Hi, Please review my patch for 9006475 at: http://cr.openjdk.java.net/~ceisserer/9006475/webrev.00/
Before this patch we were calling the native method XRenderRectanglesNative() even in the case that there was only single rectangle to be rendered (which is the case for Graphics.fillRect). As XRenderRectanglesNative() uses GetPrimitiveArrayCritical, this caused high overhead for small fillRect() oerations. With this patch we call renderRectangle instead, which passes the reactangle's coordinates down using JNI function parameters. On my private Laptop this improved throughput of 1x1 fillRect calls by a factor of 3. Thanks, Clemens
