Open activity monitory and sort by bytes written. Unless the process is gone it should show you.

Is spotlight impacting performance? I don’t notice any performance loss while indexing on my iMac. I would just leave it if so. It’s vastly less than my girlfriends laptop with Windows 10.

Do you have Time Machine running?

Windows absolutely has excessive disk writing, it’s done so since the 80s
