NC 25.0.1 upgrade

Am running 24.0.7, wanted an upgrade to 25.0.1 which failed with a hang.
Ran “PHP occ upgrade”, which worked.

However, it appears NC 25 is much slower than NC24 when it comes to reaction time. And some apps are not working correctly, like Notes, Short Notes.

Any ideas, assistance or help?
Thanks
V.
