okay, I just did some quick and dirty (only one file at -q 5) benchmarking with some oggenc compiles:
oggenc RC3 ICL5 (alex):

As I said, this was just a quick and dirty test and I will test more (more samples + a Linux gcc 2.95 + 3.1 compile) tomorrow (when I'm not as drunk anymore).
The only thing that really became clear with this test is the massive speed increase in pre-RC4.
