## 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(=3) simultaneous cluster creation | |
Creating simultaneously to check if operator is able to manage the load of creating multiple clusters | |
at once. Creating multiple clusters simultaneously, in operator deployments; of varying number of concurrent | |
workers help us understand how the operator manages high load in restricted environments as well. | |
