Lux's built-in multi-threaded download engine is its core technological innovation, and 2-16 working threads can be configured through the parameters. Test data shows that under the same network conditions, the 8-thread download speed is increased by 300-500% compared with the traditional single-thread, and the CPU occupancy rate is kept within a reasonable range.
The technology uses an intelligent chunking algorithm that automatically calculates the optimal chunking strategy based on the size of the video file. During the download process, the progress of each thread is dynamically monitored, and if a thread gets stuck, it will automatically reassign the task. What's more, Lux's multi-threaded module implements a perfect error handling mechanism, which does not interrupt the whole process when a single thread fails to download.
In practice, for HD video files over 1GB, multi-threading technology can save more than 60% download time. Meanwhile, it supports bandwidth limiting function, and the download rate can be precisely controlled by the -speed-limit parameter to avoid affecting other network applications.
