Re: [PATCH] Make CUBIC Hystart more robust to RTT variations

Hi Lucas,

The current packet-train threshold and the delay threshold have been tested
with the bandwidth ranging from 10M to 400M, the RTT from 10ms to 320ms, and
the buffer size from 10% BDP to 200% BDP and they were set conservatively to
make it work over the network with very small buffer sizes. I will recreate
your setup and check whether the current thresholds are too conservative and
will come up with the patch.

I'm surprised. It's possible that a seemingly unrelated change broke it,
but it was already broken for me on 2.6.32.
I can provide access to the testbed if you want to run tests on it.
