Hi Micahel,
I've not myself noticed anything slowing down this much - and not chewing
up the CPU (this is when developing AJDT itself). It definitely should not
be showing this behaviour :-)
Could you provide more information about your setup? Which version of
Eclipse are you using? Are the projects you're opening particularly big?
Do you have any other plugins installed? If you're seeing this repeatedly,
then could you raise a bug so we can investigate this further? Performance
is one of the areas we're about to start looking at and any information
you provide would be very useful.
Thanks, Helen

Hi Michael,
I think I've figured out why this is happening. It should only be an issue
when opening or closing large projects. Someone else on this group seems
to have hit the same problem. Here is a copy of my post on that thread:
This should be improved in AJDT 1.2.0M2. I managed to reduce the scope of
our resource change listener to avoid processing deltas for non-AspectJ
projects. I'm also going to ask the Eclipse team if there is a better
solution here, or whether one can be added in the future, because there
still seems to be an overhead in calling our listener, even if we do
nothing with the delta.
Regards,
Matt.
