bash very slow in cygwin 1.7.16-1 Win7/64 bit

bash very slow in cygwin 1.7.16-1 Win7/64 bit

[Adam Rosi-Kessel]

Cygwin used to run very quickly for me; now it doesn't. Not sure when it 
stopped -- last few weeks.

# time for i in {1..5} ; do bash -c "echo Hello" ; done
Hello
Hello
Hello
Hello
Hello

real    0m51.451s
user    0m0.230s
sys     0m0.979s

# time ls | wc -l
21

real    0m10.231s
user    0m0.030s
sys     0m0.264s

The system should be fast enough:

- Windows 7 / 64-bit fully patched
- Quad core CPU
- 8 GB RAM
- nothing else running
- Everything on solid state disk

This problem seems to have many different causes. Here is what I've 
tried so far with no success at all:

- Uninstall bash_completion
- Move .bashrc / .bash_profile out of the way
- Running in xterm
- setting PS1 to '$'
- unmounting all network drives
- unsetting the path
- adding '127.0.0.1 localhost cygdrive wpad' to 
c:\windows\system32\drivers\etc\hosts
- running as administrator

Any suggestions for further things to try?

if the SkyDrive is trademark of M$ and if it needs network connection to 
remote server, it would piss you off like you have been experienced.
If it is the case, please stop using *Skydrive* mounted directory as 
home directory for specific user of cygwin unless your network 
connection is faster than your hard drive and it isn't that fast for 
sure according to your complaint.

SkyDrive is not a network-mounted directory. Instead, it is a local
directory that is periodically synced to the cloud. But you can have
no network access at all and it works fine. Indeed, when running
cygwin offline (no network) I get the same result. Also, if I change
my home directory to something that is not synced to the cloud (e.g.
just c:\) I get the same slowness.

I have been keeping my home directory in SkyDrive for a while so I
have the same home directory across multiple devices. The slowness is
only recent, long after I started using SkyDrive.

Another data point: I just did a completely fresh (i.e. from scratch)
local drive bare-bones installation (just shell, coreutils, etc) into
a new directory. Exact same slowness.

You've not excluded any other changes in your environment.  What
network mapped devices do you have?  Are they still available.  If not
the system will wait for the network timeout to occur before moving to
the next device.

Did you at least try chainging your ${HOME} to somewhere normal and 
seeing what happens?  Perhaps SkyDrive has some feature that makes 
Cygwin crazy.  For example, your cygwin could have inotify listeners on 
${HOME} which could be somehow accidentally triggering SkyDrive's 
"refresh the pretty icons" mechanism which could be tickling the inotify 
listeners which could be somehow accidentally triggering SkyDrive's 
"refresh the pretty icons" mechanism which could be tickling the inotify 
listeners which could be somehow accidentally triggering SkyDrive's

Same slowness when I disconnect all network drives; disconnect the
network; unset all environmental variables except PATH which I set to
/usr/bin and HOME which I set to /.

Thus, when I go to Explorer (in Windows) I see only local drives.

Also, nothing has changed in the network environment in the past year or so.

Yeah, I tried setting ${HOME} to /cygdrive/c and "c:\" and even just
"/" with no change in results.

I don't know if this has anything to do with your problem, but I 
wouldn't call any of these settings of $HOME "normal".  I think most 
people leave $HOME unset, in which case it gets set to /home/username 
during a Cygwin session.

Yes, I uninstalled the completion package entirely. (also scrubbed it

At least in my experience, standard cygwin install doesn't create
anything under /home. But, yes, I've also unset $HOME. No difference.

I also tried a brand new install into a new directory with default
settings, both of 1.7 and legacy 1.5. Still no difference (1.5 is
actually even slower).

In a standard Cygwin install, the script 
/etc/postinstall/000-cygwin-post-install.sh runs 'mkpasswd -l -c > 
/etc/passwd', which sets the home directory for each user.  Normally 
this is /home/username, but you can check it by looking at /etc/passwd. 
  Then the first time you start a shell, /etc/profile creates the home 
directory (as specified in /etc/passwd) if it doesn't exist.  This 
assumes that HOME is not set in the Windows environment.  Are you seeing 
something different?

Yes. I just installed from scratch -- download setup.exe and specify a
new directory for install; then installed only bash and its
prerequisites. When I run the default cygwin.bat in the new directory,
I get:

bash-4.1$ pwd
/usr/bin
bash-4.1$ echo $HOME
/home/avk
bash-4.1$ cd
bash: cd: /home/avk: No such file or directory

I've had a similar problem about a year ago.  The symptom was that each
command from Cygwin would make lsass.exe max out one CPU for about one
or two seconds; during this time nothing else would happen as far as
Cygwin was concerned.  I never found out what was really responsible (I
suspect a botched group policy), but you might want to check this in
process explorer.

And in any event, if I then mkdir /home/avk, even in my fresh install,
cygwin is still extremely slow.

So it appears that /etc/profile is not being run, since it would give 
you the message "/home/avk could not be created" if it tried and failed 
to create /home/avk.  Also, it would set PS1, giving you a different 
prompt than the one above.  I don't know what might cause /etc/profile 
to fail to run.

BTW, cygwin.bat is no longer the recommended way to start a Cygwin 
shell.  If you ask setup.exe to create a shortcut, it will create one 
that starts mintty.  But I doubt if this is related to your problem.

Two people in this thread have suggested that you check for BLODA, but 
you haven't responded to that.  Also, you haven't yet attached cygcheck 
output as requested at

NT Domain victims often have %HOME% set by administrative policy -- if 
it isn't set with an explicit policy/setting then I believe Cygwin will 
use %USERPROFILE%, which is pretty ghastly ... but surely this has been 
the subject of several bitter flame wars already and was determined to 
be the most reasonable compromise available for whatever reason...

Plus, I can just change the source and recompile if I don't like it :) 
And it's off topic :)

Speaking of which.  Adam, I know you have tried to rule this out, but I 
can't help but continue to suspect your LiveSkyThingy... do me a favor, 
just to shut me up, will you?

Step one, make backups.   I mean it!

Now, using Windows Exploder (maybe don't use Cygwin), please create a 
C:\Harmless, folder, if possible with Everyone->Full Control access 
rights and preferably owned by you (do this by unchecking "Use Sharing 
Wizard" in Explorer's options dialog under the View tab and using the 
classic NT4 dialogs).

iow: make sure there is nothing spooky about that folder.

In wordpad.exe, edit your cygwin's /etc/passwd to contain 
/cygdrive/c/Harmless as your home directory instead of /c/LiveThingy... 
make a note of the old setting.

Go into your profile settings (Right Click "My Computer" -> Manage; then 
drill down in the tree-view to Computer Management->System Tools->Local 
Users and Groups->Users.

In the right hand side you will see the various accounts on your system 
-- go to yours, open it up, go to the "Profile" tab.  Make a note of the 
current settings (maybe take a screen shot).

Now: are you the only administrator account on the system?  If so, add 
another one (he needs to be an administrator with a password).  Now, log 
out -- that's done with the button labelled "Log Out" in your Start menu 
-- and log in as that Administrator account (this doesn't have to be 
"the" Administrator account and, indeed, probably shouldn't be) and 
repeat the above rigamarole to get back to the same "User Accounts" 
dialog.  Go to your account -- not the one you just created and logged 
in as, but the one you actually use in real life.   Double click 
yourself, so to speak, and open the "Profile" tab.

If your "Profile Path" is on C:\LiveSkyThingy, change it to C:\Harmless. 
  and set the Home folder radio button to "Local Path" and set that, 
also, to C:\Harmless.  This will create exactly the situation I was 
bitching about at the beginning of this post, which is fine for our 
present purposes.

Then, close the dialog box, (using "OK"), and right click your favorite 
"My Computer" icon again (actually I guess it's just 'Computer' these 
days).  Go to "Properties" -> "Advanced System Settings" (on the left) 
-> [the "Advanced" tab] -> press the Environment Variables button, and 
remove any HOME variable setting you see there, both global and per-user.

Finally, if your account is a Domain account, please please please 
change it to a Local one using this recipe:

http://support.microsoft.com/kb/312138

Otherwise, there is a very real risk of nuking your roaming profile!!

Now, Reboot.  Log in as yourself.  You will get a blank profile.  Don't 
panic, everything will come back once you reverse the above steps :)

If that doesn't get you a reasonable cygwin... well, then, almost 
certainly LiveSkyThingy is not the culprit.  Unfortunately, if it does 
fix the problem, you still can't say whether LiveSkyThingy is at fault 
because everything in your HKEY_USER registry is wiped clean by the above.

One note:

Carefully reverse all the above steps to get your profile back... if you 
are in a Domain environment... do it VERY carefully, again, so as not to 
blow up your roaming profile.

Other things you could check:

have you frobbed your LSA thingy lately? frob it.

rebased lately? rebase.

$ strace /bin/bash -l -c 'echo whee!' 2>&1 | sort -h > \
     /cygdrive/c/strace.log

stop every cygwin process but /bin/ash (no mintty, X, or services)... 
still slow?

reinstall cygwin in-place
"         "      from scratch

chkdsk

sfc /scanonce

buy a new computer and run linux on it

...etc

:)

OK, now this is strange -- I thought I had checked BLODA (responded in
separate thread about ESET), but just now I killed a bunch of things
in my systray, and suddenly cygwin was fast again. Then I restarted
all of the tasks I had killed, and it's still fast. Will do some more
digging to see if I can even get it to be slow again -- but it has
been slow for a few weeks, throughout reboots.

So after a reboot--still fast. This is after a month or so of
slowness. But I didn't change anything about my configuration!

Now I'm really confused.

cygwin was very slow -- then I killed Dropbox, and it sped back up.
But after a while it reverted to slow again (without Dropbox
restarting). I've repeated this behavior with a few other tasks--same
thing happened with Google Desktop and Skydrive. I'm not sure it
actually matters which task I kill -- but killing them will speed
things up for a bit and then it seems to revert to very slow again,
even if the tasks aren't restarted.

Can anyone offer a way to narrow/isolate the cause here? Is the above
behavior consistent with any hypothesis?

Was running very slowly; just closed Google Chrome and it got fast
again. Then re-opened Chrome and slow again. So it really doesn't seem
to matter what program it is.

May I ask if you bothered to check Task Manager (or better yet Process 
Explorer) to see what's running and what's consuming resources? It seems 
like the natural step to the question of slowness. In general it's 
usually one or more of 1) CPU, 2) Disk activity 3) Memory exhaustion 
(common) or 4) Network slowness or excessive network access.

I took an IQ test and the results were negative.

This suggest that you're looking into wrong direction, and real culprit is
something you didn't caught yet.
Try HijackThis http://sourceforge.net/projects/hjt/ to see if there's any
suspicious handlers installed in your system.
Or you may send the logfile to me (off-list!) and I'll try to look for clues
myself.

I think I've found the culprit! "Browser Manager"

http://www.explosiveknowledge.net/main/2012/08/19/browsemngr/

This was a bear to get rid of, but I believe cygwin is back to full
performance now.

I'm usually very good at avoiding adware; somehow this one slipped
through the cracks.
