300+ms of hotel wifi bufferbloat - peaking at 1.5 sec!

While I agree that upload speeds aren't great, it doesn't mean that the 
buffers aren't big. Buffer sizes of the order of MB's are uncalled for 
at the edge, unless we're talking really high speeds. The miniscule 
performance increase for single TCP flows doesn't really justify the 
potential increase in latency for everyone else.
