Description Tim Lebedkov 2006-04-17 18:18:20 UTC
./nbexec --jdkhome /opt/jdk1.5.0_06/ --userdir /home/tim/.testnbplatform

java uses about 40M and only shows an empty window.

15M should be probably enough for this.

Let's evaluate what is the lower bound by running simple Java app simulating the
same UI. Then we can better tell what can be appropriate for NB platform
baseline footprint.

Some results when trying with dev build (2006, Nov 23). Platform without any
additional modules, no custom configuration just built with build-platform.
JDK6b104 (32-bit), Linux FC4 x86_64

RSS of process is 41MB, 
PermGen: 12MB commited, <7MB used. here we can safe but soon after startup it
would grow with new loaded classes.
Heap: 6MB commited. This is not much IMO.

Now RSS for couple of other apps from JDK demo set: Notepad 24MB, Java2D 37MB,
SwingSet2 54MB!. If we compare size of JAR files for these apps then I'd say it
is not bad.

I am not sure what is the expected state. OK we want lower memory footprint but
this one bug sounds too general. I prefer more specific problems.
