A method for real-time analysis of results from a load test performed on a target website includes periodically computing first-level aggregated test results within each of a plurality of load server instances that generate a load on the target website. The first-level aggregated test results are computed from data received by each of the load server instances from the target website every first time interval. The first-level aggregated test results are then periodically sent from each of the load server instances to an associated one of a plurality of analytic server instances every second time interval. The first-level aggregated test results are aggregated by each of the analytic server instances to produce second-level aggregated test results, which test results may then further aggregated to produce third-level aggregated test results at a data storage instance in real-time.
