Is 6913/M1a slow for you too?

On this iMac 2.4Ghz Core2Duo 6913 is really slow when it comes to completions, code analysis and intentions. I can barely type a method without being interrupted with short delays that lock up the whole editor. This is a pretty small project and I disabled all plugins that I don't need. I do have Spring Facets turned on though.

It is fast on my SLED 10 dual core machine, but slow on my Win XP single core machine.

It's really slow on my Windows XP 2Ghz Core Duo machine as well. There are a number of JIRAs open for slow editing, so it may be worth attaching some CPU snapshots to one of them (e.g. IDEA-11775)

I installed it on my XP Pro laptop over the weekend. Haven't done any hardcore editing but I dont recall experiencing any problems. Am running it with :Xverify:none and pointing to JDK 6 Update 1. The IDE is really really fast. Have all the plugins except for the various VCS and Starteam etc those kinda plugins. Also got the websphere plugin and the plugin dev removed.

I am using JDK6 also and without many plugins, but still slow. It is not CPU. The processor will be idle, but the editor is very sluggish.

I'm running on JDK6U1 with the Xverify:none setting as well. The in-editor inspections just seem to cane my machine, although mainly only when I either have 2+ projects open or have split my editor windows.

I have a 2000 line file open right now and it is doing its analysis with the code inspection. It does it automatically whenever I go into the editor window....it takes a bit of time do perform the analysis but if I type some code and use the auto complete hint there is no lag. For example I type in System. and then hit Vtrl Space the auto completion window opens up right away while the inspections are running for that file.

I am running on OS X with Java5. Were there unresolved dual core issues on OS X? I remember reading something like that.

I know inherently OS X does not handle threading well as compared to say Linux or Windows...so the problems with dual core could well be aggravated.

If it's any consolation, it's also slow on my 8 core macpro (and randomly hangs).

...and any javascript or spring xml editing invariably causes it to run out of memory.

Hello Hani,

..and any javascript or spring xml editing invariably causes it to run
out of memory.


Usually taking a memory snapshot and uploading it to
helps.
That, and some nagging here or in JIRA ;)

Yeah, I'll try, I always end up postponing it thinking 'surely they won't release with it being so slow, I'll nag when it gets closer to release', and lo and behold, before I know it, the release is out of the door!

Except Hani gets a lot more attention when he's not nagging :)

Here's a concrete example of astoundingly freeze frame slowness:

Download extjs from extjs.com
Copy ext-all-debug.js into your project
Make any edits
Open up the original file in IDEA
Select the edited version in project view, and select 'view diff to edit'

Try to make edits in the diff viewer
Go drink tea, watch a movie, make new friends, attend a few conferences
Come back ,and you'll note that IDE is STILL trying to do something
A few days later, you'll get an OOM dialog.
Angrily force kill IDEA, post angry message on forums
Retart IDEA, avoid diff window on big js files like the plague

Sounds like http://www.jetbrains.net/jira/browse/IDEADEV-14279 (nothing specific
to JS).

same problem here (but just in bigger (10.000+ classes) projects), but not all the time. i cannot reproduce the lockups.´, they just appear when they like to.

edit:
i am experiencing no lock ups at all after i created a new project. maybe there are some old and evil cache files flying around?
