I think that precompiled Java code (using gcj) is often still slower than
byte code on a recent commercial JVM with JIT. That doesn't mean that it
isn't quite fast!
(_Years_ ago I made some simplistic tests showing that the C++ STL
containers didn't perform significantly better than the Java equivalents
when using a decent amount of initial JVM memory. Both sides have probably
been improved now.)
What is absolutely wonderful about precompiled, binary Java code is
integration with C, C++, ...! And then using gdb to debug it all!
