modern compression algorithms capable to provide performances equal or

Comparison is conducted, in terms of compression / extraction speed and
compression ratio, against performances of Deflate ZIP in the range
from default to fastest compression settings.

input data is saved to system disk (PCIe SSD) and compressed to system
disk, same partition, separate directory; the resulting archives are
then extracted to
separate directory on same (system) disk/partition.
Each compression and extraction test is repeated 10 times to get an
average value; size is expressed in MB, time in seconds.
For each tested format, alhgorithm, and compression level, are used
default compression settings as
pre-set out of the box by the file archiver applications being tested
WinRar is chosen as reference for the fastest commonly available ZIP
Deflate implementation, due results of previous benchark tests.
Performance of ZIP Deflate is analized at normal and fastest
compression levels, and compared with non-Deflate algorithms at

Faster than zip
All alternative formats attained
better compression ratio results than ZIP Deflate at fastest
All formats (except for 7Z Brotli) attained better
compression ratio than ZIP Delfate at normal compression level, with
LZMA2 being the best compressor followed by RAR PPMd and Zstandard..
Faster than zip
compressed the input set significantly faster than
ZIP Deflate normal, and even faster than ZIP Deflate at fastest
7Z LZMA and RAR PPMd compression times are roughly comparable with ZIP
at fastest compression level (with RAR being faster), but both
vastly improved compression ratio.
7Z Zstandard and 7Z Brotli at normal compression level are
approximatively 3x times
faster than ZIP Deflate at normal compression level, 2.5x times faster
than ZIP Deflate fastest level.
Faster than zip
decompressed the benchmark data significantly faster than
ZIP Deflate, either compressed at normal or fastest level.
For extraction, 7Z LZMA2 at fastest level is nearly 2x faster than ZIP
Deflate, and slightly faster than RAR PPMd, reversing the performance
advantage RAR PPMd have in compression speed test.
7Z Zstandard extraction speed at all levels overlaps with 7Z LZMA2,
while 7Z Brotli provides significantly faster extraction, the fastest
of the test, nearly 4x faster than ZIP Deflate range of speed.
At minimum (1 on 9) compression level PeaZip with ARC format completed
compression test in 5.5 sec and extraction test in 2,7 sec, but created
a 447 MB archive which does not fall in the desired range, being larget
than the 429 MB output created by Deflate at minimum compression level.
At 2 on 9 compression level ARC completed the compression test in 15.3
sec creating a 310 MB archive, which is an excellent compression ratio,
outperforming all other alternatives, but extraction needed 28.4 sec,
almost 4 times slower than Deflate.
Due those drawbacks the ARC format was excluded from the test, but it
remains an extremely interesting archive format.
Deflate-based ZIP archives remains an excellent choice due the
ubiquitous support from file archivers and file managers (and built-in
support in many operating systems), it is no longer the better choice
New algorithms performs better on modern architectures and scales
better in performances on multicore machines, providing better results
in terms of speed, especially for extraction, and compression ratio.
What formats are faster
tha ZIP on modern hardware?
With WinRar, creating a RAR (PPMd algorithm)
at fastest compression level resulted
in a smaller archive AND took less time.
The same holds true with PeaZip with 7Z LZMA2 at fastest compression level,
extraction being almost twice faster than Deflate and even faster than
with RAR PPMd, a bonus that is especially
important for content distribution.
Switching 7Z compression to Brotli and Zstandard algorithms, which are
ground up designed for high performances, provides utter speed
improvements: both algorithms at normal compression level are able to
compete with ZIP Deflate in terms of compression ratio, but completing
the benchmark at almost
3 times faster compression speed.
provides a compression ratio even better than Deflate
normal, is twice as fast for extraction than ZIP Deflate.
provides a compression ratio intermediate from Deflate
normal and Deflate fastest, is almost 4 times faster for extraction
than ZIP Deflate.

- On modern machines using RAR or 7Z format at fastest
compression level provide faster compression, and especially faster
extraction, than using traditional ZIP format - even benchmarking
the fastest Deflate ZIP implementations and employing fastest
compression settings for Deflate.
- While being faster, both RAR and 7Z LZMA2 at fastest
compression level also provide significantly better compression ratio
than Deflate ZIP.
- New Brotli and Zstandard algorithms available in 7Z
provides further speed advantages over Deflate ZIP, while remaining
comparable or better in terms of compression ratio.
