![]() So we decided to disable the text algorithm by default. Also its decompression speed is much lower than in general algorithm regardless of CPU number. RAR text compression algorithm cannot utilize several CPU cores efficiently, so its performance in multiprocessor environment is much lower than for general algorithm.General RAR compression algorithm allocates about 120 MB comparing to 40 MB in WinRAR 4.11 we had to increase memory requirements to achieve higher compression speed. Several cores are utilized more efficiently when compressing large files. Speed gain depends on data type and average file size. ![]() ![]() ![]() While some speed gain is possible even in single processor mode, best results are achieved in multi-core environment. RAR general compression algorithm is optimized for better utilization of several processor cores. ![]()
