Java .next - some notes

One issue with Java SE 6 is its size. It can be as large as 10-11 mb to download. Once downloaded it expands to 40+ mb. Which takes time to unpack. Another issue is the startup times for applets. The Java team are working to remove these issues in the next Java release. The Consumer JRE will address these items among other things. -- Startup. Coldstart is the real culprit. First launch after reboot must load a lot of classes. The solutions is QuickStarter. The idea is to pre warm the disk cache by loading minimum component at OS startup. -- Install/Download time. 10+ mb download. Unpack to 40+ mb for just rt.jar. Solution is to download Java Kernal only. Stream down the rest of the platform in the background as needed. Preliminary results show that Helloworld just requires 2mb to execute. LimeWire needs < 4 mb. Should be available 1st half of 2008. Early access now https://jdk6.dev.java.net
