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

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?
