Compression is valuable for boosting speed, especially for users on mobile devices or limited data plans, as it minimizes data consumption.Compression algorithms detect repeated patterns in data to reduce redundancy and shrink payloads while maintaining content integrity.Implementing compression in ASP.NET Core involves enabling Response Compression middleware for sending compressed responses.Clients must indicate support for compressed responses via the Accept-Encoding header in the request.Server compression algorithms like gzip, deflate, or br are used based on client preferences to efficiently compress data.Compression negotiation gives clients control over data receipt and allows servers to respond effectively.Enabling compression in APIs significantly reduces payload sizes for faster data transfer and efficiency.Compression savings can exceed 99% of original size, benefiting users on limited data plans by saving bandwidth.Optimizing compression levels depending on payload type and content is essential for best results.Compression may not be beneficial for very small payloads due to overhead, so testing different scenarios is crucial.
