• Onload (Sec): Onload time occurs when the processing of the page is complete, and all resources of the page have been finished downloading.
• TTDI (Time to DOM Interactive) (Sec): TTDI is the duration which is taken for a web page’s DOM to become fully interactive and responsive to user interaction.
• TTDL (Time to DOM Load) (Sec): TTDL is the duration which is taken for a web page’s DOM to be fully constructed and ready for user interaction.
• Server Response Time (Sec): This is the duration which is taken for a server to process a request and provide a response to user interaction.
• PRT (Perceived Response Time) (Sec): This refers to the subjective perception of how quickly a system or application responds to user interactions or requests.
• First Byte Time (Sec): This is the total amount of time spent to receive the first byte response once it has been requested.
• DNS (Sec): This is the decentralized hierarchical naming system that translates domain name into IP addresses, enabling users to access websites using human-readable addresses.
• SSL (Sec): This refers to the duration it takes for the establishment and completion of the Secure Socket Layer (SSL) handshake process, which establishes a secure encrypted connection between a client and a server.
