    ITRS Load Testing
    Ensure scalability on websites, apps and APIs. For the always-on enterprise. Control the ramp and bandwidth of over thousands of global virtual users and simulate real-world dynamics. Integrate with AppDynamics, New Relic, and Dynatrace to drill down, pinpoint critical issues, and identify root-cause. Measure the quality of user experience by viewing a stream of real browser render times and screenshots while tests run. Get feedback in real time, adjust parameters on the fly, and find optimal concurrency, breakage points and peaks. Consumer expectations are at an all-time high. Users demand a near instantaneous experience across all devices, and at all times. To compound this, business and IT leaders recognizes their mission-critical application stack is growing and becoming increasingly complex. When sluggish response times, performance bottlenecks, and full-blown website and application failures drive visitors away, the end result is lost revenue and reputational damage.
