    I've been experiencing the same slow down/performance issues with my Windows 10 after upgrading to Parallels 14 - (multiple apps affected!!). Several times over the past 2 weeks, I have had to either reboot or abandon the use of the Parallels VM altogether. VM freezes, spinning ball. Definitely a step down from Parallels 13 in terms of functionality. This is frustrating I too am considering whether or not Parallels is worth the cost $$$ (esp. now with the annual renewal). I understand that there are always certain bugs to be worked out in a beta/pre-release. But I feel that I already want a $$$ refund - wish I had not enthusiastically embraced the 14 upgrades. Hope this is remedied soon!!

    Loyal Parallels User. (Thankful for the good that Parallels Team has done!)

    That one was created when the issue was occuring, the VM being stopped was because the VM had grinded to a literal halt. It takes time for it to begin working again afterwards, that's why I also pulled up the W10 Task Manager onto the screen so the CPU and Memory usage was visible if it didn't read in the report. I've created another during another spike under 274344127.

    The spikes are multiple times per day, sometimes when multiple programs are open, sometimes when nothing has been opened and it's only just logged in.

    I can confirm that the reports I've sent for are for the VM with the issue, the other VM is a separate environment and may or may not have the issue also, not too interested to find out really as this is the one I want working.

    This issue had never occurred prior to the v14 update. Since then it's a daily hindrance, I can sometimes reboot to improve the speed but even that isn't certain.

    Given the release of Mojave is between 1 to 4 weeks away, would be great to not have to guess what combination of MacOS, Windows and Parallels is going to give me the ability to work an entire day without crashing, otherwise until it's fixed I'm going to have to run a different VM.

    Downgraded to 13, all problems disappeared.

    I've found that the system seems to work fine after initial boot. However after an interval, it seems to stop responding to things. Gets slower and slower to actually do anything. Just clicked on a drive to get a directory listing, and a minute has passed without displaying this. Usually end up having to restart the virtual machine, but sometimes this won't work and it just stops. No pattern to when it happens except perhaps longer use. Does seem to be a real pain. :(

    Soooo, any Parallels support person want to let us know that this is a known issue yet?

    I've just used the Parallels toolbox option to disable sleep on the computer, and it has worked perfectly for the whole day. Now I have sleep in the Mac settings, set to only switch off the screen, and nothing else, yet if I don't use the computer for a while the problems start to appear....

    I reported in another thread but never saw a response, I am on a MacBook Pro 2018, Parallels 14, and I have times where there is non response from mouse/keyboard, and the symptom is System is using the disk pegged at 100%. It goes away in about 5-10 seconds depending on the instance.

    I haven't even read this thread yet but I am running into the same problem. Performance is horrible and I have a maxed out 32 gig 6 core 2018 machine. the vm is basically unusable and continues to crash. I've uninstalled the tools and reinstalled and still a problem. I even ran their interrupt tool and it didn't show anything out of the ordinary. This is a reoccurring theme the last couple of years, I really wish they would focus on keeping things performant.

    I downgraded to Parallels 13 too, and so far so good for me. I hope they can fix this, I don't want to be on ver. 13 forever. But the performance lags were extremely annoying.

    The downgrade fixed a symptom. With 14 the chrome gpu process with a single web page open was taking 300-600 megs of memory. With 13, opening the same web page, chrome's gpu process only take 16 megs which is back to normal. The machine is better but still overall sluggish. Basically performance is pathetic and in reality it has been like this for 2 years. They say their drivers can run the vm at 5k resolutions but it can't. Only when the vm is booted on the laptop screen with a lower resolution does the vm remotely usable. Kind of sad, because light weight performance hypervisors have been solved for quite a while

    Yes, it behaves as if 'something' is happening, but no clue really as to 'what'. Just sits with things responding really slowly. I've had task manager apparently hang, and refuse to close, and when in this state, the system won't even shutdown. It accepts the shutdown command, and then just sits. A real pain, since V14, fixes an issue I had with a particular software package, which makes me want to keep it.
    I had interesting behaviour yesterday. I used Parallels toolbox, to set the system to 'Do not sleep'. With this selected, I went all day without an issue. Now my system was set to only sleep the video, and Windows itself set to not sleep, yet turning this off seems to have affected the problem, though I was seeing issues, when the system should not have gone to sleep at all. Possibly helps to show what is actually going wrong....

    I played around with the VM config a bit, and it's weird but I don't have any problems (on 14) when using 4GB of memory for the VM (physically I have 16GB total in my MBP). Problems come back when increasing e.g. to 8GB. Really strange ...

    @parallels we need an update. You've had enough reports to know that it's a problem and we need you to address this.

    I believe/hope that I've finally solved it, at least for my Windows 10 VM. After months of ever growing frustration, various reinstalls of W10, downgrades to Parallels 13 and a tremendous loss of productivity I today unchecked the 'expanding disk' setting (see configuration --> hardware --> hard disk --> advanced settings --> properties). And since having done so Parallels 14 runs smoothly again, no lags, I can hardly believe it. Other optimisations/settings that I (still) have implemented, but that individually did not solve the lags were: disabling superfetch and windows search, mirror displays (OSX setting as I use an external display). Unchecking the 'expanding disk setting' will cost some disk space (about 35GB in my case), but that's just a minor inconvenience when compared to having a non-functioning lagging system. Hope this works for others as well.

    These "fixes" (standby delay, expanding disk) are not fixes, but workarounds - their greatest value is hopefully pointing @parallels to the true problem(s) with lag and disk so this can be fixed for everyone for once and for all.

    It is not Mode 0. It is setting the standbydelay to 0. This actually prevents the machine entering hibernation. Mode 0, just means 'normal hibernate', which hibernates into RAM. It does still hibernate though...

    As the later poster says, this is just a 'bodge round', but it does seem to work!...

    Yea i see. Though it doesn't make any sense why that value would have any affect and I'm not changing that value just for parallels.
