Ok, I will move it to jboss.org - I posted it to mojo because usually performance results are internal AFAIK.

I will try to push some other things aside and focus on performance before JBDS9 Beta arrives.

I'm cc'ing this on jbosstools-dev@ so those who are working on the
related issues can chime in too.

we have multiple reports over the last releases that our CDI and JPA
tooling gets slow on large projects.
Latest one was discussed on irc:
http://transcripts.jboss.org/channel/irc.freenode.org/%23jbosstools/2015/...
(look for "attiand")

which doc exactly ?

+100

Snjezana tend to be good at finding causes, but performance is important
for us all, so ask away here in jbosstools-dev and #jbosstools chat.
First you should do is grab a a few jstack's of that eclipse when it is
freezing and see what is showing up in the stack trace.
If that does not reveal anything connect a profiler (jvisualvm might be
enough) to spot the hotspots for your case.
