[jira] [Commented] (NETBEANS-2409) Very Slow Operations on Windows
[ https://issues.apache.org/jira/browse/NETBEANS-2409?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16965342#comment-16965342 ]
flexJoly commented on NETBEANS-2409:
------------------------------------
Hi,
I just installed v11.2. And Netbeans performs indeed nicely, but only AFTER a very slow install.
I noticed the following:
* importing the userdir from 11.1 took more then 10 minutes. I thought it was hanging/crashed, but in explorer i saw the new user-dir growing....
* when starting netbeans, it started with a new background scanning of the projects. For our framework-project and 5 normal projects it took more then 20 minutes.
* memory-usage is over 60% according to win-taskmanager (at background scanning)
I cán understand that it takes so long to copy the userdir.
But why then does it need to do a new background scanning of the projects??
Is that not inside the (imported) user dir? Or inside the projects-dir?
Maybe here things can be done to get this better.
Greetz, flexJoly
Some specs:
Win10, x64, i3 (year: 2009), upgraded memory to 7gb, and new ssd harddisk (this year)
All my projects are PHP, with smarty, gulp, nodejs, npm etc. We have a central in-house framework project.
This framework project is always open in netbeans (I am the maintainer of it).
I installed 11.2 from: [https://www.apache.org/dyn/closer.cgi/netbeans/netbeans/11.2/netbeans-11.2-bin.zip]
Because the .exe could not find c:/jdk-12

> Key: NETBEANS-2409
> URL: https://issues.apache.org/jira/browse/NETBEANS-2409
> Project: NetBeans
> Issue Type: Bug
> Affects Versions: 10.0, 11.0
> Environment: Windows
> Reporter: Laszlo Kishalmi
> Priority: Critical
> Labels: Performance, Windows
> Attachments: NB11_autocomplete.nps, NB11_getHint.nps, WinFilesystemSlow.png
>
> Time Spent: 1.5h
> Remaining Estimate: 0h
>
> 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.
