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!
