    eBook (PDF)

    Mostly marketing, with some technical information

    This mostly a marketing book trying to sell you Java technologies. It has a few technical information here and there, but you'll need to go through a lot of fluff in order to find it. It's okay to start with it if you have no idea about performance optimizations in Java, but if you have a small idea, then reading articles online will probably waste less of your time, and give you more up-to-date information, with (hopefully) less Sales bias.
