You have too many non-Mac-native sharing service that are actually running, chewing through computer resources. even ONE such service, because it is ported form that other operating system rather than being re-written for Macs, punishes performance by searching through your files AND the files on the share NON-STOP looking to update anything that has changed the MOMENT it changes.
This convenience costs you Dearly. In my option, TOO Dearly. You should only launch these non-Apple sharing services when you want to store something, then quit immediately thereafter.
Mac Native sharing such as iCloud, uses The Mac File system Event store to determine in an Instant what has changed, so they do NOT need to search, and they do not punish performance.
