Thanks for explaining your concern in such a great detail, @athomas57.

If you're having performance issues with your QuickBooks QuickBooks, it's most likely a company file issue. We can manage your data file to resolve this.

Beforehand, let's make sure the QuickBooks installations and the Database Server Manager on the host or server, are up to date. To update QuickBooks, check out Update QuickBooks Desktop to the latest release. To update the QuickBooks Database Server Manager, see Install, Update, and Set up the QuickBooks Database Server Manager.

If it still takes longer to open QuickBooks, there's a possibility that this issue is due to your company data file size. There are no actual limits on the size of your company data file, but performance may be hindered if your network is not capable of handling large data files. If you have a large file and performance is slower than what is needed, you can reduce the size of your company file.

Then, I suggest running the QuickBooks Diagnostic Tool. It helps fix common errors or issues with Microsoft components the QuickBooks program uses.

1. Close your QuickBooks.
2. Download the QuickBooks Tool Hub file.
3. Open the QuickBookstoolhub.exe file. It gets saved in the download folder.
4. Follow the on-screen steps to install and agree to the terms and conditions.
5. Click Finish.
6. Double-click the icon on your Windows desktop to open the tool hub.
7. In the QuickBooks Tool Hub, select Program Problems.
   
8. Select QuickBooks Program Diagnostic Tool. Let the tool run. It can take up to 20 minutes.
9. When the tool finishes, restart your computer and relaunch QuickBooks.

If the issue persists, you can follow the additional steps outlined in this article: Solutions for When QuickBooks Stops Working.
