I suspect that nginx would be able to handle this without at problem,
although I would suggest that the best way to find out is to do some
load testing. How are the responses built? If that involves database
lookups, for example, it's more likely that your bottleneck will be
there. Incidentally, I don't think XMLHttpRequest will help you - from
the server's point of view, it's just another request, albeit one
serving a smaller amount of data.
