We started our multi-instance workload testing in Test-2, as shown in the following figure, which included four SQL MIs: sqlmi-01 through sqlmi-04. Each of these ran four vCPUs and 8 Gi memory.
We observed that the TPM numbers for the sqlmi-01 instance when executing as part of a group are slightly lower compared with test one. This was expected behavior. The TPM numbers were still within an acceptable range considering the resources that were allocated and the running workloads.
For SQL MI specifications, see Test groups defined.
