Hi,

I use Eclipse for Java development.

My eclipse is painfully slow.  Other large Java programs run fast on the same box.  I have a dualcore processor; 2.2 Ghz each code.  Eclipse easily takes 70-90% of both CPU power combined.    Multiple threads are taking too much performance.  Also, Content Advisor is painfully slow.  Many times, eclipse hangs for 20-30 seconds  while editing.  


This issue is related to http://www.eclipse.org/forums/index.php?t=msg&th=166447&start=0  However, my issue may be deeper that the one discussed in the bug report.

Can you please suggest me what I can do debug this issue?


Thank you.


Reproducible: Always

Steps to Reproduce:
1.  It happens all the time for me when I use large .java files  and large number of windows open etc.
2.
3.

By this, do you mean that you're editing jspx files? Or is your code pure java code?

You can check out http://wiki.eclipse.org/index.php/How_to_report_a_deadlock#Getting_a_stack_trace_on_Windows and submit a few thread dumps which will help us figure out this issue.

You may also like to try out 3.5.2 or the latest 3.7M1 if you can and see if the problem is fixed in these. Anyway, whatever has been already discussed in http://www.eclipse.org/forums/index.php?t=msg&th=173308&start=0 should also be taken into account. :)

No feedback for almost a month. This is definitely not critical then.
