Memory System Behavior of Java-Based Middleware

Java-based middleware, and application servers in particular, are rapidly gaining importance as a new class of workload for commercial multiprocessor servers. SPEC has recognized this trend with its adoption of SPECjbb2000 and the new SPECjAppServer2001 (ECperf) as standard benchmarks. Middleware, by definition, connects other tiers of server software. SPECjbb is a simple benchmark that combines middleware services, a simple database server, and client drivers into a single Java program.ECperf more closely models commercial middleware by using a commercial application server and separate machines for the different tiers. Because it is a distributed benchmark, ECperf provides an opportunity for architects to isolate the behavior of middleware. In this paper, we present a detailed characterization of the memory system behavior of ECperf and SPECjbb using both commercial server hardware and Simics fullsystem simulation. We find that the memory footprint and primary working sets of these ...
