In addition to every possible caching, content delivery, network, and performance capability, Ethnio Intercepts can and should be limited to a narrow subset of your app or web visitors. The goal of Ethnio is to find the right participants for research, not bombard your infrastructure with needless requests.

Optimization & monitoring
We’ve been optimizing the performance, stability, and caching of our JavaScript for over five years now, with our JS being implemented on many of the largest sites and apps in the world. The average server response time for screeners is about 824ms. This time shows how fast Ethnio servers process requests and give responses.
