------------------------------------------
Summary: Find usages is very slow in Netbeans 9.0 and it sits a
long time at Initializing data and Usages progress bars without showing any
progress at all
Key: NETBEANS-1269
URL: https://issues.apache.org/jira/browse/NETBEANS-1269
Project: NetBeans
Issue Type: Bug
Affects Versions: 9.0
Environment: Netbeans 9.0 on Windows 10 Pro
Reporter: Ciprian Bulboaca
Find usages in Netbeans 9.0 is very slow (compared to Netbeans 8.0.2).
For example, in our large modular project we have, doing a find usages on any
method in any class takes a very long time (4-5 minutes) in Netbeans 9.0. For
about half the time, Netbeans 9.0 is just sitting at "Initializing data" and
for the other half, it is just sitting at Usages progress bar always showing 0%
progress! Then, after a long period of waiting, it just shows the results
without even updating the progress bar (or at least you can't tell it is
updating the progress bar).
This all behaves normally under Netbeans 8.0.2 where find usages is showing
results right away (as it's scanning) and the whole process takes only a few
seconds!
We've tried bumping up the -J-Xmx setting to 1536m in netbeans.conf and
although we see the memory allocated is increasing (in Task Manager), Netbeans
9.0 behaves the same way.
I'm wondering if anybody else is experiencing this. Is there any workaround for
this issue? This affects our day to day work very significantly since we rely
on fast 'find usages' operations all the time in our analysis & coding work.
