So today when launched MCM self updated to 2.18 (9618.773 - released on the 6th).

Now when MCM launches Listing the Library takes ~500 seconds to load. Previously it took 45-55 seconds. 1044 titles, 990 movies, 54 TV.

All my media is stored on a NAS. MCM running on a desktop with Gig wired connectivity. I can see while listing the library that network activity is very high. Averaging 200+ Mbps.

No other changes have occurred to my setup.

I couldn't find any changes listed relating to this update, hence posting this here first.

Try refreshing your cache in case there's complications with it. There's been no changes that should affect startup times and I'm not seeing anything myself using my own library.

I've now cleared cache - 400 seconds
Rebooted - 394 seconds
Cleared cache again - 389 seconds.

I still see a large amount of networking activity going on. Much more than simply directory listings would explain.

Is there an easy way to roll back to the previous version to prove if the version upgrade changed anything vs something I may have missed within my setup?
