Mobiian Community edition issue after spalsh screen

[wibble]

running mobian nightly 20210301 on PP KDE 3GB, and works great so far! i tried FDE from alpha3 before but i have the feeling the encryption makes everything a little slower.. can anyone confirm?

Once you boot a phone and decrypt it using your decryption code your drive is decrypted. There is no speed difference. It doesn't encrypt the drive again until you shut down the phone or reboot so other then boot decryption time there is no speed difference in actually using the phone.

That seems odd and unusual - AFAIK the pinephone doesn't have self-encrypting eMMC so I'd expect the CPU to be doing the encryption and decryption on filesystem operations. Whether there's a performance hit depends on the relative speed of the (hardware accelerated?) crypto operations and eMMC access.
