N 2004 Jun Java vs C++ benchmark (updated)
N 2004 Jun Kirk's analysis of the (lack of) usefulness of the Java vs C++ benchmark
N 2004 Jun Java3D source code is being released. The resulting slahsdot discussion includes performance considerations, but I don't know why I continue to list slashdot discussions here because there is just so much noise in there compared to the very few items of useful info.
N 2004 Jun The slashdot fallout. This has got to be the funniest Java vs C++ discussion I've seen. The C++ lovers are desperately crying "unfair, we have to manage memory manually and you don't". Their suggestion to even up the score - add in lots of calls to System.gc() to slow down Java (in case you don't realize, Java does reclaim the memory without calls to System.gc, adding calls to System.gc just slows down how it does so). Further complaints all seemed to boil down to this being a benchmark biased to Java. But strangely enough it wasn't 3 years ago when the test against the then JVM version showed C++ faster. Probably some valid comments somewhere if you really dug amongst the drivel.

N 2003 Sep Interesting discussion about Java games, slight reference to performance: "I'd especially like to ... turn on incremental and concurrent collection and adjust heap size min/maxes [at run time], and I'd really like to be able to specify a millisecond-resolution throttle on concurrent collection activity and ask it to make an incremental collection at a specific point in time, during a SwapBuffers. This is pretty important. I do other things besides games with Java - I'm doing something for Abu Dhabi TV right now using the LWJGL; they need a caption-generation system. Unfortunately, as it's live TV I'm not allowed to skip a single frame ever. It's pretty scary having to worry about GC occurring. And it's very noticeable when it does."
