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