Catalina/Big Sur is too slow.

Hi. I updated from Catalina to Big Sur and my Mac became ridiculously slow. Reseting SMC/NVRAM/PRAM didn't help. I wiped it out and installed Catalina again. A couple of days later OS started to get slow again. Sudden and quite long spikes in CPU usage up to 90% make it impossible to work. Any help?
