AFAIK, the Dalvik VM is currently an *interpreter*... running on an emulated ARM. Apparently the speed of the ARM is roughly equivalent to the 300MHz target device when the emulator is run on a modern, fast machine, so what you're seeing is probably something like the eventual speed of the device. It's going to be slow. When the JIT arrives it'll be much faster, but I think your only real hope for now is to use JNI. Unfortunately, JNI is totally unsupported right now so if you want to do it you're completely on your own. There's also at least one loader bug which means your code may not end up in memory intact. While you can hack it into submission if you're willing to risk it, it's most certainly not product ready... but it is possible. -- ┌─── ｄｇ＠ｃｏｗｌａｒｋ．ｃｏｍ ───── http://www.cowlark.com ───── │ "I have always wished for my computer to be as easy to use as my │ telephone; my wish has come true because I can no longer figure out │ how to use my telephone." --- Bjarne Stroustrup
