Hi, I have made important modifications in EditTransaction class in order to improve performance. 1 - I have replaced most Lists by Sets and Maps avoiding the List.contains() method which is far too slow. 2 - I have removed geometry cloning in createFeature and deleteFeature methods, avoiding time and memory consuming operations.
I cannot say I'm 100% sure cloning was useless in every case, but I made a lot of tests to checks it does not beark anythink. Please, report any suspect behaviour (from next NB). You'll see the benefits if you compare the following operation which uses a undoable transaction : Explode a multigeometry having 180000 small polygons Before 2mn 50s - memory increase from 160Mb to 425Mb After 10 s - memory increase from 160Mb to 260Mb Michaël ------------------------------------------------------------------------------ BlackBerry® DevCon Americas, Oct. 18-20, San Francisco, CA http://p.sf.net/sfu/rim-devcon-copy2 _______________________________________________ Jump-pilot-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/jump-pilot-devel
