Using build I20050527-0010. I want to import existing project in my workspace. So, I use Import wizard -> Existing Project into Workspace... Then I want to Select root directory and click on "Browse..." button. Folders hierachy of my box appears in "Browse For Folder" dialog, but when I try to expand one, it takes several seconds before display the expanded folder (between 20 and 25 seconds) whatever the number of sub-folders to display... I got no problem with windows explorer which displays sub-folders quasi instantaneously... I have no other processes running which can explain this slowness. Here's a VM snapshot which s the same even repeated several times: Full thread dump Java HotSpot(TM) Client VM (1.4.2_04-b05 mixed mode): "Worker-61" prio=5 tid=0x042f4ed0 nid=0x224 in Object.wait() [635f000..635fd8c] at java.lang.Object.wait(Native Method) at org.eclipse.core.internal.jobs.WorkerPool.sleep(WorkerPool.java:167) -

The file chooser dialog is owned by SWT. Punting for comment.
I've seen this before in other applications that use the native directory dialog. Not sure this has anything to do with SWT.
Haven't seen this effect outside of Eclipse (but then again, I didn't use much other software lately ...). Interestingly, if you switch to a different application and then back, everything is fine (folder expanded really quick). Otherwise, it takes a really long time to expand a folder, while the cpu is at 100% (javaw.exe is using all of it). I just setup a new laptop, and I have the effect right away. Isn't there anything that can be done?
I also have this same problem. I have a 1.7Ghz laptop with 1G of RAM, and I'm not running anything else of consequence besides Eclipse. All of the other eclipse functions run plenty fast, but this one dialog is inordinately slow. Note that if I browse for a file the UI is very quick and responsive, but if I browse for a folder it is very slow.
I am new to this. This problem is very irritating. When can we expect a fix?
Can you guys try the latest and let me know whether it is fixed? There was a bug in this area (around M4?) that caused the badness. I can't find the bug right now ...
I still see the same bad behavior on M5a.
Most of the time it is fast now. Sometimes slow. Where can i see if i have M4 or M5a ??
It's OK for me with build I20060307-1315 :-) It's now quite instantaneous to display subfolders. I seldom got a longer time to open it (around 1 or 2 seconds), but nothing really irritating... So, I consider this issue as fixed.
Ok, marking WORKSFORME because I can't find the original bug to mark it a duplicate.
