Cycles render animation torture test?

I’m testing various configurations of a home render farm setup with GPUs and CPUs. To make comparisons easy I’ve been using barbershop, classroom, and junk shop stills, but I would like to do a torture test of a complex animation that will test the limits of my setup.
Are there any demo scenes out there that I could download for that?

Buy why? Only difference it will make is the i\o speed, if there will be very big and very many rendered frames. You can up the resolution if the existing scenes aren’t seem to be excessive enough

Testing the limits of a setup gives me peace of mind and insights. I have a few projects coming up where I want to be confident that I can throw anything at it at the resolutions that I will be using, and I’m not going to have errors, memory issues, waiting on I/O, etc. Most importantly, I want to run through a couple of 250-1000 frame renders and see that everything went well and performance was what I expected.
