ah, just as a side note when doing such micro-benchmarks:
you should always use the result in some way (e.g. use it in a
calculation), otherwise the JVM may optimize it away.
I changed the code to something like this:
long d = 0;
start = System.currentTimeMillis();
for (int i = 0; i < FACTOR * REPS; i++) {
encoded = IHarderBase64.encodeBytesToBytes(data);
d += encoded[i % encoded.length];
}
printEncodeStat(start, data, d);
