The performance measurements for the Medline 10 MB test scenario are shown in  Figure 7-13. The results for the Catalog 10MB document validation 10 replaces scenario are shown in  Figure 7-14. The results show a significant improvement in CPU and Elapsed time on every scenario when  comparing Db2 12 to Db2 11. In the scenario IBM Catalog 10MB with 10 replaces, a  comparable CPU time was observed, but the elapsed time reduction shows the advantages  that were introduced in Db2 12 for z/OS. 230  IBM Db2 12 for z/OS Performance Topics Figure 7-14 Catalog 10MB times Figure 7-13 Medline 10MB times
