Figure 7 shows the combined results of the DataStax Enterprise benchmark tests for the read-intensive, write-intensive, and balanced read/write scenarios on the Red Hat OpenShift cluster configured with Intel Optane PMem. The x-axis displays the total throughput in operations per second performed during each test’s 10-minute run, while the y-axis displays the mean latency in milliseconds for each operation during the run.

Figure 7. Benchmark results for the DataStax Enterprise read-intensive, balanced read/write, and write-intensive scenarios on the Red Hat OpenShift cluster configured with Intel Optane persistent memory

The Red Hat OpenShift cluster test consisted of six test runs for each read-intensive, write-intensive, and balanced read/write scenarios. Each data point on the chart represents a test run with a specific number of client threads that simulate client loads. The number of client threads for each test run were:

• First test run: 20 client threads
• Second test run: 80 client threads
• Third test run: 160 client threads
• Fourth test run: 320 client threads
• Fifth test run: 640 client threads
• Sixth test run: 960 client threads

Figure 7 shows that latency moderately increased for both the 90 percent read/10 percent write scenario and the mixed 50 percent read/50 percent write scenario. The latency showed a more dramatic increase in test four in the 10 percent read/90 write scenario. The maximum operations per second occurred with the 10 percent read/90 percent write workload at 203,099 with 960 client threads.
