| Java Update! Wow...am I the first to post this? Anyway, check it in the S.U. "What's new in this version: provides improved behavior for applets in Safari and increased stability for desktop Java applications. Java 1.4.2 Update 2 also includes all the improvements from Java 1.4.2 Update 1. The system will be updated to Java 1.4.2 Update 2. If the system currently has Java 1.4.1, it will be removed. Any previous Java 1.4.2 installation will be completely replaced."

| It probably won't do. Apple doesn't ship a server VM which is a real shame as Apple's JVM is quite possibly the best JVM around in terms of integration with the host OS. |

| Well, this is quite a surprise. The little application I was testing was running about 1.5 seconds on average with the previous Java. This update 2 reduced the run time down to 0.5 seconds. For comparison, the same app on a 2.4GHz P4 has been running 0.4 seconds, and 0.1 seconds on a 3.0GHz P4. I need to try some other of my bigger, piggier Java applications to see if I see any noticable difference. I also have a less efficient version of this little tool I was testing with that might show a bigger percentage difference, too. |

| Are you benchmarking with the Server or Client VM? Also it's a shame that Apple hasn't updated the Java developer libraries yet. Here are some benchmarks that I normally run to gauge java performance on different platform. I normally deal with numerical apps, so these are representative of the performance I can expect to get from Java in these situations. Check out Scimark at http://math.nist.gov/scimark2/run.html and Linpack at http://www.netlib.org/benchmark/linpackjava/. Java's performance on OS X is still pretty dismal.
