Thanks for reply! Got it! To show all threads, type H in top in Linux. Then we see that java is multi-threaded, and uses all CPUs. But still, Tomcat and java seems to be the bottleneck in our system. I tried to make java use more memory, but with no luck. I tried with: in /usr/bin/dtomcat4: CATALINA_OPTS="-Xmx300M -Xms100M $CATALINA_OPTS $JPDA_OPTS" But this made no difference to the memory consumption or the performance. When starting Tomcat, it uses less than 100M. MySQL uses only a fraction of CPU compared with java, and there are several SQL queries in every page of the web publishing system. Is there any way to increase the preformance of Tomcat and java without tuning the application (=the Java Server Pages)?
