Last night, we switched the customer box in question from running Tomcat under Java 7 (64-bit) to Java 8 (64-bit), and all day today, the processor load from the Tomcat server has been dramatically lighter. I haven't seen the overall CPU over around 70% today, and haven't seen the Tomcat's JVM job usage over 30% (as I type this, the overall is at 48.1%, of which the JVM job is a mere 7.8%), where before, it was peaking at full saturation, with the Tomcat JVM job alone accounting for as much as 90% or more. I am cautious about this, but I think maybe just the switch to Java 8 alone has solved the problem. -- JHHL -- This is the Java Programming on and around the IBM i (JAVA400-L) mailing list To post a message email: [email protected] To subscribe, unsubscribe, or change list options, visit: https://lists.midrange.com/mailman/listinfo/java400-l or email: JAVA400-L-request-+hD5IHI5Xscn3HwCXmMcX9BPR1lH4CV8@public.gmane.org Before posting, please take a moment to review the archives at https://archive.midrange.com/java400-l.
