[Java-gnome-developer] Memory Usage for small app

[Neil J. P. <njp...@gm...>]

Hi,
	I was inspired by an OSNews article yester which pointed out developing
gnome apps with java. I follwed the examples and all worked fine (with a
little tweaking), the question i have is that a very simple application
compiled with gcj takes up quite a lot of memory:

Total : 55.1 MB
RSS   : 22.1 MB
Shared : 16.3 MB

I just wanted to now if this is normal, and/if there are any option when
compiling that can help.

Using FC4T3 java packages,
the gcj commands were:

gcj --classpath=/usr/share/java/gtk2.6.jar:/usr/share/java/gnome2.10.jar
\:/usr/share/java/glade2.10.jar -l gtkjava -l gnomejava -l gladejava -o
ExampleGNOME --main=ExampleGNOME ExampleGNOME.java

gcj = 4.0.0-8
gtk-java = 2.6.2-3
gnome-java = 2.10.1-3
glade-java = 2.10.1-5

attached the source of the small program.

Thanks,

It would be interesting if we'd create an example in C and Java, and make a comparison. Let's put
this in our TODO list. I think those numbers are "normal": gtk itself takes lots of memory, and
there's also the VM (mainly the garbage collector). Currently JG is going through a major memory
management improvement, though.

Cheers,
J.V.
