"We rolled back the behavior where it throttles traffic to not exceed the limit due to overhead. It was bugged and too close to release. Now it behaves more like 1.8.x." From 1.6.x-1.8.x I had to set a 6 kB limit for my 1mb/128kb limit to be able to download with near maximum speed and to be able browse webpages. I tried build 17624 yesterday. I kept settings from 1.8.5 didn't change anything but it wasn't working anymore. The webpages were hardly loading, the download speed was fluctuating and rarely neared the maximum. So it doesn't work like 1.8.x. I switched back and everything was normal again.
