Receiving data is extremely slow, close to non-existing. This was first observed with Squid, but is confirmed by using the netcat utility: #> echo -e "GET /home/index.html HTTP/1.0\n\n" | nc www.itu.int 80 Disabling ECN doesn't help. tcp_congestion_control was set to bic and hybla - no change, too. This issue further has been confirmed on 2 seperate servers connected via 2 independent ISPs. Does anyone have a clue? Please include me on CC: as I'm not subscribed.

Thanks a lot. That was the thing I oversaw. Disabling window scaling solved the issue. ITU admins have been informed. Cheers, M. ^ permalink raw reply [flat|nested] 3+ messages in thread
