If you have a multi-user version of QuickBooks, some situations cause QuickBooks to run slowly when two or more users are working in your company file.
For the best performance in multi-user mode, be sure to install QuickBooks or the QuickBooks Server on the same computer where the company file is located and set up that computer according to the recommended multi-user setup.
Where to store your company file
Whenever possible, place your company file on a computer that has QuickBooks installed. For more information, refer to the recommended multi-user setup.
Select a computer that meets or exceeds the recommendations for processor, memory, and disk space. The amount of RAM on the computer can significantly affect performance.
Select a computer with the least amount of non-QuickBooks activity.
Tips for day-to-day operations
You can do most day-to-day tasks in multi-user mode without noticing much difference in performance.
Tasks that take a long time to complete, such as running large reports, can affect performance for other users. A few tasks, like finding transactions, temporarily prevent other users from working on the company file. Consider doing these tasks when other users are not working in the company file. For the best performance when completing these tasks, use the computer where you store your company file. If that computer is not available to you, use the fastest computer connected to the network.
You can also improve the performance of day-to-day tasks by modifying your QuickBooks preferences.
In the Reminders preferences, select "Don't Remind Me" for tasks for which you don't need a reminder.
In the Reports & Graphs preferences, select "Prompt me to refresh" or "Don't refresh." Refreshing reports automatically can slow performance.
