Re: [tor-relays] Bridge with iat-mode=2 very slow

[George Hartley via tor-relays <tor-relays@xxxxxxxxxxxxxxxxxxxx>]

This is to be expected, you get 100kB/s with iat-mode=2, and around 256-1024kB/s with iat-mode=1, however since most sites I load are just HTML/CSS with little pictures, it is no big issue.

I would consider taking the speed penalty for more protection (as a research paper also pointed out).

Greetings,

George

Hello everyone!

I run the obfs4 bridge, in the parameters I specify to use iat-modr=2. As a result, the bridge is VERY, VERY SLOW. Connection speed is on average 100 kb/sec. When I remove the iat-mode=2 parameter, the speed becomes 8-10 times higher.

I checked the processor load, it is at 3%, the problem is unlikely to be with the processor, the RAM load is at 20%. I can't figure out if this is expected behavior or if the speed drop is too significant. Please tell me, is this the normal maximum speed of the bridge with iat-mode=2 or can it be increased somehow?
