ZRAM compresses each page individually. As a result the compression algorithm is forced to use a very small sliding window. None of the available compression algorithms is designed to achieve high compression ratios with small inputs. This patch-set adds a new compression algorithm 'zBeWalgo' to the crypto api. This algorithm focusses on increasing the capacity of the compressed block-device created by ZRAM. The choice of compression algorithms is always a tradeoff between speed and compression ratio. If faster algorithms like 'lz4' are chosen the compression ratio is often lower than the ratio of zBeWalgo as shown in the following benchmarks. Due to the lower compression ratio, ZRAM needs to fall back to backing_devices mode often. If backing_devices are required, the effective speed of ZRAM is a weighted average of de/compression time and writing/reading from the backing_device. This should be considered when comparing the speeds in the benchmarks. There are different kinds of backing_devices, each with its own drawbacks. 1. HDDs: This kind of backing device is very slow. If the compression ratio of an algorithm is much lower than the ratio of zBeWalgo, it might be faster to use zBewalgo instead. 2. SSDs: I tested a swap partition on my NVME-SSD. The speed is even higher than zram with lz4, but after about 5 Minutes the SSD is blocking all read/write requests due to overheating. This is definitly not an option. Benchmarks: To obtain reproducable benchmarks, the datasets were first loaded into a userspace-program. Than the data is written directly to a clean zram-partition without any filesystem. Between writing and reading 'sync' and 'echo 3 > /proc/sys/vm/drop_caches' is called. All time measurements are wall clock times, and the benchmarks are using only one cpu-core at a time. The new algorithm is compared to all available compression algorithms from the crypto-api. Before loading the datasets to user-space deduplication is applied, since none Algorithm has deduplication. Duplicated pages are removed to prevent an algorithm to obtain high/low ratios, just because a single page can be compressed very well - or not. All Algorithms marked with '*' are using unsafe decompression. All Read and Write Speed Measurements are given in MBit/s zbewalgo' uses per dataset specialized different combinations. These can be specified at runtime via /sys/kernel/zbewalgo/combinations. - '/dev/zero' This dataset is used to measure the speed limitations for ZRAM. ZRAM filters zero-data internally and does not even call the specified compression algorithm. Algorithm write read --zram-- 2724.08 2828.87 - 'ecoham' This dataset is one of the input files for the scientific application ECOHAM which runs an ocean simulation. This dataset contains a lot of zeros - even after deduplication. Where the data is not zero there are arrays of floating point values, adjacent float values are likely to be similar to each other, allowing for high compression ratios. zbewalgo reaches very high compression ratios and is a lot faster than other algorithms with similar compression ratios.
