With these 3 patches applied, my throughput improved again. Using sftp with an
128 MB file, my transmit rate increased to to 1.5 MB/s. With tcpperf, I get 9.9
Mb/s - roughly the same.
I'm using the 'pid' rate-control method, which now stabilizes at a lower stated
rate than previously seen, but the throughput is higher. Curious.
