The Network panel records information about each network operation in your application, including detailed timing data, HTTP request and response headers, cookies, WebSocket data, and more. The Network panel helps you answer questions about the network performance of your web application, such as:

• Which resource had the slowest time to first byte?
• Which resources took the longest time to load (duration)?
• Who initiated a particular network request?
• How much time was spent in the various network phases for a particular resource?
