I believe that at some point you may want to include also rich parameters as they cause more DB calls in total (worst case scenario).

Yep, that would be a good test for load related to concurrent workspace builds.
For the moment though, I'm going to keep it simple with zero parameters.

- To generate workspace traffic, run `./coder_trafficgen.sh <name of loadtest from your Terraform vars>`. This will keep running until you delete the pod `coder-scaletest-workspace-traffic`.

1. When you are finished, you can run `terraform destroy -var-file=override.tfvars`.
