Zram likes spare ticks as the compression even though light creates load. If ram is a problem and its forcing disk based swap then yes zram could help as your swap is mem based rather than flash based.
If you are just maxing out on cpu load then zram could actually just add a little more load. Don't use zram-config-0.5 as its an awefull implementation try https://github.com/StuartIanNaylor/zram-swap-confighttps://github.com/StuartIanNaylor/zram-config
