testRTC can get to high number of probes count for its testing service. That said, since we use real browsers that require multiple CPU cores to work effectively at large scale, this becomes expensive at times.
There are two ways to scale beyond a few 1,000’s of probes in a single test efficiently:
- Voice only. For voice only tests, you can open multiple tabs in the browser of each probe, getting more density. From our experience, you can expect anywhere between 4-8 tabs to be opened in parallel per probe before the audio bitrate becomes a bit unstable
- Video testing. For video testing at higher scales, our suggestion is to use testRTC with anywhere between 100-1,000 probes while running synthetically generated traffic towards your media servers using other tools. For more on how to achieve that, contact us directly
