Bug ID: 459413
Summary: Extraction of certain types of archives (tar.zst,
tar.Z, tar.lzma, tar.lz, tar.bz2) via context menu of
Dolphin is slower than extraction directly with Ark
Classification: Unclassified
Product: ark
Version: 22.08.1
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: elvis.angelac...@kde.org
Reporter: bugsefor...@gmx.com
CC: aa...@kde.org, rthoms...@gmail.com
Target Milestone: ---
SUMMARY
I noticed that sometimes extracting an archive via context menu of Dolphin
takes a long time.
Then I tried extract the same archives directly with Ark and surprisingly I
noticed that the extraction of certain types of archives is much faster,
sometimes taking about half the time. I did many tests extracting several types
of archives containing a 1 GiB video file, and here are the biggest
differences:
Extraction via context menu of Dolphin:
tar.zst 48s
tar.Z 1m20s
tar.lzma 3m17s
tar.lz 3m52s
tar.bz2 5m18s
Extraction directly with Ark:
tar.zst 26s
tar.Z 45s
tar.lzma 1m56s
tar.lz 1m55s
tar.bz2 3m04s
STEPS TO REPRODUCE
1. extract any of the following archives types via context menu of Dolphin and
then directly with Ark and pay attention to the time each extraction took:
tar.zst, tar.Z, tar.lzma, tar.lz, tar.bz2
2.
3.
OBSERVED RESULT
inconsistent performances depending on the way used to extract the archive
EXPECTED RESULT
same performance regardless the way used to extract the archive
