Tuning WebSphere Application Server Cluster with Caching The paper is available at:
TecDocs: http://www-03.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/WP101406 developerWorks: http://www-128.ibm.com/developerworks/linux/linux390/perf/tuning_pap_websphere.html#wascc This paper analyzes parameter and configuration variations in a WebSphere® Application Server cluster running the Trade workload when caching is enabled. A secure environment was used with a DMZ to protect the application servers against an uncontrolled external zone. The findings include: Any form for caching resulted in a significant throughput improvement over the no caching case, where Distributed map caching gave in the highest throughput improvement. Dynachache disk-off load can significantly improve the performance with small caches without additional CPU cost. The z/VM® VSWITCH LAN configuration resulted in higher throughput than the Guest LAN feature. The IBM® System z10® system obtained a significant throughput advantage over the IBM® System z9® system They highly recommend z/VM for environments like this.
