Dynamic vs static compression ratio

WebAug 15, 2024 · Compression is a CPU-intensive process, and the more you compress a file, the longer it takes. Because of this, gzip offers a range of compression levels from 1 to 9; 1 offers the fastest compression speed but at a lower ratio, and 9 offers the highest compression ratio but at a lower speed. The gzip application uses level 6 by default ... WebApr 5, 2013 · It’s important to make a distinction between static compression ratio and dynamic compression ratio. The static compression is what you measure on an engine stand with a burette and graduated cylinder. It’s a simple mathematical comparison between the volume above the piston at the bottom and top of its travel.
