Description Tomas Zezula 2009-12-16 14:11:01 UTC

The apisupport project slows down the Go To Type in order of magnitude.
See the snapshot: http://statistics.netbeans.org/analytics/exception.do?id=318561
9053ms - apisupport project vs 181 ms java.source + lucene

Comment 1 Jesse Glick 2010-02-01 11:43:31 UTC

In that snapshot, a bunch of projects are getting loaded. Most of the time is spent in filesystems.EventControl.exitAtomicAction. Over 2/3 of the thread's time is inside RequestProcessor.Task.schedule, which has been called 384 times, which looks excessive to me.

Assuming this is not really a P2 unless (a) it is clearly reproducible, (b) it affects _all_ NBM projects, not just those in the netbeans.org source tree.

Comment 2 Jaroslav Tulach 2010-04-15 15:23:17 UTC

Can I mark this issue fixed when I speed up RequestProcessor by 20%? core-main#4d36a0faa1b4

If you point me to some new snapshot, created after my fix, I can address another issue.

Integrated into 'main-golden', will be available in build *201004160201* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
Changeset: http://hg.netbeans.org/main/rev/4d36a0faa1b4
User: Jaroslav Tulach <jtulach@netbeans.org>
Log: #178755: Less contention obtaining the Logger (used to be a global lock), now it is final static variable without any sycnhronization. This shall speed up the case described in #178755 by 20%.
