Sounds like ATS should be able to keep up with that work load. However, I've not worked with httpress specifically, so I'm not certain what kind of RPS those arguments would correspond to..
How did your ATS box fail? Did it crash? Did it just get so slow that the requests started timing out? Is your request mapping through to an origin? Or hitting cache? I would start looking at memory usage. If ATS starts swapping, things go downhill fast. If you are caching, how much ram cache do you have configured? If you aren't caching, does you configuration still have ram cache enabled?
