I am developing an Eclipse RCP application in which I need to plot diagrams. I am using org.eclipse.draw2d library for ploting figures. This is a multi threaded application supporting multiple views and painting operation is performed by one of the thread asynchronously (using IProgressMonitor).
If a large number of figures(around 200) are plotted multiple times(about 8 - 10 times), a considerable amount of delay is observed while painting. This delay increses further on subsequent paint operations finally the application hangs.
I have checked the application performance using VisualVM profiler and it seems that there is no memory leakage. From the profiler we foound that this particul;ar thread -> "org.eclipse.swt.internal.gtk.OS._gdk_draw_layout_with_colors" is taking a bit more time.
Please provide me some pointers to avoid this delay.
