How do I improve performance when running webMathematica on Solaris?

When running webMathematica on Solaris, you should note that improved performance can be obtained by using a “one-to-one” model for Java threads. An alternative model, “many-to-many”, can lead to lower performance due to thread starvation.

Under J2SE Version 1.3, “one-to-one” is the default thread model for Solaris 9. However, for Solaris 8, the default is “many-to-many”. A thread model of “one-to-one” can be obtained on Solaris 8 with the JRE option -Xboundthreads. For Apache Tomcat, this can be set with the TOMCAT_OPTS environment parameter.
