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
comparison tests, to determine if a degradation occurs between releases, and
release-to-release
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.
