Workload C (100 percent read) operations were performed on all the Mongod VM by reading 20 million records on each Mongod VM. Each YCSB-mongo client reads a subset of the data, by changing the number of threads using the following command:
# ./bin/ycsb run mongodb -s -threads <number of thread> -P "workloads/workloadc" -p mongodb.url=mongodb://<hostname/IP>:27018/<database name>-p recordcount=200000000 -p operationcount=200000000
The following figure shows the PowerFlex storage IOPS results from (100 percent read) across all six Mongod VMs. A total of 156,500 read IOPS are achieved at submillisecond latency for 96 threads on the MongoDB cluster.
