Hi Graham,

cf-acceptance-tests (cats) offers parallelization. The readme docs (https://github.com/cloudfoundry/cf-acceptance-tests#test-execution) explain how to configure this. (./bin/test -r -nodes=4)

Are you running cats in parallel? If so how many nodes are you running cf-acceptance-tests with?

The performance gain by running cats with multiple nodes is dependent on the resource capacity of the cf backend.

In our environments it typically takes ~45 minutes. We have successfully run cats in as little as ~20 minutes by running on multiple nodes.

Thanks
