While performance tuning a solution of @LordNeilLord, I came across a bug in designer. My use case was to create multiple ways to skin a cat and then to compare the timings of each run. I put each approach into its own container. To my surprise, I see messages in the results from containers that are disabled.

In the enabled container there are 0 filters and 0 summarize tools. The disabled containers are still executing logic.
Cheers,
