Hi, Jochen,
Thanks for pointing out that method. I was looking for a static
method. I didn't expect it to be an instance method! Anyway, now
that I've found it, ws-commons-util is the winner!
[16.203 seconds] ws-commons-util THE WINNER!!!!
[21.946 seconds] not-yet-commons-ssl
(For some reason not-yet-commons-ssl starting running faster....
weird. But sun, iharder, and openssl didn't change!)
Here's how I used ws-commons-util:
FileInputStream fi = new FileInputStream(args[0]);
InputStream in = new BufferedInputStream(fi);
InputStreamReader reader = new InputStreamReader(in, "US-ASCII");
char[] buf = new char[8192];
Base64 b64 = new Base64();
Writer w = b64.newDecoder(out);
long start = System.currentTimeMillis();
int c = reader.read(buf);
while (c >= 0) {
if (c > 0) {
w.write(buf, 0, c);
}
c = reader.read(buf);
}
long duration = System.currentTimeMillis() - start;
yours,
Julius
