I suspect there is a problem with my > application (I´m not asking about this, that´s my problem :-( ) Tomcat... yeah, I was just working with tomcat for the first time at my recent contract, and not overwhelmed by it (loathe the many-hundred-line java stack traces, as opposed to clear error messages). A couple things to try: first, as a quick fix, renice the process down by a couple of points. Sometimes, giving other processes *some* time slice will speed things up. Second, check the JAVA_OPTS for tomcat. I was working with confluence (a wiki), and had to seriously up the heap max and the perm max (-Xmx and -XXm, I think the parms are). The former defaults to something like 128m and the latter to 64m, and I had to take that up to either 768m or 1024m for the first, and 256m for the second. When I did that, CPU usage went down a bit. mark -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
