One big reason is that a lot of time is spent in system libraries, which are written in C/C++. I believe in the original talk on Dalvik, it was indicated that 70% of the time was spent in non-interpreted code. You also have to remember that Dalvik has a JIT compiler and now an LLVM based runtime (still in development, it seems), so the impact from Java is less than you might think.
