Your computer will automatically generate a disk queue length when you switch on your computer. In general, the disk queue length of a computer can affect its performance, because this is basically the list of tasks that your computer has to accomplish. In this article we will tell you what exactly is an average disk queue length and what it does to your computer.

An average disk queue length tracks the number of requests or activities you do during an interval. Let’s say you want to open a program, following by an Internet browser, and then go on Skype to chat with your families. Your computer will put all these tasks in a queue, and the performance of your computer will depend solely on how your computer handles them. For a single disk system, the moment you run two requests simultaneously, your computer might lag or slow down when processing the requests. This is the time when your computer is telling you he can only handle one request at a time.

When your computer indicates a high average disk queue length, it means you have gone past what your computer can handle. A simple way of getting things back to normal is to cancel some non-critical and unnecessary programs and try doing them after you have finish one task. Most of the time, closing some programs, and cancelling some requests can speed up your computer and get it back to its normal speed.

Before using your computer, you should put into consideration how and what you are going to use it for. Make sure you know the specs of the computer by looking for it in your Control Panel. Older models tend to be inflexible with disk queue length and slow down faster when there are more than two tasks done at the same time. These computers are not built for multitasking purpose and are basically used for typing and other simple computer tasks only.

So what are the other alternatives you can use to prevent and fix a high average queue length? It’s easy, you just have to reconfigure your computer. If you find that your computer is having a hard time catching up then add more RAM to it. Computers with higher RAM tend to work flawlessly for people who prefer multitasking. You can also add more disks to your computer.

Another trick is to simply monitor your queue and be a little cautious when working. Look out for those programs that use up a lot of memory and avoid using those programs if they are not necessary.

To sum it up, the performance of a computer depends on the disk queue length. To avoid lagging or hanging, one should always close the programs they are not using, and if you have a deep pocket, add in extra arsenals such as RAMs or disks.
