PerfBeacon currently supports two ways of testing at any time (without a scheduler):
Using the API is covered on this page: Deployments.
Note that when triggering the API, the entire site will be tested. This means the combination of all pages, all regions, and all devices will be used.
You can also trigger tests at any time within a site by:
Queue Test, and a single test will run for only the specified page, device, and region.
