I definitely noticed the performance boost on my Pixel 8, for some reason it seems to really not like wireguard-go, it struggled to pull even 100mbps, maybe something unoptimized on Google's custom hardware. With the new GotaTun version I can pull 500mbps+, though unfortunately it also seems to have introduced a bug that randomly prevents the phone from entering a deep sleep state, so occasionally my battery will randomly start draining at 10x normal speed if I have it enabled until I reboot.

I'm surprised by this comment. I have wireguard on 24/7 on my shitty Samsung A5 and it lasts forever. By comparison the Pixel 8 is a beast. Sounds like an Android bug more than wireguard.

Pixel 6 here. Vanilla wireguard app. It sucks the life out of my phone and nearly halves the already half-life battery (thanks Google for your crappy OEM producers!)

What app are you using?

Tharre|2 months ago

Android kernels 4.19 and higher should all have support included for WireGuard unless the OEM specifically disables it: [0]. The Pixel 8 ships with the android 14 6.1 kernel so it most definitely should have WireGuard kernel support. You can check this in the WireGuard app BTW, if you go to settings it will show the backend that's in use.

Kernel support should have no bearing as the apps are purely userspace apps. You can use the kernel mode if you root the phone, but that's not a typical scenario.

Same behavior on raspberry pi 5. Might be just lack of arm optimizations.

It's very likely that VPNs like this are not CPU-bound, even on somewhat whimpy CPUs. I'd wager even some microcontrollers could sling 500megabits/sec around without trouble.

MTU strikes again. 1320.

Why 1320 and not larger?

Oh, this is the reason the Mullvad app on my Pixel 6a was suddenly able to connect in less than a second where before it would take 5-10 seconds, nice!

I think the problem is on the Android side. I noticed the same behavior with ZeroTier and even with MizuDroid, all totally unrelated.

Do you have wireguard keepalives on?
