Yeah, something is clearly wrong here - if you haven't already, you might
use the express logger middleware to measure time spent server side
handling the request. Add something like this (this is what I'm using -
modify your desired fields accordingly) to the beginning of your express
app.use(_express.logger(':remote-addr [:date] ":method :url
HTTP/:http-version" :status :res[content-length] ":referrer" ":user-agent"
[ :response-time ms ]'));
You'll have to look at individual requests on your stdout, but at 2
requests a second, this shouldn't be too hard ;).
