Before I file this in bugzilla, I wanted to check if it's just my problem ... Lately, in Eclipse (3.4.1 on Fedora 10), I've been noticing that it takes several seconds to open a new editor. So if I click on a Java source file (in Java perspective), the new tab appears immediately, but it takes several seconds for the actual editor to finish rendering. In the meantime, the tab just says "Java editor". Similar things happen with the Ant buildfile editor.
I have several third-party plugins installed that I don't want to remove unless I have to, which is why I wanted to check first -- is anyone else seeing similar symptoms?
Thanks,
MEF

It depends on which Java you have installed. Try this:
$ alternatives --config java
There are 2 programs which provide 'java'.
Selection Command ----------------------------------------------- *+ 1 /usr/lib/jvm/jre-1.6.0-openjdk.x86_64/bin/java 2 /usr/lib/jvm/jre-1.5.0-gcj/bin/java
If you're on x86, select openjdk. If you don't see openjdk,
yum install java-1.6.0-openjdk-devel

No. This should be fun to track down ;)

I just tried with a fresh ~/.eclipse directory and a fresh workspace -- and with both OpenJDK and GCJ -- and it still takes a very perceptible amount of time to open files. Here's a video: http://www6.informatik.tu-muenchen.de/~foster/eclipse.ogg
Using the fresh ~/.eclipse should have got rid of the third-party plugins, but I still have a few Fedora plugins -- CDT, mylyn, and subclipse. Maybe those are an issue ... can't test much more at the moment but I'll fiddle around later.
Not much help yet, unfortunately. Maybe I should look upstream and see if anyone's reported similar issues.

Hmm. What about opening a second .java file? Once the JDT UI plugins are (lazily) loaded they should be much faster.

That's correct.

Yeah. It would be nice if we had an easy way to profile this. Other than the TPTP (eclipse.org/tptp) profiler, I can't think of one OTTOMH. It would be an interesting project to see what's the best option out there.

I thought that would be true too, but unfortunately it doesn't get much faster when opening subsequent files. And all editors seem to be equally slow, including the plain-text editor. I'll try this at home tonight on my laptop and see if it happens there too; might be something weird on this computer.

Update: turns out it's a problem with GTK printing (and possibly a slow-ish print server on my local network). The problem goes away when I do either of the following things: - add -Dorg.eclipse.swt.internal.gtk.disablePrinting to eclipse.ini after -vmargs - remove the ServerName directive from /etc/cups/client.conf
More details in https://bugs.eclipse.org/bugs/show_bug.cgi?id=153936
Just in case anyone else sees this issue ...

Thanks very much, that was a real mystery.
http://bugzilla.gnome.org/show_bug.cgi?id=346903 seems still to be open, but there are patches.
