Thanks for all your answers guys! Now i know that i'm doeing good running bridges in different iat modes. Actually I'm running 4 bridges, and two have iat_mode set to 0 and two others set to 1 and 2 respectively.
I also have a question about bridges speed. It seems that when I do use of my bridge (that is in same network of my PC) the connection is too slow (~1Mbps using relays in a circuit that clearly (by seeing it in tor metrics) has high bandwidth). I do use it as a guard relay. But, when i disable the settings, using the same circuit or an very similar one I can see that the speed bumps to more than 4 Mbps. Is there any optimizations that I can do in my bridge relay? I have 20 Mbps uplink and 200 Mbps downlink here. Set my speed setting to 10 Mbps maxium in torrc. I can also see that bridge is not overloaded (no high cpu usage and low number of connections around 180 for now).
Best regards,
Luiz

If you run more than three bridges, run an even distribution of bridges with iat_mode set to 0, 1 and 2, if you run only three bridges, one with each setting, if two, then 0 and 2, if only one, run it with 2 due to the lack of bridges supporting it, et cetera.
That's how I would handle it..

Thank you for running obfs4 bridges with iat_mode != 0, only very few obfs4 bridges support the additional traffic obfuscation in both directions. Kudos to you my friend.
- William Should I take this as a recommendation to update my bridges to support iat_mode=2.
Cheers.

Hi All, I work with time and frequency references and run some tor bridges. What is the objective of "iat_mode" setting? Is an good timming reference important for this setting? For now, i'm adminstrating 3 briges, one with iat_mode=0, iat_mode=1 and iat_mode=2. Could you explain or forward me to some reading about it? Best regards, Luiz Sent with ProtonMail Secure Email.
