Re: [cdt-dev] CDTProject creation scalability issue
|
To answer all the questions that came up:
1. Yes, I really meant 18GB, not 1.8.
2. Java version:
java version "1.5.0_06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05)
Java HotSpot(TM) 64-Bit Server VM (build 1.5.0_06-b05, mixed mode)
3. I kept trying bigger values to avoid out of memory errors. I now invoke
eclipse like this:
eclipse -vmargs -Xmx4096M -Xss512M -XX:MaxPermSize=512m
Thanks,
Larry.

Did you set –Xmx to a really big number?

I imagine you meant 1.8GB. The most I get out of the windows xp box is
1.6GB. I dont run out of memory when just creating projects, but do when
I have other plugins that do tasks prior to the project creation and in
my scenario i cant afford more than 300MB to be allocated for project
creation.
Furthermore I must mention that in my scenario these are empty CDT
Projects (atleast for the time being).
I am still trying to understand why project creation requires more
memory than a restarted workspace that contains these created projects.
Cheers,
RB.

I can't speak to that many projects, but I can provide a data point for
scalability. I'm using:
CDT Version: 4.0.0.200706261300
Build id: 200706261300
on
Eclipse SDK Version: 3.3.0
Build id: I20070625-1500
I have three projects, 2 C++ and one Java.
The 2 C++ projects each have roughly 900 indexable (source and header)
files totaling ~ 500K lines of code. The java project has about 400 java
source files.
With this, eclipse has a VM size of roughly 18GB and a RSS of > 300MB.
I have had to constantly increase the size of the Perm alloc area to avoid
running out of memory.
Anyway, just a data point for you to use as you look at memory footprint.
Thanks,
Larry.
