Brotli decompression is at least as fast as for gzip while significantly improving the compression ratio. NET offering the fastest LZF4, DEFLATE, ZLIB & GZIP implementations and LZMA & BZIP2 for maximum compression. Gzip uses the DEFLATE algorithm, combining LZ77-style substring matching with Huffman coding. 0 WinForms app that connects to a backend WAS server. If you require both speed and good compression, ZSTD is the best choice. These simple Python scripts benchmark different zlib compression libraries for the pigz parallel compressor. Block indexing utilizes gzip's FEXTRA feature which records the index of compressed members.

Jan 21, 2024 · I usually use gzip for compression, but I’m currently experimenting with the newer and more efficient zstd compression. Published as a support for golang/go#23154 Gzip Compression This test measures the time needed to archive/compress two copies of the Linux 4. NET in a C# program. Yet, pugz cannot decompress arbitrary gzip files. This suite is good for testing the system's processor, memory, and overall system performance. It re-quires the decompressed stream to only contain byte values 9–126. Both compression and extraction was timed. Bzip2 achieves better compression, but is even slower than Gzip. The brotli package is now on CRAN and In this article, we'll be showing compress + decompress benchmarks for 4 of the most popular Linux compression algorithms: gzip, bzip2 (using lbzip2), xz, and lz4 We'll lightly discuss the tradeoffs of each algorithm, and explain where/when to use the right algorithm to meet your (de-)compression needs :) ABSTRACT Gzip is a file compression format, which is ubiquitously used.

Jun 30, 2021 · To test the decompression performance, I uncompress repeatedly the same file. Compression Tests This test suite consists of tests that measure various forms of file compression such as gzip, bzip2, and 7zip. Compression and decompression performance gains are made by parallelizing the usage of block indexing within a gzip file. Jun 13, 2025 · Conclusion Based on the Performance Benchmarks, it seems ZSTD is the perfect choice when the Compression/Decompression times are of utmost importance, while Brotli takes the crown for Compression ratios. NET framework includes several classes that can be used to compress and decompress data, including the BrotliStream, GZipStream, DeflateStream, and ZLibStream classes. This technique can be combined with the CloudFlare zlib or zlib-ng which accelerates compression using other features of modern hardware. We have also discussed how to interpret the benchmark results and make informed decisions about compression algorithm choices. Feb 7, 2024 · Another option is zstd (default options), which will give you about the same compression ratio as gzip with ~10-fold faster compression and ~3-5-fold faster decompression. The gzip decompression is modified so it decompresses ahead of the current reader. Gzip, Bzip2 and XZ are popular compression tools, but which performs best? Here we benchmark them and compare the trade off between compression ratio and speed. . Go Compress/Decompress algorithm benchmark results Testing Golang's built in compression Zlib, Flate, Gzip and LZW CPU/Memory performance. bzip2 has notably better compression ratio than gzip, which has to be the reason for the popularity of bzip2; it is slower than gzip especially in decompression and uses more memory. , Linux source tarball), xz, brotli and zstd offers much better compression ratio compared to gzip or bzip2. pgzip is a multi-threaded gzip implementation for python that increases the compression and decompression performance. Now it’s between Zstd and LZ4. The benchmark currently consists of 36 datasets, tested against 40 codecs at every compression level they offer. The time-to-decompress flatlines for levels 7, 8, and 9 in the test results linked by Marcus Müller, though that's coarse-grained data given in whole seconds. In this blog post, I’ll be comparing the compression performance of gzip and zstd. Brotli is a new compression algorithm optimized for the web, in particular small text documents. While Gzip is widely used, it typically achieves lower compression ratios and slower speeds compared to Zstd. An important feature of this script is that each variant of zlib contributes compressed files to the testing corpus, and then each tool is tested on this full corpus. To run this test with the Phoronix Test Suite, the basic command is: phoronix-test-suite benchmark compress-7zip. NET 2. File compression and extraction benchmark. Benchmark Now that we know the difference between compression algorithms and archive formats, we can continue to the benchmark. Decompression in Gzip is fast but generally slower than Zstd. This next best case results in mostly Huffman-coding compressed data with only very few LZ77 back-references. I am using GZipStream to decode data coming back from a HttpWebRequest call made to the server. It computed the archive size to get the percent compression, then extracted the file to a temporary directory.

The data returned is compress Mar 19, 2024 · Facebook recently shared some benchmarks that show it performing signifcantly faster than gzip. Without any tweaking, I get twice the performance with zstd compared to the standard command-line gzip (which may differ from what your web server uses) while also having better compression. Because it is a relatively small file, we should expect disk accesses to be buffered and fast. Modern In this benchmark, two popular compression libraries, pako and fflate, are compared in terms of their gzip compatible compression and decompression capabilities. Beyond this, there’s also shared dictionaries for Brotli and zStandard, which have the potential to significantly reduce byte sizes. Fast compression benchmark. Further, while gzip compression can benefit from parallel processing, decompression does not. System GZIP Decompression: This test measures the time to decompress a gzipped tarball.
