After the recent updates Windows guest OS became very sluggish. Sometimes I click Windows explorer and the explorer window will freeze for a few seconds. This is extremely annoying. I paid for the latest Parallels update, but it works very slow. Over the year Parallels is becoming less and less reliable. When I started using it in 2016, it worked almost like a native Windows, but now it freezes here and there.

Windows is very sluggish

I decided to run my Parallels VM in a HFS+ filesystem because of this, precisely.Just a note to my previous post. The 3 steps breaks the link between the old backups and the latest version of the VM. APFS no longer has to keep track of the file differences, so Parallels then runs fast.
I had the same issue. At some point after I updated to v15 (or perhaps after updating host Mac OS, can't say for sure), Windows guest machine started to behave "sluggish": from time to time any operation could take quite a long time, then there would be a period of everything working fine, and then sluggish again. At the same time, Linux guest machine was working absolutely fine.
I tried allocating only one processor, I tried switching to Apple hypervisor - nothing helped. But then I saw a recommendation here in the thread to add Parallels machines folder to exclusions of Spotlight (Privacy tab), and after that the issue was gone! So I am a happy camper now, big thanks to those who shared this recommendation.

I've just tried this and it worked a treat, a big thank you for the tip.Hello,
I have this problem too and I tried several things. At the moment my Windows VM runs smooth and I hope it will stay so. I disabled the Spotlight search for the directory where the VM (.pvm) ist stored. Maybe PD writes in the .pvm file (which is about 150 GB) every time when you open a window or type something and Spotlight will index the .pvm file because the file has changed. In my setup the hdd of the VM ist self-inflating, maybe this could also be a reason.
Please try this advice and give response here in the forum if it works or not.
Johann
