This article is Part 2 in a set of 3 articles regarding performance issues in QuickBooks. If the steps in this article do not resolve your issues, try the steps in the other articles:


Enhance your computers

QuickBooks system requirements will support most QuickBooks users. If your computer system meets these specifications and still experience performance issues, increasing your available RAM may improve the condition. Remember that your goal is to increase the amount of RAM available to QuickBooks.

To know the amount of RAM needed for QuickBooks operations, multiply the size of your file in GB, by the number of users in the network. So, if your file size is 500 MB (0.5 GB) and you have 6 users, then you need 3 GB of RAM in your server. If you have only 2 GB and you are experiencing performance issues then consider upgrading your server to 3 GB of RAM..

Where to store your data file

  • Where you store your company data file can have a noticeable effect on the performance of QuickBooks.
  • You can set up a folder in your C: root directory to store your data file and ancillary files: C:\QBData\filename.qbw.
  • Remember to move the entire data folder when you need to move the data file.

Optimize your network interface card (NIC) settings

View and Edit your NIC settings

Network interface card (NIC) settings can slow the transfer rate if you have duplex mismatches. A duplex mismatch occurs when one NIC is set to a specific link speed and duplex and is connected to a NIC set to a different value. A mismatch can reduce your bandwidth to a few Megabits per second (Mb/s). To avoid this issue, reset all of your NIC's Link Speed and Duplex to an automatic setting.

  1. Click the Microsoft Windows Start button, select Control Panel. (In older Windows versions, you need to select Settings before selecting Control Panel.)
  2. Double-click System and select the Hardware tab.
  3. Click Device Manager.
  4. Click the + next to Network adapters to expand the list.
  5. Right-click the NIC and select Properties.
  6. Click the Advanced tab.
  7. Under Property, select the Link Speed & Duplex option (the option may be called something else similar).
  8. Click the Value drop-down arrow and select Auto (the option on your NIC could be named something else).
  9. Click OK and close the window.
