It is described in draft-miller-secsh-compression-delayed-00. A patented compression sleeve design allows Regular (dual), Tri, and Quad shield cables all to be terminated within a single connector. The underlying Deflater class lets you (which it calls, in the normal implementation), but since gzip adds extra header/footer/checksum information, you can't just use those classes directly (without duplicating GZIPOutputStream). Like & share :). On the compression side, GKL optimization of Java Deflater increased performance by a factor of about 1. This compression system is a very handy invention, especially for Web users, because it lets you reduce the overall number of bits and bytes in a file so it can be transmitted faster over slower Internet connections, or take up less space on a disk. Basic principles of Λ algorithm are the same as in FGK algorithm. LZO is a lossless data compression library that favors speed over compression ratio. Enabling gzip compression can reduce the size of the transferred response by up to 90%, which can significantly reduce the amount of time to download the resource, reduce data usage for the client, and improve the time to first render of your pages. you need a different library.
