Hi all,

    I use GeoTools 8.0M4 to load a shapefile contains about 10,000+
 geometries (each is a multiline). The code is just like the demo in
quickstart. But I found the rendering is a little slow, especially when I
zoom in/out or drag the map, and even sometimes the rendering couldn't
completed (leave some blank area).  What can I do to optimize the
performance of rendering, or the demo is already the best solution? The CPU
of my PC is Core Duo E6550, the memory is 2G, and the graphics card is ATI
Radeon HD 2400.

    Thanks and best regards!
