Earlier quoted context omitted.
seems inherent - servers operate in rounds and each round carries legit traffic plus enough noise to allow traffic metadata to drown in nothingness and forward it to a whole server chain to avoid an adversary to control all the servers, so as you scale servers need more time to forward and mixin traffic
Could someone much smarter than me do some napkin math and figure out roughly what kind of tradeoff in security you make by limiting the noise? 20-40 seconds is fine if you are releasing NSA secret files and want the chance of metadata discovery to be But it's too much to use as a regular form of conversation between average parties who just want to set a precedent that all conversations by default should be un-monit…
