I’m talking about the official one; updated now from the OSMC update from Kodi 16 to Kodi 17. Even if the archive_cache is in place, the UI navigation it is not immediate and I could say regressed. The other RPI with the test version of OSMC same behavior.
As I wrote in the posted links, when a video is terminating from an addon (youtube in my test), the system still thinking a while instead to give immediately the last menu when the video was selected.
This kind of slowness reflect the general performance of this new version.
I really hope that these performance issues will be fixed soon.
