In Test-1, which we used as a baseline, we deployed and ran our HammerDB test harness against a single SQL MI, sqlmi01. The TPM results are shown in the following figure. TPM scaled at a near linear fashion without saturating the underlying infrastructure as we incrementally added HammerDB virtual users. We observed about a 40,000 TPM increase as we progressed through our first three user sets. TPM increased by about 20,000 for the last user set.
For SQL MI specifications, see Test groups defined.
