what commands can I use to benchmark my cpu?

hardware is a nuked MacBook Pro, Intel Core i5-4278U @ 2.60GHz, model A1502 (EMC 2875), Retina Mid-2014 13" with debian 12.5 live xfce installed (I couldn't fully install any of the netinst candidates).

As posted before, I consider this a really slow notebook and to compare and give you an idea, I need benchmarks. Download speed works fine via USB-tethering with an android device but the installation speed is ridiculously slow. System reacts very slow after entering username and password as well.

I'll try gnome and cinnamon later and compare.
