Re: [udig-devel] render performance

[Vince Darley <vince.darley@xxxxxxxxxxxx>]

I've got profiling tools in Eclipse, but can't even download the sources to 
udig to even begin to try that. The developer 'quick start' instructions 
fail at the second step:

E:\Apps\udig>svn co http://svn.geotools.org/udig/trunk
svn: PROPFIND request failed on '/udig/trunk'
svn:
Could not open the requested SVN filesystem

--

Can I ask whether, in the few seconds it takes to render on your machine, 
you see progressive rendering -- on mine the many dots appear progressively 
(in waves, it seems, so not at a constant rate), and it takes some 10 
seconds before all of them are drawn.

cheers,

Vince.
