Quickbook desktop 2021 only using 1 CPU core. Does the QB Desktop 2022 version uses multiple cores?

I have noticed Quickbooks Desktop 2021 uses only 1 core. That's why Quickbooks is very slow even on modern fast multi-core CPUs.

 

Does Quickbooks Desktop 2022 use multiple cores?

Great information!  I will say that I find QB 2022 quite a bit faster than 2021, probably because 2022 is a 64-bit app which runs natively under Windows.

How did you notice this?  How can I check 2022?

Hi BigRedConsulting,

see attached screenshot for reference, and see instructions below.

 

This is how you can check the number of CPU cores currently used:

 

1) Open Windows Task manager > go to the Performance tab (make sure the graph display each single core, if not right-click on the graph > Change graph to > Logical Processors

 

2) Close all other apps and browers to reduce CPU utilization to minimum.

 

3) Start a long and high processing Quickbooks Desktop task: for example Employees > Payroll Setup (this gives you time to observe CPU utilization.)

 

4) Observe the CPU performance graph. As you can see from my screenshot, my multi-core CPU only show 1 core utilized. That's why, even with the most powerful computer setup, Quickbooks Desktop 2021 is always going to be slow.

    Has there been any update on this for 2024?  We still suffer with poor performance even though it is on a very fast server (lots of cores may not help).  I am considering a new server and would try to optimize it for single thread if indeed that is still the case.

    Try changing your static IP address of the server in the drive map e.g \\192.168.1.30\quickbooks

    to become using FQDN or \\PCNAME\Quickbooks

    That has nothing to do with how many cores the server side application uses.
