Interpreting performance statistics for NexJ CRM
Performance statistics display request and response metrics for the user, providing detailed information on browser-to-server requests in real time.
Use this functionality to identify network and environment issues in your application deployment. This helps application developers and quality assurance analysts understand potential performance bottlenecks, detect performance regressions, and investigate environment issues such as database performance.
As of NexJ CRM 9.4, application developers, solution architects, or QA analysts, can click the Show available actions floating action button in the bottom-left corner of the user interface to display the summary of server, network, and client performance statistics.
The following screenshot shows the floating action button and the available statistics:
The value displayed in each property label is the maximum value of the last 10 summarized entry values for that property.
The numbers displayed on the labels are rounded to the nearest integer above them, however for numbers less than 10 the values display one decimal digit.
If the user is curious to know more details about the performance statistics for each event, the user can click More Details to open the Performance statistics dialog that contains further details. The Performance statistics dialog contains the following information.
