Autocompletion and Typing Sluggish - PDT2.0.0GA [message #88621]

Wed, 07 January 2009 09:53

Eclipse User

I'm running Ubuntu on a dual-core laptop with 3GB of RAM.

When typing, Eclipse/PDT often hangs on attempts to show me auto-complete
options. It becomes unresponsive for a few seconds, then "works" again.

Also (related?) some times typing gets so slow that I'll be almost a line
or two ahead of the screen, and I need to stop and wait for Eclipse to
catch up.

I never had these sorts of issues with Europa/PDT1.

I edited my eclipse.ini file to increase memory - here's what I did:

-startup
plugins/org.eclipse.equinox.launcher_1.0.101.R34x_v20080819. jar
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
1024m
-vmargs
-Xms256m
-Xmx1024m

That actually helped, but has not solved the issue. When it's happening,
Eclipse is usually using ~300MB, so I'm not sure that increasing it
further will help (but I'm going to try ;) )

The project that I'm working with is not small - probably close to 4000
php files.

Anyone have any ideas?

Thanks
Tim

I'm asking, since we have some network performance issues:

The files are stored locally.

I've already increased the maxPermSize to 1500MB, and Eclipse/PDT is not
using anywhere near that, unless I'm completely missing some other secret
process :)

Thanks for the suggestions

How large are your files? Do they have many functions/methods in them.
One thing you can try is to turn code folding off. This will keep the
editor from trying to recalculate the code folding points in the file.

I doubt tha tthe maxPermSize greater than 256Mb is going to make any
difference in this.

Hey Dave -

Thanks dude. That seems to have done more than the memory allocation ever
did. Still not perfect, but a WHOLE lot better.

So what's the deal with this? PDT 1 never had this issue - though I
realize that the new one is probably a bit more intensive.

Yup - there's a crapload, though I don't know what's related.

One suspicious one that comes up a lot is:

I see that as suspicious because of the "caused by" having
org.eclipse.php.internal as the first entry in the stack. No idea if it's
actually relevant.

There are a lot like this too:

Ok, just happened - I was autocompleting a comment DocBlock when it froze
slightly, and this error was in the log.
