In what situations is it justified to apply optimizations during data parsing?

Optimizations during data parsing are justified in situations where:

• A large volume of data is processed, and performance becomes a bottleneck.
• Parsing is performed on a device with limited resources (e.g., mobile devices), where saving memory and time is important.
• Parsing occurs in real-time or in the user interface, where delays are noticeable and degrade the experience.

In such cases, it is advisable to use more efficient algorithms, avoid redundant operations, apply streaming processing, or use parsers with low memory consumption.
