Here’s a couple of pointers to get started:
- The Arch Linux Wiki is full of excellent information. It’s not for beginners, though.
- Run
top
in your terminal to see what’s taking CPU. - Run
top -o RES
(or what’s easier, runtop
and then pressM
while it’s running) to see what is taking up RAM.
… though unfortunately, it’s mighty probable that the only significant consumer of memory and CPU is your browser. Get uBlock Origin, it helps web pages be lighter and eat less resources. Don’t open too many tabs at once - learn to use bookmarks efficiently, instead (folders, bookmarks toolbar and whatnot).
I’m using VNC over an SSH tunnel. TigerVNC’s
vncviewer
even has the-via
parameter you can use to make creating the tunnel seamless.
