Latency and requests per second are not the same thing. Especially in a system like node where you can have thousands of concurrent requests going on at once. Typically, the more concurrent requests, the slower each request gets.
Node can probably handle this load given the right coding and clustering. If the machine is fast enough and the request simple enough, a single process can almost handle it. This problem is exactly the type of thing that node is well suited for.
