Trade 6 Primitives

Trade 6 provides an expanded suite of Web primitives, which singularly test key operations in the enterprise Java programming model. These primitives are very useful in the Rochester lab for

release-to-releasecomparison tests, to determine if a degradation occurs between releases, and what areas to target performance improvements. Table 6.1 describes all of the primitives that are shipped with Trade 6, and Figure 6.4 shows the results of the primitives from WAS 5.0 and WAS 5.1. In V5R4 a few of the primitives were tracked on WAS 6.0, showing a change of

0-2%, the results of which are not included in Figure 6.4. In the future, additional primitives are planned again to be measured for comparison.
