I'm a proton mail user, and recently started noticing performance issues while opening my inbox, and read messages.

If I check the load, at least 2/4 cores are in use when proton is opening a mailbox or message.

Is this normal? Is there anything that can be tuned to improve performance on the Pi; so it is not so impacting?

I have a RaspBerry Pi 4 with 8GB ram.

I would say if it hadn't happened until recently, and you changed nothing (that





































you're aware of) then maybe it's not normal.
I know that proton mail uses encryption but I assume that is server side and not on the client? Client to Server is TLS encrypted, but the pi should handle that no problem.

Questions running through my mind are;

1. Are you using a web browser version or is there an app that you're using?
2. If browser version, what browser are you using?
3. If you run htop or another process viewer do you notice any other apps behaving oddly?

Dunno if this helps or not, but it's me thinking "out loud" lol

Using web browser, viviadi. http shows the browser, systemd-timesyd, systemd-udevd as the top processes.

I had forgotten they have desktop apps. I normally use web, but I'll see if they have a raspberry pi app; and see if the performance is difference.

Thanks for the feedback.

Ah cool, well if you notice much better performance with the desktop app, then I would say that something is up with the browser you were using prior, if the same performance impact is noticed, then perhaps it's something else causing the issue and the symptom just manifests itself with proton mail?

Well they don't have an app for RaspPi. They have deb file but think it is probably 64-bit and not arm.

So I downloaded the rpm file, and installed it on my VPS, (Rocky Linux) and displayed back. It is not ideal, but does out perform running it through browser on my Pi :-( Kinda sad. But I guess the encryption/decryption work must


































be too much for it.

The displaying back is working okay. But I started looking at things on my Pi. I turned on temperature reporting in htop. And saw the cores were like 80C. I'm like that seems a bit high.

Started reading about others moving swap off SD card, and onto USB stick to avoid wear-n-tear on sd (and os disk), and usb stick can be easily replaced. The swap by default is on 100M and I have a RaspPi 4 with 8G. So seems a bit small also for the amount of ram.

So, I brought a usb fan to blow on the unit; and setup 8G swap (which I haven't seen it use yet) and thinks are working better. I have temp down to 5xC rather than 8xC . So I think my fan on the heat sink wasn't doing it's job (not running when needed).

We will see how the story continues ...

Ah this is some good investigative work, nice job.
Hopefully that will solve it entirely for you, sounds like you nailed it.
