Parallels 13 macOS Sierra High Windows 10 slow performance

Hello community,
i have the newest version of parallels desktop 13 and since I have upgraded to macOS Sierra High my VM has really bad performance. Apart from many graphic bugs, when the VM is in fullscreen, it takes much longer to boot windows 10 and also when its ready, its slow. Parallels drop my battery fast as hell, I mean when my MacBook Pro late 2016 has 100% battery it drops like 70% in 3 Hours. Also my MacBook Pro gets hot when im on the VM, independent from what I am doing. What can I do to get a better performance without let my macbook running hot.

Thanks in advance!

I did now and I will inform if that really helps. Another problem I noticed is that when I start the VM with Windows 10, I always get a folder, which I deleted months ago in my waste basket on MacOs. I think I copied that folder from Windows 10 to MacOs and deleted it on MacOs. Now it always comes back in my waste basket on MacOs when I start the VM. How can I fix that?

@PatrickG5 was reporting a slow performance problem after upgrading to macOS Sierra High.
I'm having the same problem, I've been using Parallels for many years now and I really notice there's something with the performance after this upgrade (or is the Windows10 new version).

In any case, your suggested article is super generic article and not referring specifically to your latest version (13) of OSX latest version (I could have guessed my self that upgrading the Mac Book Pro Ram would make it run faster...)

Is there a more specific solution ?
 
i have to agree with Ranc i have a fusion drive on a 2016 iMac with 24gb internal memory . The time taken in starting windows 10 and running programs is ridiculous please give none generic help
 
Guys, could you please open Windows Task Manager in a time when you experiencing slow response and take a look what a process eats CPU?
 
nothing untoward on start up but takes an age to fire up also programs now take longer to load very frustrating . Also i use sage i have noticed since update in systems i have to now manually fire up sage data service even though it is set to start automatically . VERY FRUSTRATED
 
I have Parallels 13 Home Edition and since I have upgraded to macOS Sierra High my VM cannot perform basic tasks that I graciously used to do prior to the update.
  • It takes much longer to boot windows 10 and also when its ready, you still have to wait a few seconds for items on the Windows 10 Task Bar to be available.
  • I usually sync files between 2 external HDDs. Once the sync process starts, it slows down after a couple minutes to the extent of freezing while syncing files as big as 2.6 GB in my case, thus making the Windows 10 VM unstable. I have not only to force quit the windows 10 VM but also to restart my MacBook Pro to bring everything back to normal. Also there are many graphic bugs, especially when resizing the VM window. Trust me, it's very bad, did I say very bad. I spent 4 hours trying to troubleshoot the problem until I found this forum where people are sort of complaining about the same issue. As recommend earlier by "alexg", I opened Task Manager when the issue occurred and the CPU utilization was at 34% (it went up then went down, surely because the system froze). By the way I have the last Parallels 13 update "Version 13.2.0 (43213)".
  • I really think that you should probably review the boot performance of Parallels 13 with the new macOS Sierra High file system (APFS) "Apple File System" and how Parallels 13 handles large files transfer in this new environment (This is just a suggestion).
It will be great not only to acknowledge the problem and but also to let people know if potential fixes/improvements are coming up. It will calm down the community's frustration.
Thanks in advance.
Here is my MacBook Pro specs if it may help:

Model Identifier: MacBookPro12,1

Thanks for the link @alexg. This is quite a detailed article. To respond to your question, the 34% CPU usage was associated with several processes but the main one was my syncing tool (BestSyncc 2018). There was a spike for a couple seconds then everything went down to 3-5% because files transfer stalled. I tried to do it manually and I got the same result.
 
Yesterday I purchased and installed Parallels 13 on my 2017 iMac running Windows 10. Immediately, I noticed that booting Windows 10 now takes forever. Opening Windows applications result in a long delay much longer than with Parallels 12 which I replaced. Also the frames around the windows that I had customized to a specific color scheme have now gone to no color when they fnially do open. There appears based on these other posts, a recurring problem with Parallels 13. I just wanted to add my comments to the group to verify the same results. I hope a fix can be found soon as I now regret installing Parallels 13.
 
This is one of the windows that used to be (with Parallels 12) turquoise green on the top of the frame. Also the minimize, full screen, close buttons in the inner window have all become scrunched together. This is accompanied be extremely slow response time for opening this window relative to Parallels 12. I don't believe the VM settings are not maximized in that I have a 2017 iMac with 16 Gb memory and a 3 Terabyte fusion drive and it was working perfectly fine before I upgraded from Parallels 12 to Parallels 13.
 
Hi

I have been experiencing problems ever since I bought Parallels 12 on 17th August this year. I then received a free upgrade to Parallels 13 on 22 August, hoping that there would be better performance, but unfortunately, that has not been the case. I then paid for the Parallels Toolbox on 10th October.

I am running a Virtual Machine on the new Mac 4k retina that came out this year;
Windows 8.1 Pro 64-bit
Intel Core i5-7400 CPU @ 3.00 GHz, 1.0GB RAM, Parallels Desktop Display Adapter (WDDM)

Windows is running ridiculously slow, and my Task Manager states that I am constantly running at 100% disk space. I have partitioned to 4GB on Windows 8.1, which is exactly same as I have on my HP All-In-One, where I don't have any of these problems.

Please see attached image of Task Manager approximately 20 seconds after I opened Windows;

Outlook, Word, Excel and Chrome are endlessly "Not Responding" (even my Task Manager!) and my Mac starts crackling like it's about to explode.

I had McAfee Total Security on both Mac and Windows. I stripped it off Windows as in one of the forum threads it said it would speed up my computer and I installed Kaspersky, but absolutely nothing has changed.

Please tell what information you need to fix this.

Please bear in mind this took me 20 minutes to copy and paste the command prompt text into Word, I am absolutely livid.

I would be happy to send you privately the screen recording I made using your toolbox for 4 minutes and 22 seconds of it.

Hi @StanN, please shut down the virtual machine and go to it's VM configuration settings, Hardware -> USB & Bluetooth ->Advanced settings -> untick " Enable USB 3.0" and check out the virtual machine performance.
