to guess that stack trace performance is a problem. Last time we looked at Eclipse startup performance, the single biggest improvement was in this area. (People sometimes ask why Eclipse startup time matters. The performance of some other Eclipse operations, like opening a perspective, is related to the startup time -- a lot of the same sort of work happens. Improve startup time and you improve some other visible things in Eclipse.) Tom
