There might be a leak or two (especially in the PHP parser), though the
increased memory usage is due to we removed the 1 Gb cap on the NB
memory usage, allowing the JVM to decide on it's own which results ~2gb
usage on systems which have 8 Gb RAM or up. I have 32 Gb and NetBeans
memory usage rarely goes above 2 Gb.

NB has 2G. It sometimes gets up there and is using 1.8 of that. I suspect a
leak somewhere. That is much higher usage than NB 8.2 and when I restarted the
initial memory usage was over 1G less. But the stalls happen when usage is low.
So far this appears to be a Windows issue with file system calls that are
occasionally orders of magnitude slower than they should be.

Don’t suppose default java memory settings may also be coming in to play here?
Maybe bumping these up some might help?

Hi Scott,
I’d check to see if NB is in a long GC pause first. If not, then take 2-3
thread dumps during the slow bit and post them. Your project code will not show
up in the thread dump. You can use jstack to obtain the thread dumps. Just have
everything set to trigger (small script) so you don’t miss the event.
Kind regards,
Kirk

What is the best course of action for reporting slowness? I can’t share my
project.
I’m not certain how to give step-by-step instructions when the problem is
basically one step in most cases. E.g. invoke auto-complete - nothing happens for
several seconds. Invoke rename - dialog doesn’t appear for several seconds. Find
usages - extremely slow > 5 second delay on a private member of a class less
than 100 lines.
In general it seems NB 11 is noticeably slower than NB 8.2. Not good
considering slowness was already my #1 complaint about NB 8.2. I have so far
found the benefits of NB outweigh the fact that it is much slower than other
IDEs for the same operations, but the slowness of NB 11 is tipping the scale. I
don’t want to switch IDEs, pease don’t interpret this as some sort of threat to
do so. I would like to help find the issues in NB. But I don’t have the
bandwidth to debug NB and not being about to share my project makes it
difficult to provide helpful reports :-(
Are others seeing the slowness?
Find usages, renames, call-hierarchy, auto-complete… things I use all the time,
I often have to wait 5 to 10 seconds for a response from the IDE, sometimes
more.
I’ve already deleted user dir and cache and restarted.
I’m using Gradle-based Java projects, running NB 11.0 with JDK 8u202.
Is there a wiki page with instructions on profiling the IDE? Maybe I can
collect something useful.
