Resolve QuickBooks Desktop performance issues: Manage your computers

Optimise your server and workstations to minimise performance issues in QuickBooks Desktop.

Enhance your computers

QuickBooks system requirements will support most QuickBooks users. If your computer system meets these specs and still experience performance issues, you may want to increase your available RAM. Remember your goal is to increase the amount of RAM available to QuickBooks.

To know the amount of RAM you need for QuickBooks, 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 experience performance issues, you may want to upgrade your server to 3 GB of RAM.

Virtual Memory

1. Increase a computer's Virtual Memory (VM) to 2 GB plus 2 GB for each major application you run on the computer.
2. Be sure VM is runs on an internal hard drive.
3. If your server has multiple internal drives, store the data file on one drive and the VM on another drive.

Competing Programs

A competing program is one that runs at the same time as QuickBooks. Each program requires RAM and processor capacity. You can see your programs in the Task Manager. Check out the Processes Tab.

1. Shutdown programs and processes not in use on your computer. This enables the operating system to assign more RAM to QuickBooks.
2. If you can't shut down a program, move either QuickBooks or the other program to another computer. A common example is the Exchange program that runs your e-mail system.
3. In some systems, there are too many programs that run on the Domain Server for QuickBooks to run efficiently. You might want to move QuickBooks to another server.

RAM Improvements

1. Add memory chips. If your server has four sockets, and 2 sockets have 1 GB DRAM chips, install two 1 GB DRAM chips in the empty sockets.
2. Upgrade your memory chips, e.g., replace 1 GB DRAM chips with 2 GB DRAM chips.
3. Increase workstation RAM.
4. Be aware of your operating system's limits on the amount of RAM it supports.

Upgrade your operating system

If you upgrade the RAM on your workstations and server and it doesn't resolve the issue, you might want to upgrade your operating system. Older operating systems have lower limits on the amount of RAM they can support.

Upgrade Computers

If you decide to upgrade your server and/or workstations, please consider the following:

1. Make sure that the computer that will store the file is a true server ( not a service like Dropbox ).
2. Fill all of the RAM slots with the highest capacity chips.
3. A 64-bit computer & operating system.
4. A fast clock speed of 2.2 GHz or more.
5. A fast hard drive rotational speed, e.g., 7,500 or 10,000 rpm, or a solid state drive.
6. A fast Network Interface. A 1 Gigabit per second (Gbps) card on your server can increase bandwidth.

Terminal Server

If you run QuickBooks in a terminal server environment, you can estimate the amount of RAM on the server in two ways. The first is you need 0.5 GB of addressable RAM for each user. If you have five users, you need 2.5 GB of RAM. The second way is:

• For 5 users, you need 2-3 GB addressable RAM
• For 10 users, you need 3-4 GB addressable RAM
• For 15 users, you need 4-6 GB addressable RAM
• For 20 users, you need 6-8 GB addressable RAM

Note: Intuit supports Terminal Services mode only for QuickBooks Enterprise.

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.

Use a computer on a network

1. Store your company data file on an internal hard drive on a computer on your network.
2. Use an external hard drives or a flash drive only to back up your data file.
3. We don't recommend a Network Attached Storage (NAS) drive. We design QuickBooks for Windows to store files on a computer with a Windows Operating System, or with a Windows compatible SAMBA share (Enterprise only).
4. QuickBooks works with a server running a RAID (Redundant Array of Inexpensive Disks). We don't recommend them because they've been known to cause performance issues.

Non-Dedicated Server/Host

If you don't have a dedicated host or server, use this info to help decide which workstation to use to save your file. Save your data file on the workstation that:

1. Has the full QuickBooks program on it.
2. Store on the computer you use most. This will minimise data transfer over the network.
3. Has the most RAM.
4. Has the fastest clock speed.
5. Has the least non-QuickBooks activity.

Your Data Folder

When you create or move files, QuickBooks uses these default locations:

Windows 7, 8, 10: C:\Users\Public\Public Documents\Intuit\QuickBooks\Company Files

Optimise 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 happens when one NIC is set to a specific link speed and duplex and connects 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, reset all of your NIC's Link Speed and Duplex to an automatic setting.

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