The 7z LZMA benchmark runs dummy compression and decompression tasks to measure the overall performance of the system. It reports measurements in MIPS (million instructions per second) which give an idea of the computer’s raw processing power counting all factors. 7z LZMA compression is a multi-threaded work-load. This means that it can utilise multiple cores… Read More »
