QuickBooks has been releasing QuickBooks Desktop with the same Cache parameters for forever, even though each user likely has substantially more processing power than they've had before. I've had to increase our cache parameters on each iteration of QuickBooks (we have tons of internal QuickBooks files for clients). I was just running these rule changes in QB's 2022 and found it incredibly slow and it dawned on me that I never increased the cache when I added QB's 2022 to the server. Increased base and max to 8GB and minimum to 4GB, and VOILA, runs smoothly again. 

If you're running a QBDBM on the server, you'll need to do the registry edit on the server and restart the service. If you're using it locally, you'll need to do the QBW.ini modification I believe.
