The BIND DNS server has already been deprecated and removed from Plesk for Windows.
If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release. -
The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

@ghazestor We did not experience any increased CPU total usage. Based on your settings the free workers are not the ones to blame. The speed increase comes from the dedicated master processes per website having their own OPcache. This can improve PHP performance dramatically by storing precompiled script bytecode in shared memory for the PHP handler. This removes the need for PHP to load and parse scripts on each request. This normally even brings CPU usage down. Of course you pay a price for that: the memory usage increases based on the settings for [opcache] in the php.ini. The shared FPM application handler on the other side never has really a chance to cache PHP scripts very long as the different websites kick each other out of the cache again and again - at least with the standard [opcache] settings in Plesk. Furthermore the PHP function opcache_get_status has to be disabled for obvious security reasons.
