A lot of people say that lightweight desktops/distros help. Probably GNOME/KDE unnecessarily use your SSD, network, GPU and other resources even when you are idle, compared to using a minimal WM and only starting the daemons you actually need. I personally never tested it, and I can't find definite benchmarks that confirm and measure the waste.
