## Operator Performance Overview
### cold start - initial cluster creation
This test would assess the duration and efficiency of initializing the first cluster,
which typically takes longer due to initial setup tasks such as pulling images and configuring the
environment. The test aims to capture the performance impact of these one-time operations to understand
the startup behavior and identify potential areas for optimization.

### n(=${{ env.N_SIMUL_CLUSTERS }}) simultaneous cluster creation
This test is creating multiple clusters simultaneously in operator deployments of varying number of concurrent
workers to help us understand how the operator manages high load in restricted environments.
