Maybe it's just me but since I've upgraded to Mac OS Mojave 10.14.4 running Parallels Desktop 14.1.3 on a 2018 Mac Mini, any Windows 10 Guest VM will have high CPU usage whenever high read/writes disk operations happen, making the Windows VM slow and unresponsive until the operations are completed. Boot time for the VM increased by a factor of 2 or 3. On MacOS Task Monitor, CPU load for the VM would be (100% * # Of CPUs allocated, like 400% or 600%) and Windows would go up to 100%. Same behaviour if the VM is stored on an external thunderbolt SSD drive or the internal SSD drive. I didn't notice other slowdown issues with MacOS but I didn't test extensively as I needed to VM to work. Prior to this MacOS update, everything was fine. I've restored a Time Machine backup to MacOS 10.14.3 and everything is back to normal with Parallels Desktop 14.1.3. Not sure if it's related to Parallels Desktop or MacOS but I guess it's always a good idea to wait a few days/weeks before upgrading MacOS, now I've learned my lesson... Anybody having a similar problem?
