    Unusable performance on a €5000 machine, and these dipshits still think I am going to pay €80 for another year of their crap app? Haaa, ha, ha. That was my reaction to their reminder email today.

    On top of slow Excel and Outlook on the Windows 10 VM, accessing the Mac SSD drive takes 20-30 seconds to establish the access. After that the access to the drive is fast, but if I switch to the Mac for a few minutes and switch back, it takes again the same 20-30 secs to access. I think the Outlook performance are related to the case that the mail box files are all on the Mac drive (to be backed up with my Mac. All this is new on PDT 15.

    I can live with the slow Excel (not using it much and if I need, I can use it on the Mac as well), but the slow access to the SSD drive makes it impossible to use. Any ideas ?

    Hi and could you also please reproduce the issue and collect the tech data report and then post the report's ID here?

    PERSONAL EXPERIENCE: (Extremely frustrated like everyone else) I've been following this chain for months after experiencing severe degradation of performance with v15. Reverted to v14, with modest improvement, but still VERY SLOW as of today. I've delayed upgrading MacOS to Catalina pending resolution of the Parallels problems.
    REQUEST: Will Someone from the PARALLELS TEAM please tell us something useful (or at least hopeful)?
    URGENCY: We needed a fix months ago. Without a fix, there will be an escalating number of users migrating to alternative workflows without Parallels.

    Maria,
    could you give US some sense of what Parallels is ACTIVELY doing to address this issue? I ask because of the recent experience with the mouse freezing issue, amongst others. Through MANY build updates over two major version updates, we where asked many times to provide these technical reports. And yet, over more than a year a fix never materialized, and when it finally did, Parallels didn't even list it as a fix. it just quietly happened, almost as if it was just a side effect of something else, and Parallels actually cared so little about the mouse problem that it never made it into the bug tracking system, and all the "send us a technical report" was so much "Make these retard customers feel better, but keep ripping them off" lying. Sorry to be so blatant, but yes, as far as I can tell, Parallels was lying to customers then, and lying to customers now. Which is why I am hoping you can help prove me wrong, by showing us this issue in the bug tracking system, and letting us know how many engineering hours are currently being assigned to it, and what priority management has given it. Given the rather shabby way Parallels has treated its customers and these kinds of issues historically, I think Parallels owes us that. Many of us have been customers for many years. And we are tired of being lied to and treated like trash.

    macbook pro 16 (64gb, i9 2.4) Catalina 10.15.2, PD 15.1.2 (47123) Pro Edition. The performance was not nice using Parallels hypervisor (Windows 10 Pro 1909), the UI was bit frozen (delay to open start menu and etc..) when I was opening project in VS 2019 or building it (.net core project). The project is very small (few classes and controllers). Seems disk I/0 caused high cpu usage ???. I switched to Apple hypervisor in settings for now and it is much better

    How dare you treat your customers like this. What a completely frustrating and totally dissapointing result. 3 days of wasted work - only to find v15 is almost beta level software at best. The support was even worse, 4 hours of useless attempts to get things operating made it worse, so I pulled the plug. After years of buying this VM, we won't be EVER renewing any license from his mob. Now I have to port all the applications and data to a new PC. Wish me luck - nothing better to do for the next 2 days. Appalling that anyone would actually charge money for this. As a software developer - Mid range, I find this type of developed application a farce. I'm sure if someone made a tool to port this to Bootcamp they'd make a fortune.

    I have the same performance problems which I can't continue like this (2 days ago, I was at a customer site and had to wait few minutes while the customer is looking at my screen on the projector, waiting for my Outlook to open, accessing files from the Mac and opening Excel, huge embarrassment ... :-( ).
    How do you downgrade ? I just tried it and my Windows 10 PVM does not start after the downgrade. Do I need to do something before I downgrade (the instructions was to shutdown the Windows 10, take a backup (just in case), install version 14 (which will auto remove version 15 - it did) and start). I have try reboot also, just in case something was needed reset, but does not work, the PVM does not start.
    Thanks for any help.

    Hi All
    I don't know if this will help anyone but for what it's worth here we go.

    I have had the slow windows 10 issue for a very long time now but today have come across something that has made a significant difference!

    There is a process in the activity monitor called "photoanalysisd." It is the process by which apple categories the picture files in photos and help with facial recognition and search features. This is ALWAYS churning away when photos is not open. To cut a long story short this eats up your CPU if you have a lot of photos that need to be categorized and reeks absolute havoc while trying to use the virtual machine. If you do a google search of "photoanalysisd" there is a whole lot of chatter about it being a beast that can never be stopped literally).
    Anyway I found this work around in an article as follows:

    QUOTE (SOURCE:https://dev.to/gjbianco/controlling-photoanalysisd-3j2a)
    "Shut down Photos. 
Hold down option key while tapping on Photos in the Dock -> This brings up the option of choosing a library, or creating a new one!
Create a new library, call it "Empty Photos Library"
    Done. Keep the original library around and switch back to it using the same system in case you need it.
    I even tried deleting the Photos app - turns out that is impossible. Photos is basically the Adobe Acrobat of 2019. A horrible POS that installs itself like a Kraken into your system, impossible to remove.
    Nothing else worked for me in OS X Catalina."

    This was the only way to stop photoanalysisd from eating up a ridiculous amount of my CPU and once I have done that windows 10 is the MOST responsive I have ever had.

    Worth a try. The only down side is that you have to "option click" the photos tab and select your correct photos library any time you want to open your photos library afterwards but a small price to pay for a much faster machine!!
    Kind regards
    Mark Botham-Clarke.
