You may want to add the following JVM tuning parameters to the JAVA_OPTS in the bin/run.conf (UNIX) or run.bat (Windows) file:
-Dtomcat.util.buf.StringCache.byte.enabled=trueEnables the byte array to String conversion caching.
-Dtomcat.util.buf.StringCache.char.enabled=trueEnables the char array to String conversion caching.
-Dtomcat.util.buf.StringCache.trainThreshold=5The cache is built after a training period, during which statistics about converted Strings are kept. The value of this property specifies the number of String conversions to perform before building the cache.
-Dtomcat.util.buf.StringCache.cacheSize=2000The maximum number of String objects that will be cached, according to their usage statistics.
The effectiveness of the StringCache can be checked using the JMX-Console. Look for StringCache under Catalina in the JMX-Console page.
For the JVM command-line, the following settings can be used:
Memory set at just over 1G for each server
MaxPermSize adjusted to 256m
