Just for fun. Tor would do both, compress and decompress. Well it's

Too bad. (for the network)

Sure when CPU is critical, more CPU cycles for other stuff hurt the exit.

I'll read it. Thanks.

The idea, don't know if the .txt went through (don't waste time with
reading it), contained that this would be done blindly, every traffic or
based on port, no data analysis.
I didn't thought compression would be considered as bad because it would
alter the traffic.
Thank you for explaining.
