how to read images fast with Apple Java?



I've got an application which has to read 2550x3300 24-bit PNG images
into BufferedImages in Java, on OS X 10.5, and I'm wondering what the
advice of the community is on how to most quickly read each image.

Currently, I just call ImageIO.read() and let Apple's code "just do the
right thing".  Is that smart?  It seems to take 200ms or so to do this
on a 3GHz Xeon.  Is there some hardware-accelerated path I should be
using (without writing Objective-C code, please)?

Bill
