ZRAM Will See Greater Performance On Linux 5.1 - Phoronix

WebThe LZ4 algorithms aims to provide a good trade-off between speed and compression ratio. Typically, it has a smaller (i.e., worse) compression ratio than the similar LZO algorithm, which in turn is worse than algorithms like DEFLATE. However, LZ4 compression speed is similar to LZO and several times faster than DEFLATE, while decompression ...

zram, formerly called compcache, is a Linux kernel module for creating a compressed block device in RAM, i.e. a RAM disk with on-the-fly disk compression. The block device created with zram can then be used for swap or as general-purpose RAM disk. The two most common uses for zram are for the storage of temporary files (/tmp) and as a swap device. Initially, zram had only the latter function, hence the original name "compcache" ("compressed cache"). Web0: Original version 1: LZO-RLE. Version 1 of LZO implements an extension to encode runs of zeros using run length encoding. This improves speed for data with many zeros, which is a common case for zram. This modifies the bitstream in a backwards compatible way (v1 can correctly decompress v0 compressed data, but v0 cannot read v1 data).
