shopping application, but would provide even better response times than the 270-2423 as projected in
Figure 11.3.
When using MHz alone to compare performance capabilities between models, it is necessary for those
models to have the same processor technology and configuration. Factors such as L2 cache and type and
speed of memory controllers also influence performance behavior and must be considered. For this
reason we recommend using the tables in Appendix C when comparing performance capabilities between
iSeries servers. The data in the Appendix C tables take the many performance and processor factors into
account and provides comparisons between the iSeries models using three different metrics, CPW, CIW
and MCU.
