Выполнен анализ эффективности скоростных характеристик сжатия данных файловой системы Btrfs ядра Linux. Предложен алгоритм оптимизации выбора данных для сжатия в режиме реального времени. Описанный алгоритм с допустимой точностью дает ответ на вопрос— необходимо ли сжимать данные. Это позволяет значительно сократить использование вычислительных мощностей. Определены основные характеристики производительности описанного алгоритма.</p></abstract><trans-abstract xml:lang="en"><p>The article deals with the problem of the efficiency of data compression algorithms. The analysis of the effectiveness of the speed characteristics of data compression of the Btrfs file system of the Linux kernel has been performed. An algorithm for optimizing the choice of data for real-time compression is proposed. The described algorithm gives the answer with an acceptable accuracy whether it is necessary to compress the data. This can significantly reduce the use of computing power. The main performance characteristics of the described algorithm are determined.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>технологии хранения данных</kwd><kwd>сжатие данных</kwd><kwd>Btrfs</kwd><kwd>Linux</kwd></kwd-group><kwd-group xml:lang="en"><kwd>data storage technologies</kwd><kwd>data compression</kwd><kwd>Btrfs</kwd><kwd>Linux</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Трубачева, С.
