How much overhead can we expect from Tribler for 40 GB per day upload limit?

[absolutep]

I upload close to 40 GB per day whenever I have Tribler ON.

How much overhead can I expect if I am using only 1 hop?

Will overhead be close to what I upload, 40 GB approx.? Or will it be more than than?

Also, during this time I am RELAY Node for others - will it add to my overhead data?

I am not looking fir an exact answer but an approximation will be appreciated as I have changed ISPs and it has a limited metered plan only for now. Therefore, I need to be mindful of my usage of Tribler.

It's been a few years since we did the measurements. I believe anonymization roughly multiplies your bandwidth use by two (@egbertbouman please correct me if I'm wrong). So, say, 20 GBs out of your 40 GBs are torrent data: the rest is anonymization overhead.

Regarding relaying: correct, this also adds to your data use.

anonymization overhead

Can you explain what this is and what it is used for please?

Sure, we have a description here: https://www.tribler.org/anonymity.html (with the protocol-level specs here: https://github.com/Tribler/tribler/wiki/Hidden-Services-Specifications-for-anonymous-seeding). Essentially, there is a lot of cryptography going on, and that uses additional data and processing power.

The extra cryptography and processing overhead is understandable. I was not expect 50% of data would be overhead, it seems excessive if you are on a metered or limited data allowance.
