I had an Aspire One D270 laptop with a 32-bit Intel Atom CPU and 1 gigabyte of RAM, so I installed Debian with Xfce on it, but even then it’s running way too slow.
Is there anything I can do to make the laptop faster and more responsive given its limited memory?
First install an SSD if you haven’t already. Next install ublock origin in Firefox ESR and tighten down the security settings to max plus turn off all telemetry, studies and other “features.” Don’t use a Mozilla account as that adds overhead.
It still will be slow but it should be usable with a few tabs. Do not try to do video playback as the old GPU doesn’t support modern video formats so the CPU ends up decoding it all.
