good match for the wireless environment.<br>

Wireless access points or devices with too much buffering memory make<br>
the problem worse.  A case of more not being good.<br>

Former OLPCer Jim Gettys warned us about bufferbloat years ago.<br>

I'd like to hear from anyone deploying the new BBR congestion-base<br>
controls, which should be available in 4.9 kernels.  It is a<br>
server-side feature, so there's no great need for it in laptops that<br>
