webmail very slow and hangs

Postby bobtt » Fri Nov 29, 2019 12:00 pm

Hello

we have just migrated from 7.x to 8.8.15 using zextras

we are experiencing slow loading times which result in client timeouts while loading the webpage and while browsing, disabling memcached and proxy doesn't change anything, the latest update is applied


any help would be very much appreciated
