Mickael Istria commented on JBIDE-16856:
----------------------------------------

I have the impression that the slow startup is caused by activation of Central page. Here is a stack I could get when I found startup slow

>            Reporter: Mickael Istria
>            Priority: Critical

>
> On Ubuntu 12.04 x86, I used Eclipse Luna M6 JEE package, installed JBoss Tools "Abbriged" category. Next startup has UI thread frozen for several minutes.
> It looks like a long operation is running in UI Thread instead of being in a job.
> I've put this in Central component, but I don't know what component is actually responsible of this latency.
