Some idea? Use JMeter http://jakarta.apache.org/jmeter/ Run it from another machine in the same LAN if you can. easiest is to first create a proxy in jmeter that records the requests from the browser, configure the browser to use that proxy, access the layer preview through that browser and do what you expect a user to do, letting jmetter record the session. You can create a thread group in jmeter and tell its proxy to record all the requests that match a given mime type to go to that thread group. Beware with tiled requests the number of generated requests is gonna be large. Be sure to configure it to use http keep alive or you'll also be measuring HTTTP connect latency. Add an aggregate report listener as a sibling of the thread group, save the jmeter project file, and run it after each improvement with the number of threads you consider necessary. How to do all of that properly is on the jmeter documentation.
