Which two of the following factors are often responsible for poor Web application performance? (Choose two.)

HTTP request generation on the client side is a fast, local CPU operation and is rarely a meaningful bottleneck in overall web application performance.

Network delivery time is a dominant performance factor because bandwidth constraints, high latency, and packet loss all directly delay how quickly the HTTP response reaches the client, and this delay compounds across multiple resources on a page.

Browser rendering and display time, while measurable, is generally not considered a primary or dominant factor in poor web application performance when compared to network and server-side delays.

Server-side response generation time - encompassing database queries, application logic execution, and backend processing - is one of the most significant contributors to slow web application performance, as clients must wait idly until the server finishes producing the response.
