Java Quick Starter (JQS) improves initial startup time for most Java applets and applications. This feature was added to Java in release Java SE 6 update 10 (6u10) and will be available in all future releases.

JQS is enabled by default in Windows XP and Windows 2000 operating systems and is not necessary on Windows Vista as Vista offers its own pre-loading mechanisms. A process called jqs.exe will run in the background in order to allow quick statup. jqs.exe will be loaded after a Windows restart. Instructions on how to disable the JQS and the jqs.exe process are below.

The startup performance improvement is achieved by periodically pre-fetching some of the most heavily used Java files into memory (occupying no more than 20Mb of RAM). Later, when Java is launched, much less disk I/O is required which makes startup much snappier and noticeably faster.

Note: JQS service will perform runtime checks and stop running when a laptop is running on batteries. JQS service will resume when the power cord is plugged in, as performance benefit of JQS is largely dependent on overall system configuration.

不要通过 管理工具->服务 来启用/停用 JQS 服务。
应该通过 控制面板->Java->高级->杂项 来启用/停用 JQS 服务。
