Tobias PullsI evaluated using the first eight production servers from @mullvadnet running the new DAITA feature as a Windows user. The results are below. TL;DR: DAITA makes it harder to fingerprint web traffic but costs a couple of extra MiB of bandwidth and seconds of delay per website visit.

Rasmus Dahlberg@pulls interesting that congestion ends up causing noticeable delays!
@rgdd yeah, it has been discussed for a while, fun to get data on. Having defenses trigger small delays is more complex to get right in practice than just padding, but it seems to be worth it!
From the results I'm really happy to see that the impact is less than swapping to a server on another continent 😅 in a sense, it's less than an unfortunate single hop when using Tor.
