On Linux GTK/64bit, opening of the "Find" dialog (Ctrl+F) sometimes is very slow, i.e. multiple seconds, with delay increasing over time of running the same Eclipse process. When taking threaddumps meanwhile, the following shows up: "main" prio=10 tid=0x00007f6d78009800 nid=0x50e0 runnable [0x00007f6d7fab2000] java.lang.Thread.State: RUNNABLE at org.eclipse.swt.internal.gtk.OS._gdk_window_at_pointer(Native Method) at org.eclipse.swt.internal.gtk.OS.gdk_window_at_pointer(OS.java:5261) at org.eclipse.swt.widgets.Shell.setToolTipText(Shell.java:2421) at org.eclipse.swt.widgets.Shell.setToolTipText(Shell.java:2389) at org.eclipse.swt.widgets.ToolItem.setToolTipText(ToolItem.java:1193) at org.eclipse.swt.widgets.ToolItem.setToolTipText(ToolItem.java:1167) at org.eclipse.jface.action.ActionContributionItem.update(ActionContributionItem.java:810) at org.eclipse.jface.action.ActionContributionItem$1.propertyChange(ActionContributionItem.java:113) at org.eclipse.jface.action.ExternalActionManager$CommandCallback.bindingManagerChanged(ExternalActionManager.java:281) at org.eclipse.jface.bindings.BindingManager.fireBindingManagerChanged(BindingManager.java:900) at org.eclipse.jface.bindings.BindingManager.setActiveBindings(BindingManager.java:2176) at org.eclipse.jface.bindings.BindingManager.recomputeBindings(BindingManager.java:1742) at org.eclipse.jface.bindings.BindingManager.contextManagerChanged(BindingManager.java:689) at org.eclipse.core.commands.contexts.ContextManager.fireContextManagerChanged(ContextManager.java:165) at org.eclipse.core.commands.contexts.ContextManager.setActiveContextIds(ContextManager.java:295) at org.eclipse.e4.ui.internal.services.ContextContextService.getActiveContextIds(ContextContextService.java:83) at org.eclipse.ui.internal.contexts.ContextService.getActiveContextIds(ContextService.java:256) at org.eclipse.ui.internal.contexts.ActiveContextSourceProvider.getCurrentState(ActiveContextSourceProvider.java:68) at org.eclipse.ui.internal.contexts.ActiveContextSourceProvider.contextManagerChanged(ActiveContextSourceProvider.java:50) at org.eclipse.core.commands.contexts.ContextManager.fireContextManagerChanged(ContextManager.java:165) at org.eclipse.core.commands.contexts.ContextManager.setActiveContextIds(ContextManager.java:295) at org.eclipse.e4.ui.bindings.internal.BindingServiceImpl.setContextIds(BindingServiceImpl.java:237) at sun.reflect.GeneratedMethodAccessor25.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:601) at org.eclipse.e4.core.internal.di.MethodRequestor.execute(MethodRequestor.java:56) at org.eclipse.e4.core.internal.contexts.ContextObjectSupplier$ContextInjectionListener.update(ContextObjectSupplier.java:88) at org.eclipse.e4.core.internal.contexts.TrackableComputationExt.update(TrackableComputationExt.java:107) at org.eclipse.e4.core.internal.contexts.EclipseContext.processScheduled(EclipseContext.java:318) at org.eclipse.e4.core.internal.contexts.EclipseContext.set(EclipseContext.java:332) at org.eclipse.e4.ui.internal.services.ContextContextService.activateContext(ContextContextService.java:53) at org.eclipse.ui.internal.contexts.ContextService$UpdateExpression$1.run(ContextService.java:128) at org.eclipse.e4.core.contexts.RunAndTrack.runExternalCode(RunAndTrack.java:53) -

Hi Jörg - I'm interested in trying to get to the bottom of this (and the other tabs issue). Can you tell me exactly the build, JRE and plugins you have installed? I'd like to try to replicate your setup. Also can you tell me about your workspace setup? What types of projects do you have? (If you are using open source projects I can try to recreate your workspace). What are the steps you take to get to this state? Does it happen right out of the box on startup? Do you have to work for an hour before things slow down? These types of bugs are hard to track down so the more data points the better. Thanks!
Hi Bogdan, great you want to have a look! The base installation was "Eclipse IDE for Java EE Developers" Juno / Eclipse 4.2, meanwhile updated to SR1 (Build id: 20120920-0800).

I'm right experimenting with different workspaces to find out whether it's related to what I have in the workspace, or what kind of editors or open or something like that.
It's great you asked about the workspace. I can reproduce it by simply opening a second POM editor from m2eclipse. With a single POM editor performance seems normal, but after opening a second things slow down noticeably. Steps to reproduce 1. download eclipse-jee-juno-SR1-linux-gtk-x86_64.tar.gz 2. install Subversive (from Marketplace) 3. install m2e (from Marketplace) 3. checkout http://svn.apache.org/repos/asf/jackrabbit/trunk 4. open /jackrabbit/pom.xml 5. open /jackrabbit/jackrabbit-spi-commons/pom.xml 6. click the "pom.xml" tab at the bottom of the POM editor 7. press Ctrl+F 8. observe delay
Thanks for the comprehensive set of instructions. I was able to reproduce the Find slowness (initial dialog comes up white, then paints after a few seconds). Will keep you posted on the investigation. BTW, are you able to provide the same reliable steps to get the tab slowdown? Or does that one happen only intermittently?
See also bug 380377 ,there's a profiler screenshot which can indicate the root cause.

(In reply to comment #4) > Thanks for the comprehensive set of instructions. I was able to reproduce > the Find slowness (initial dialog comes up white, then paints after a few > seconds). I just found out that it's the XML editor, not m2e, so the setup for reproducing can be reduced: 1. download eclipse-SDK-4.2.1-linux-gtk-x86_64.tar.gz , and 2. install "Eclipse XML Editors and Tools 3.4.1.v201208170345-7H7GFeFDxumUpsw5rgjWnKDrsz0p4ymwjQz00T2S" from Juno update site 3. create two empty XML files and haven them open in editors 4. open *any* dialog, e.g. find dialog (won't open in empty editor), or "About Eclipse SDK" 5. observe delay
Bogdan do you think this should be assigned to WTP? It would be great if they had some hint on what their mistake was, if any...
This is probably related to bug 385272.
Closing all XML editors returns performance to acceptable levels.
I a slightly different setup (using the m2e POM editor which embeds an XML editor), I can see the activation of the toolbar org.eclipse.wst.xml.ui.design.DesignToolBar (defined in org.eclipse.wst.xml.ui/plugin.xml) flicker for a while time. Maybe this helps finding the root cause.

Maybe this > helps finding the root cause. On a co-worker's machine I just observed two toolbar buttons to dance for the 30sec-or-so time of switching between an XML editor and a Java editor: one to toggle grammar constraints and one for refresh. Are those the same buttons you observed flickering?
x-ref: the buttons I saw dancing and the toolbar Tobias mentioned in comment 11 are the same as in bug 391868 comment 9.
Yes I feel the exact same behavior, It seems that when the XML Editor lost his focus the two buttons start flickering and it take almost 20s to Eclipse get get back to normal, this look like bug 391868
The fix announced in bug 385272 does work! I just downloaded http://www.eclipse.org/downloads/download.php?file=/eclipse/downloads/drops4/M20121107-1200/eclipse-SDK-M20121107-1200-linux-gtk-x86_64.tar.gz and tried to reproduce, but the dialogs now pop up without delay also after opening several XML editors. https://bugs.eclipse.org/bugs/show_bug.cgi?id=391868#c12 says the fix was provided by Bogdan, so now I'd be really curious what the problem was?
Fixed in M20121107-1200. E4 finally became a pleasure to work with :)
For anybody coming across this bug, explanations can be found in http://wiki.eclipse.org/Platform_UI/Juno_Performance_Investigation (as mentioned in Paul Webster's closing comment of https://bugs.eclipse.org/bugs/show_bug.cgi?id=391868#c48)
