Hi Larry,

plese find cygcheck.out attached in the mail I sent 1 minute ago named
"Blue Screen after ejecting CD". 

(I replaced my username and PC-name with <USER> and <PCNAME> in the log.)

Thanks for looking into all this.

Paul

I see a couple of things that you could look at from this output.

First, there are the potential app conflicts.

   Potential app conflicts:

   Sonic Solutions burning software containing DLA component
   Detected: Named process.

   ByteMobile laptop optimization client
   Detected: Named file.

I'd trying removing (uninstalling and rebooting) Sonic Solutions DLA.  If
that works, then you've found your problem.  You may be able to get partial
functionality back there by reinstalling but deactivating the DLA feature.  I
don't know for sure.  In any case, you should report this problem to the
vendor.

Second, and I think most likely, is the ByteMobile stuff itself.  I expect
this is what you're using to connect to your mobile network, so I also expect
that removing it will solve your problem.  But then again, if I am right,
you won't be able to use the mobile network that allowed you to see the
problem in the first place so....  But it's probably worthwhile to report
the problem to that vendor as well.  It's listed on the BLODA list because
it's been reported as interfering with proper Cygwin operation before.

Third is the orphaned installation you have in "D:\Programme".  I doubt
this is a contributor but since it's an easy thing to clean up, it's worth
a shot.

The best thing to do is to skip any flags for 'ls'.  If cygwin has to open
the file to fill in a particular piece of data, you're going to see significant
delays on a slow file-system/driver.

How to make "ls" as quick as a Windows "dir"?

[Paul Maier]

Hello,

for my cygwin installation (cygwin-1.7.7-1, downloaded 2010-11-02, on a Windows XP SP 3),
the time for a "ls -l" to complete is much slower than the time for a "cmd /C dir",
although similar information gets displayed.

Does anybody know a setting, maybe a flag to "ls", to make the ls as quick as the Windows dir?


On a local drive, both, ls and Windows dir, are quite quick. The difference comes up,
when working on a slow network drive (Q:).

I took these times:


Example 1: Windows dir completes in only 13.3 seconds 
-----------------------------------------------------

/cygdrive/c/Dokumente und Einstellungen/test2/Desktop/cy>time cmd /C dir 'Q:\Angebot'
 Datenträger in Laufwerk Q: ist Data
 Volumeseriennummer: XXX

 Verzeichnis von Q:\Angebot

04.02.2011  21.10    <DIR>          .
04.02.2011  21.10    <DIR>          ..
03.02.2011  14.29           775.168 AnXXX
03.02.2011  13.50           231.936 EAXXX
28.01.2011  10.11            60.928 PrXXX
               3 Datei(en)      1.068.032 Bytes
               2 Verzeichnis(se), 880.856.702.976 Bytes frei
0.015u 0.015s 0:13.33 0.1%      0+0k 0+0io 1219pf+0w



Example 2: cygwin ls takes 53.9 seconds
---------------------------------------
For the same drive and same directory, Cygwin's ls takes 53.9 seconds,
that's 4 times as much than the Windows dir:

/cygdrive/c/Dokumente und Einstellungen/test2/Desktop/cy>time ls -l /cygdrive/q/Angebot/
insgesamt 816
---------- 1 ???????? mkgroup 775168  3. Feb 14:29 AnXXX
---------- 1 ???????? mkgroup 231936  3. Feb 13:50 EAXXX
---------- 1 ???????? mkgroup  60928 28. Jan 10:11 PrXXX
0.030u 0.077s 0:53.91 0.1%      0+0k 0+0io 2026pf+0w


Does anybody have an idea?

Thanks
Paul
