In a well documented post on how he achieved improved performance on a SPARC T4-2 Server Jeff Taylor explains that, as a result of running a Java EE Application Server Cluster by deploying the cluster members into Oracle Solaris Containers and binding those containers to cores of the SPARC T4 Processor, both throughput and response times improved appreciably. The post includes both "before" and "after" results of tests with and without processor binding.

How Memory Allocation Affects Performance in Multithreaded Programs [25732]
Sniffing Out Lock Contention with Several Tools

If your new server has an alarmingly lower transaction rate than you had anticipated, Rickey C. Weisner suggests that you look first at lock contention in the memory allocator. His article demonstrates the use of prstat to determine whether there is lock contention. Demonstrated as well is the use of Professor Emery Berger's MT-hot allocator named Hoard, and of the mtmalloc (both old and new), and the libumem memory allocators. The question of which is best is answered by Weisner's use of a test harness, which appears to give the edge to the new mtmalloc.
