# Startup timing: SessionFactory build time (nanoTime, ms), 3 runs per database.
# Measured in a shared sandbox container -- NOT a benchmark, indicative of relative order of
# magnitude only. The first H2 run includes JVM/driver class-loading overhead common to
# whichever database happens to run first in the JVM.
