TCP fix results

As everyone is very well aware of by now, I recently fixed a TCP problem at work. This morning I collected some before/after results.

512k streaming read throughput (higher is better):

         without fix   with TCP fix
single     154 MB/s       870 MB/s - 5.6x faster
1:1        480 MB/s      1954 MB/s - 4x faster
peak      1376 MB/s      2052 MB/s - 1.5x faster

So yeah, maybe you can see why I was excited!
