Re: JVM job for Tomcat taking lots and lots of CPU

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.
