You might see performance improvements by using a Just-In-Time compiler with your servlet runner. To take advantage of the TYA JIT that is installed on each Servlets.Net server, you will need to run this command prior to starting your JRun Service Manager:

export JAVA_COMPILER=tya

If you want to always use the JIT, we suggest adding a JAVA_COMPILER=tya line to your .bash_profile file and adding JAVA_COMPILER to the end of the export line in that same file.

If you are using JDK1.2, the built-in JIT is automatically used. It can be disabled with a JAVA_COMPILER=NONE environment variable.
