Breaking down the load time of a web page into coherent components

A tangible, non-transitory, computer-readable medium storing program instructions that cause a computer to execute a process comprising:

• monitoring timing of navigations and resources of a web page load;
• attributing timing of static first-party resources and timing of hypertext transfer protocol (HTTP) redirects to a core frontend timing component;
• attributing timing of dynamic first-party resources to a core backend timing component;
• attributing timing of content delivery network (CDN) resources to a CDN timing component;
• attributing timing of non-CDN third-party resources to a third-party timing component;
• attributing timing of network infrastructure connections to a core connections timing component;
• and
• performing one or more actions based on the attributing steps.

An apparatus, comprising:

• one or more network interfaces to communicate with a network;
• a processor coupled to the network interfaces and configured to execute one or more processes;
• and
• a memory configured to store a process executable by the processor, the process when executed configured to:
• monitor timing of navigations and resources of a web page load;
• attribute timing of static first-party resources and timing of hypertext transfer protocol (HTTP) redirects to a core frontend timing component;
• attribute timing of dynamic first-party resources to a core backend timing component;
• attribute timing of content delivery network (CDN) resources to a CDN timing component;
• attribute timing of non-CDN third-party resources to a third-party timing component;
• attribute timing of network infrastructure connections to a core connections timing component;
• and
• perform one or more actions based on the attributing steps.
