Poor Windows 10 Performance of Parallels Desktop 15 on macOS Catalina

Just a quick note for macOS users.

I just installed (and removed) Parallels Desktop 15 Edition on my MacPro (2013) with 64GB memory and 12-cores, which is running the latest version of macOS Catalina as of this post. The reason for this install was to test some RIGOL test gear software which only runs on Windows.

The basic Parallels installation went fine and so I also installed Windows 10. Everything went well. I then installed all the prerequisites for the RIGOL software, including NI-VISA for Windows and the drivers, etc.
had read a number of reviews comparing Parallels to BootCamp (and other approaches); and the bottom line seemed to be "the performance is so slow you are better off to buy a cheap Windows PC." .

But I thought to myself, since I have 64GB of RAM and 12-cores (and am quite happy about the performance of this MacPro, 2013), maybe I'll have a different outcome.

Alas, I experienced the same very slow performance others talked about in reviews. I tried adjusting various Parallels configuration switches and sliders in the control panels, rebooting a number of times, but I ended up just deleting Parallels off my Mac.

If I *really* must have Windows for some test equipment applications, I may just go the "buy a cheap PC route", which is the same advice from many reviewers and commenters out there in "discuss and share" land.

Cheers.

NAME
gnome-desktop-item-edit - GNOME Desktop file editor SYNOPSIS
gnome-desktop-item-edit [--create-new] filename DESCRIPTION
gnome-desktop-item-edit is the GNOME Desktop file editor, which you can use to create or edit the .desktop (known as desktop) file. GNOME uses a standard desktop file specification as proposed by freedesktop.org. A desktop file consists of a number of name-value pairs that define how a desktop should organize a particular application. As this is defined as an open standard, integration of applications into GNOME Desktop is relatively straightforward. A basic entry in the desktop file must start with a tag called [Desktop Entry]. It can then have a number of name-value pairs as defined by the standard. The minimum entries are as follows: Name the name of the application Comment a textual description of the application which is displayed as a tooltip message by gnome-panel. When set appropri- ately, the comment can be localized within the same file. Exec the name of the actual executable Icon the file name of the icon image Type the desktop file type Categories a multi-string field which is used by gnome-panel to group applications into the appropriate categories. These desktop files provide the information to gnome-panel, which places the application in the appropriate locations on the panel. In a similar manner, the GNOME file manager (Nautilus) uses information from the desktop files to display the 'applications:///' view. OPTIONS
The following options are supported: --create-new Creates a new .desktop file. OPERANDS
The following operands are supported: filename The name of the desktop file to be edited or viewed. EXAMPLES
Example 1: Editing an existing .desktop file example% gnome-desktop-item-edit fullpath/filename This command invokes the launcher dialog and loads the contents of the specified desktop file into the relevant fields. EXIT STATUS
The following exit values are returned: 0 Application exited successfully >0 Application exited with failure FILES
The following files are used by this application: /usr/bin/gnome-desktop-item-edit Executable for GNOME Desktop file editor /usr/share/applications/ Location of system desktop files ATTRIBUTES
