Re: Windows Server 2012 R2 - man very very slow

[Vilius Mockūnas]

Hello,

Yes fresh install and yes it happened on first man launch.
I checked processes - it's man.exe which waits.
And for example if man page not installed it takes 40s too:
$ man init
<<waits 40s before returning No manual...>>
No manual entry for init

Was this the first time you launched "man" (e.g. after a fresh
install)? If yes, was the next invocation of "man" also slow?

If you have Process Explorer (Microsoft TechNet), try running it while
issuing "man ls". You may be able to see which program is taking so
long to complete (man may start other programs).

Sounds like something locally installed is getting in your way.

The list is far from exhaustive. It only gives you an idea of how it is
a widespread problem, and what kind of software to watch for.
Your mileage may vary.

I have been troubled by the same problem for years.  I pinpointed the 
problem by running strace on the man command.  See the following excerpt.

00:00:03 [main] man 3120 stat64: entering
00:00:03 [main] man 3120 normalize_posix_path: src //man
00:00:03 [main] man 3120 normalize_posix_path: //man = 
normalize_posix_path (//man)
00:00:03 [main] man 3120 mount_info::conv_to_win32_path: 
conv_to_win32_path (//man)
00:00:03 [main] man 3120 set_flags: flags: binary (0x2)
00:00:03 [main] man 3120 mount_info::conv_to_win32_path: src_path //man, 
dst \\man, flags 0x2, rc 0
00:00:03 [main] man 3120 build_fh_pc: fh 0x612AE734, dev 000000C2
00:00:03 [WNetOpenEnum] man 3120 cygthread::stub: thread 'WNetOpenEnum', 
id 0x141C, stack_ptr 0xD1AD40
--- Process 3120, exception 000006ba at 7753C42D
00:00:05 [main] man 3120 __set_errno: int stat_worker(path_conv&, 
stat*):1923 setting errno 2
00:00:05 [main] man 3120 stat_worker: -1 = (\??\UNC\man,0x28AA70)

As you can see, man is trying to open a UNC (network) path to //man, 
which is a non-existent host.  The network timeout causes the delay.

I addressed the problem by adding the following in my .bash_profile file

export MANPATH=/usr/share/man

Those 45 seconds seem excessive whichever way I look at it, unless there
is quite some load on the filesystem that Cygwin is on.  In that case,
moving Cygwin to a different disk or investing into an SSD might be your
samrtest investment in ages.  But if it is not that, try if running

mandb -c

helps those display times.  Note that this will likely take quite some
time to run, maybe even hours, on your system.

Achim.

Windows Server 2012 R2 - man very very slow

[Vilius Mockūnas]

Hello,

Windows version:
Windows Server 2012 R2 Standard (x64)

Cygwin version:
$ uname -a
CYGWIN_NT-6.3-WOW64 host1 1.7.33-2(0.280/5/3) 2014-11-13 15:45 i686 Cygwin

man displays man pages very slowly - for example "man ls" takes about 45s to 
display.

Any ideas ?

thanks,
Vilius M
