How can I simulate a large audience and test the performance of PubNub for my app?

PubNub offers the PASS (PubNub Audience Simulation Service) to allow customers to experience and measure the performance of PubNub for their app. PASS is a tool where PubNub spins up tens or hundreds of servers to simulate any size of audience (up to millions of users).

PASS provides a realtime dashboard to view end-to-end latency and deliverability percentage. PubNub can also be configured to call your own servers with a REST call to acknowledge receipt of certain types of PubNub messages.
