Twitter seems to really rag on rails but at the end the graph looked pretty good to me for their old architecture at the 95th percentile given their traffic.<p>Most sites won't even get 200 reqs per second total, and it's great to know that rails can pump that out on a single machine for a non-trivial app.<p>200 * 60 = 12,000 reqs per minute<p>12,000 * 60 = 720,000 reqs per hour<p>720,000 * 24 = 17,280,000 per day
