Description Vladimir Omelchuk 2015-09-15 06:54:39 UTC 
/usr/bin/file from base very slow processes large text files (for example in Midnight Commander).

After removed /usr/bin/file and create link to /usr/local/bin/file (install from ports sysutils/file), MC again quickly open large files.

Timing for /usr/bin/file:
# time file /usr/ports/UPDATING 
/usr/ports/UPDATING: ASCII text
13.811u 0.007s 0:13.84 99.7%	20+173k 0+0io 0pf+0w

Timing for /usr/local/bin/file:
# time file /usr/ports/UPDATING 
/usr/ports/UPDATING: ASCII text

Comment 1 v.chernyadev 2015-10-23 14:07:31 UTC 
The problem is in /usr/share/misc/magic.
I replaced /usr/share/misc/magic* from older release and now it works fast.
Comment 2 Vladimir Omelchuk 2015-10-27 14:47:22 UTC 
What version FreeBSD you are used for replaced /usr/share/misc/magic*?
Comment 3 Vladimir Omelchuk 2015-10-28 09:34:09 UTC 
Even, if replaced files in /usr/share/misc/magic*,
this problem in the base system and it is not solved.

+re@ and secteam@

I think this is http://bugs.gw.com/view.php?id=474 and was fixed in later file imports (thus 10.3-RELEASE which is shipped with file 5.25).

It's not yet clear to me if this warrants an EN (as it's only complained by very few people), though, but that's an option.
Comment 5 Vladimir Omelchuk 2016-03-03 12:54:53 UTC 
Waiting fix in the 10.3-RELEASE ...
Comment 6 Vladimir Omelchuk 2016-03-05 01:04:16 UTC 
<uname>
FreeBSD 10.3-RC1 amd64

Timing for /usr/bin/file:
# time file /usr/ports/UPDATING
/usr/ports/UPDATING: ASCII text
0.214u 0.000s 0:00.21 100.0%	21+181k 2+0io 0pf+0w

/usr/bin/file working is fine!
Thanks!
