The information in this article applies to:

  • Microsoft Internet Explorer version 3.0, 4.0 for Windows 95

SUMMARY

Microsoft Internet Explorer includes a Just-In-Time (JIT) compiler that changes the manner in which Java programs are run.

MORE INFORMATION

The JIT compiler translates bytecodes into native machine code. This compilation process is done only once, and a link is created between the bytecode and the corresponding compiled code. The purpose of this process is to increase the speed at which Java programs run. You may realize a speed increase of more than 50 times when some mathematically intensive functions are performed.

NOTE: Some Java programs may run at the same speed or slower when you are using the JIT compiler.

You can enable or disable the JIT compiler by using the following steps:

  1. Click Start, point to Settings, and then click Control Panel.

  2. Double-click Internet.

  3. Click the Advanced tab.

  4. Click the Enable Java JIT Compiler check box to select it or to clear it, and then click OK.

NOTE: You must shut down and restart Internet Explorer for the change to take effect.
