My Odroid HC4 ARM box holds up great for basic use. The only times I notice slowdown:

apt update/install
150k "rm" commands for 150k files*

*generated by rmlint. rmlint and fclones are the only file dedupers worth using. rmlint is conservative and probably the safest deduper on the market.

I feel like this rm job would be <1 hour on a desktop, but here it's going to be like 24 hours.
