----------------------------------
Summary: The JVM option -XX:+TieredCompilation is being set for HotSpot
JVM's in standalone.sh, but this slows throughput in all tested workloads
Key: AS7-4547
URL:
https://issues.jboss.org/browse/AS7-4547
Project: Application Server 7
Issue Type: Enhancement
Affects Versions: 7.1.1.Final
Reporter: Andrig Miller
Assignee: Andrig Miller
Fix For: 7.1.2.Final-redhat1
The standalone.sh script is detected the HotSpot JVM (Oracle JVM or OpenJDK JVM), and
setting -XX:+TieredCompilation. This setting slows throughput on performance workloads
such as our internal EJB 3 application, SPECjbb2005, and SPECjEnterprise2010, by some 3 to
5%.
