Figure 5 Oracle 9.2.0.7 – Comparing two common LVM configurations with ODM
To allow a comparison of raw-on-LVM volumes and raw-on-VxVM volumes, the chart including CPU
utilization is shown in Figure 6.
The TPM levels off at about 49,000, with a user CPU consumption of 85% and system CPU usage of
14%. These values account for an approximately 4% increase in performance over the raw VxVM
configuration measured in Experiment 1.
