A detailed analysis of the jqs.exe process
A look in the Task Manager of Windows XP or Windows Vista will reveal all the applications, open windows and processes that are running on the computer system. Many of the processes displayed are important system processes that are required to run Windows properly.
A process that is appearing quite often is jqs.exe. It is the Java Quick Starter which gets installed alongside the Java Runtime Environment on Windows XP and Windows 2000. Its purposes is to speed up the launch of Java applets on the computer system.
This is done by loading necessary files used by the Java Runtime Environment that would otherwise be loaded upon file execution. This does mean that those files will reside in computer memory all the time being regularly preloaded into memory.
This results in a more cohesive and free flowing experience when one is browsing websites that have Java code or applets.
If you look at the system resources consumed by the jqs.exe process you notice that is it using between 1-2 Megabytes of computer memory and virtual memory most of the time which can sometimes raise to about 20 Megabytes. The amount should not be significant on modern computer systems but could still be seen as a waste of space.
Jqs.exe will automatically check system resources before prefetching information. If the system is in a high load situation the process of prefetching data will be stopped until the situation clears up.
Many users have reported high input and output processes by the jqs.exe running on their computer system. The load and memory usage is somewhat regulated by Windows which will regularly clean the cache to reduce system load and memory usage. The process should not make to much problems on modern computer systems with lots of computer memory and processing power though.
Users with older hardware and those that do not make use of Java regularly (or at all) should consider deactivating the process to save memory and processing power. This can be done by opening the Control Panel in Windows, double-clicking the Java icon and selecting the advanced options when the panel opens.
Locate the miscellaneous entry in the menu and uncheck the Java Quick Start box to disable the jqs.exe process from being launched. The box is active on Windows XP and Windows 2000 systems by default. Unchecking it will have the result that the jqs.exe process will not be loaded during system startup. It might have the result that Java applications will have a higher startup time.
Jqs.exe is not activated on Windows Vista as the system uses its own pre-loading system.
