On February 22, 2013, IBM® published a new SPECjEnterprise®2010
result on a two socket system. The result was achieved on the new IBM PowerLinux™ 7R2
system using IBM WebSphere® Application Server v8.5 and IBM DB2® 10.1 running on Red Hat® Enterprise Linux® release 6.4. The Linux Technology Center (LTC) team, the WebSphere team, the Java team, and the DB2 team all worked together to analyze and tune the performance of the hardware and software to produce the record-breaking result. A lot of the tuning and analysis has been captured as best practices in a new article, SPECjEnterprise: A performance case study
From the SPEC.org web site, "The SPECjEnterprise2010 benchmark is a full system benchmark which allows performance measurement and characterization of Java EE 5.0 servers and supporting infrastructure such as JVM, Database, CPU, disk and servers." The article contains many general use best practices that can be used on any system. If you are running a workload similar to SPECjEnterprise, the article may be especially helpful.
