Description

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.
