This is interesting. Could you check other speeds too (50 kB/s, 100 kB/s)? > Full dump, from SYN to FIN, can be found below.

This should not be the case. http://obscuredtzevzthp.onion has comparable download speeds, where I easily get 600 kB/s, but cannot see any interrupts. I conclude it is either that particular HS software configuration or attack on that particular HS. -- tor-talk mailing list - tor-talk@lists.torproject.org To unsubscribe or change other settings go to https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-talk
