Does wireguard have a noticeable overhead wrt data size compared to a unencrypted connection? I was thinking of setting up it on a small RPi-Like board at home, then on the laptop I carry around (when the lockdown is over). The purpose would be connecting to the Internet through the home broadband public IP which could be handy. However the laptop connects through a metered 4G connection which, although the data cap is more than reasonable, raises some concerns should the encryption require a lot more data than normal.
- nightfly 7y agoI just sent 200MiB of zeros over my wireguard connection to my VPS and my transmit counter on my wifi card went up by 238MB. Vs sending 1024MiB over just wifi to my Pi where the transmit counter went up by 1.04GiB.
- squarefoot 7y agoThanks, looks good for mobile metered connections too then.
- afiori 7y agoIs this one of those cases where is Wireguard implemented traffic compression as a "feature" it would become a huge security flaw? I remember hearing that this is the case for naive HTTPS compression, but I never properly had insight in the how.
