Fork of the repository inikep lzbench is an in-memory benchmark of open-source LZ77/LZSS/LZMA compressors. It joins all compressors into a single exe. At the beginning an input file is read to memory. Then all compressors are used to compress and decompress the file and decompressed file is verified. This approach has a big advantage of using the same compiler with the same optimizations for all compressors. The disadvantage is that it requires source code of each compressor (therefore Slug or lzturbo are not included).

usage: lzbench [options] input [input2] [input3]
where [input] is a file or a directory and [options] are:
-b# set block/chunk size to # KB (default = MIN(filesize,1747626 KB))
-c# sort results by column # (1=algname, 2=ctime, 3=dtime, 4=comprsize)
-e# #=compressors separated by '/' with parameters specified after ',' (deflt=fast)
-iX,Y set min. number of compression and decompression iterations (default = 1, 1)
-j join files in memory but compress them independently (for many small files)
-l list of available compressors and aliases
-m# set memory limit to # MB (default = no limit)
-o# output text format 1=Markdown, 2=text, 3=text+origSize, 4=CSV (default = 2)
-p# print time for all iterations: 1=fastest 2=average 3=median (default = 1)
-r operate recursively on directories
-s# use only compressors with compression speed over # MB (default = 0 MB)
-tX,Y set min. time in seconds for compression and decompression (default = 1, 2)
-v disable progress information
-x disable real-time process priority
-z show (de)compression times instead of speed
Example usage:
lzbench -ezstd filename = selects all levels of zstd
lzbench -ebrotli,2,5/zstd filename = selects levels 2 & 5 of brotli and zstd
lzbench -t3 -u5 fname = 3 sec compression and 5 sec decompression loops
lzbench -t0 -u0 -i3 -j5 -ezstd fname = 3 compression and 5 decompression iter.
lzbench -t0u0i3j5 -ezstd fname = the same as above with aggregated parameters
For Windows :
Start WSL using ubuntu
wsl
You will need to install gcc and g++.
Then, compile the application:
make
Once the compilation process is done, you can run the lzbench application by running :
./lzbench [filename]
More info about how to use the application are directly available in the following repository inikep REPO
