BlazeMeter provides three sets of reports covering every performance aspect:

• Load report include aggregated and detailed load measurements as reported by JMeter .
• Errors report details all errors that were encountered.
• User-experience report including browser render-time measurements as reported by an automated Firefox browser. This report also includes a complete waterfall breakdown of the entire requests/response sequence as perceived by a real browser during the load period.
• Page Speed optimization report according to Google’s Page Speed standard. This report ranks your page speed performance aspects and also provides numerous recommendations as how to optimize your page speed to receive better search engine ranking.

Most of these reports are available only through BlazeMeter and not through the regular JMeter interface.

Although JMeter does support few graphic reports through the regular interface it is not recommended to enable them as they consume a lot of memory and will result in the console freezing under heavy load. Use the above mentioned reports instead. They have no affect on JMeter during the test run and are accessible after the test had ended.
