• Analyze results with quick reporting
  While a load test runs, Loadster gives you realtime metrics on response times (average and percentile), network and transaction throughput, errors, and more
• After it finishes, the same data is instantly available in a test report you can hold on to or share with your team
• The metrics and report data inform you how your site handled the traffic, what kind of performance your real users can expect when the site's under a similar amount of load, and where the hot spots and bottlenecks might be
