First Byte Time

Enterprise Manager breaks down each transaction into individual phases. Performance metrics for each phase of the transaction can help you pinpoint the cause of a slow response time alert. This metric measures the First Byte Time, which is the total time taken between the last byte of the request sent and the first byte of the response received by the server for all requests made. This includes the network latency and the time for the server to respond.

As with the Connect Time and Redirect Time, this metric can help you pinpoint whether or not the page content or Web application software is causing the slow response time, as opposed to the actual time it takes to transfer one byte of information to the browser.
