DISM Sloowwwww

General discussion

So, I've had to upgrade my Windows WIAK to start using it with server 2008 R2, and it seems that imageX is not there anymore, so I've been using DISM, and it is SO SLOW to mount and unmount images. I see the following times with:

boot.wim

mount: ~ 2 minutes (not too bad)

unmount ~ 20 minutes

install.wim

mount ~ 5 minutes

unmount ~ 40 minutes (AND STILL WAITING!)

I've noticed that if I kill the process and reboot the server and try again it will unmount faster. Looking at resource manager, the server is basically sitting idle and not doing anything, so it's not like it's grinding the disks through the image file. Also, this install.wim image that I'm trying to unmount now, it seems to hang at the following:

C:\Documents and Settings\rmfadmin>"C:\Program Files\Windows AIK\Tools\Servicing

\Dism.exe" /unmount-wim /Mountdir:D:\mount /commit



Deployment Image Servicing and Management tool

Version: 6.1.7600.16385



Image File : D:\rmfisher\2008 R2\install.wim

Image Index : 1

Then, once it eventually starts showing a progress bar, it runs at an acceptable pace. So, something is causing it to hang when it's first starting this process. This happens with any .wim file I try to mount/unmount. ImageX worked so well!

These are the commands I'm using to mount and unmount:

"C:\Program Files\Windows AIK\Tools\Servicing\Dism.exe" /mount-wim /wimfile:"D:\rmfisher\2008 R2\install.wim" /index:1 /mountdir:d:\mount





"C:\Program Files\Windows AIK\Tools\Servicing\Dism.exe" /unmount-wim /Mountdir:D:\mount /commit

Any ideas would be great! Thanks!

EDIT:

Here is some more infor from the log file I have it generating during unmounting. I have it set at level 4. This is where the log sits when the process shows that it's just sitting at Image Index 1

Hi,

Have you tested it on another Windows Server 2008 R2 computer?

I am seeing the same behaviour with Dism.... I have been using imagex forever and find this a big step backward. The underlying disk doesn't seem to have a signicicant effect on performance.

I was seeing the same problem but it turned out to be the Antivirus application we were using (trend). I turned off the "officescan real-time scan" service and the problem went away. I used Process Monitor to give me clues. It seems that every time DISM made an OS call, officescan also made a call. This slows things down considerably.

Ive noticed this same behavior with SEP, so its not just a Trend issue. I bet McAfee has the same issue as well.

Hi all, thanks for all the replies. I suppose I should comment back that since I've posted this MS came out with a new version of AIK which I installed, and now the mounting is much faster. I think it's AIK version 3 now? Anyways, once I upgraded, mounting and unmounting are smoking, so I'm a lot happier. If anyone else is having these problems, hopefully you're on version 2 and you can upgrade to 3. It should help.

Thanks!

Can confirm that unloading Trend Officescan fixed this problem for me as well. Thanks!

Same thing here with Sophos Antivirus. Disabling On-Acces-Protection made dism start and showing the progress bar. Thanks for the tip.

Same thing with Symantec Endpoint Protection. After disabling with "smc.exe -stop" the progress bar showed and dism started working.
