Re: [udig-devel] render performance

Points do not use the optimized shapefile renderer so are slower compared
to lines so that may be the problem. I had thought that the normal
renderer would be good enough for points but perhaps I was wrong. I tried
it on a 1.6 Mhz AMD and it took about 7 seconds. I admit it is a little
slower than I would like and I'm sure it could be improved down to about 4
seconds without too much difficulty. Is that what you'd like?
That would certainly be good! It would also be good to have visibility of
what changes were required to provide such an improvement (i.e. I was not
aware there was an 'optimized' and 'unoptimized' shapefile renderer), so
that we can be aware of that and potentially contribute improvements if we
do further work in that area ourselves.
If so please file a bug report with the JIRA bug track, (or ask me to)
I just filed: http://jira.codehaus.org/browse/UDIG-549
