ShaoLin CogoFS (Cogo File System) is a high-performance and reliable stackable compression file system for Linux. It compresses files and stores them in compressed form to multiply your hard disk space, increases I/O access speed, and reduces network traffic.
ShaoLin CogoFS is designed for high performance, reliability, and easy migration. It also fills in the gaps for Linux, where there is no known stable compression file systems. Previous systems that performed compression and decompression with slow CPUs on virtual-volume compression file systems may have been slow and unreliable. ShaoLin CogoFS does not use virtual volumes, it presents compressed files in your existing file systems as normal files. Corruption risk is minimal because compression is done on individual files. As we know the speed of CPU has dramatically increased in the pass few years, decompression speeds can easily outperform most uncompressed disks transfer speeds with today's fast CPUs; because the compressed file system will significantly reduce actual data transfer to and from the physically-slow hard disk media.
