If you have poked around your computer’s task manager listed of processes, then you have likely come across the Jqs.exe program that is running. JQS.exe is not computer malware. It is a computer process called the Java Quick Starter helper application that is designed to help Java applets and web applications to run and load faster by pre-loading or fetching Java Runtime Environment files to load into memory. Depending on the version of Java and Operating System you have, the JQS.exe process will use roughly 1.5 megs of regular computer memory and up to 2 mb’s of virtual memory.
How Can the Java Quick Starter (JQS.exe) Help Your Computer’s Performance?
The JQS process will make the initial startup or load time for Java Applets and applications happen faster. It was incorporated into the Java SE 6 update 10 version of Java and was included in subsequent releases. JQS.exe is enabled by Java on Windows machines running Windows XP and Windows 2000. It is not turned on by default on Windows Vista since Vista embeds separate pre-loading functionality. JQS quits running if you are using a laptop that is on battery power on its own and restarts itself once your power cable is plugged in. It helps achieve an improvement in overall Java performance by pre-fetching commonly used Java class files that are used in we applications with a limit of 20 MB of total RAM usage. When JQS is enabled, Java performance is significantly improved. If you like to keep more of your RAM free or just don’t use web pages that run Java much, you will see a slight performance improvement by disabling JQS.exe.
