Subject: Performance of "ls -F"
Date: Thu, 21 Jan 2016 18:10:00 -0000 [thread overview]
Message-ID: <loom.20160121T163405-489@post.gmane.org> (raw)
I am finding a large performance gap between plain "ls" and "ls -F" in a
directory with many files on a network share (NetApp disguised as NTFS if
that matters). This has been there for quite a while, I've just now
realized what the reason was (I have "ls -F" as an alias for "ls" in my
interactive shells). In a directory with 1300 files, a plain "ls" completes
in 0.3s, while "ls -F" requires about 95s. Determining the file class seems
to require around 70...90ms per file, which I can confirm also for
directories with a lot less files. What's involved in that determination
that takes such a long time?
Regards,
Achim.
