RC1 still a bit slow at times.. [message #249082]

I notice several times in a session over a period of hours, that Eclipse
just sort of takes over the cpu. For example, I'll open a file to start
editing..it opens. Then when I click in the editor it just seems to hang for
a minute or so. Finally it comes back. I'll expand a project, then shrink
it, and it suddenly just seems to hang. Even clicking on other running apps
just seem to flash their taskbar button and not bring them forward. I am
guessing the GC is running? But I have 1GB of memory!! It shows that I have
over 600MB free memory, so I can't imagine why this is?

C:\java\eclipse\eclipse.exe -vmargs -Xverify:none

That is my start sequence. Should I add anything to increase memory? I
actually thought I had the xMx argument, but not sure if that is needed now?

But this still doesn't fix the problem why eclipse slow starts eating and eating memory..
When i start it first and it si completely loaded and the workspace fully build it uses this:

[Full GC 42610K->30398K(64960K), 0.5407743 secs]

so after a GC it only uses 30MB with a total heap of 64 (the size i start with)
But after a few hours this is multiplied by 4 (uses mem and heap size)
I do find this a bit strange.

It is piggish with memory, but RC1 is much improved for me in that
regard, and I think that it is one of the issues they hope to address
prior to the final release.

You'll still always need the -vmargs -Xmx256m (change 256 to whatever
maximum heap size in megabytes that works for you) if using the Sun VM (at
least for version 1.4). We have asked for the default to be increased but
currently the argument against it is that the option is VM specific and they
want to be VM independent, and also that RCP applications might not need
more than the 64M default maximum. See:

how does one find out what this is set to (in eclipse) and how does one
change it?

does anyone know what a good maximum setting is as a function of physical
ram size?

thanks

It should rather be a function of the number of opened projects you want
to have, a function of the number of objects in your java model, the
needs of the plugins you use.
Alternativly, you might find useful the MemoryManager plugin (see
eclipse-plugins.info)

It is set on the command line (-vmargs option) when invoking Eclipse, not
inside Eclipse. You want to set it as small as you can get away with without
excessive garbage collection. The default for Sun's JVM is 64M. The Eclipse
3.0 IDE needs at least 128M, and for my mix of work I use 256M or 300M.
YMMV.

So they keep the default where it will cause problems for the majority.
Interesting choice.

Interesting that there wasn't a bug report for it. So, I created one.
See https://bugs.eclipse.org/bugs/show_bug.cgi?id=66341 and vote for it.
