Genreal operation and Playlists very slow

I’m using a Mac running Os Catalina 3.5 GHZ Quad Core i7 32 GB DDR ram Late 2013
Roon has become neigh unusable - random closings and very very slow when searching for tracks and the fan kicks in quite often
I have even given it serious thought in going back to I tunes and currently looking at MediaCenter 29.

I have rebooted several times and have just updated to Catalina - although the issues are not new

Would appreciate any thoughts
