I guess you're asking for small images and the raster data you have on the backend is small too. JAI does make a difference also for vector data, up to two times, but only if the request is fast to start with. The benchmarks normally have less layers and I guess simpler styling, as the responses come back in 50 milliseconds or less (no kidding), though normally all the source data is cached in memory by the operating system. Under those conditions using native JAI makes the difference between 100ms and 50ms, thus twice as fast. Cheers Andrea -- ------------------------------------------------------- Ing.
