Dreamweaver CS5 100% CPU when opened.

[shieatt]

I have just installed the Adobe Master Suite on my work PC and the one program I need the most (Dreamweaver) hangs at 100% at all times after opening.  ALL other Adobe CS5 programs DON'T do this, and remain at a low 0-20% during idle. 

This just started happening about a a day ago, and before that was performing normally.  I have also just installed new memory (3gb) and figured it must due to faulty memory.  Yet I replaced my sticks with the old ones and still the problem continues, while all other programs work fine.

I'm assuming it's either some memory leak or virus or ... who the heck knows, but I tried re-installing the program again and booting into safe mode but both to no avail.  I also deleted the personal config file, but this also did nothing.  Also, this was not doing this before hand but only happened a day ago.  I literally have no idea what I could have done but I know for sure that my PC can run this program as I've already designed an entire site with this version. 

Are there any programs I can use to figure out the culprit or find out what is wrong with Dreamweaver.exe?

Hello folks,

Sorry for the frustration you are experiencing with Dreamweaver.

Please try the solution in this document and let us know if it helps:

Hi Carey,

While your solution is great for fixing DWs hang time when opening certain documents, it did not help the CPU hit that CS5 has on computers when documents are open.

I have two screenshots showing how DW affects my CPU. See below:

Screenshot 1: http://www.webmagi.com/DW-CS5-CPU-Issue/DW-Files-Open.jpg

Screenshot 2: http://www.webmagi.com/DW-CS5-CPU-Issue/DW-Files-Closed.jpg

In Screenshot 1, I have two documents open, an HTM file, and  PHP file. Dreamweaver is slamming one of my cores.

In Screenshot 2, I have closed all files, and the problem goes away.

Should this be reported as a BUG?

[Web Magi]

I just submitted a bug report for this issue. Maybe if enough reports are sent, Adobe will fix this issue.

This does not help, nothing does. Please fix this bug!

I experience this too on a Win 7 x64 machine running Dreamweaver CS5 11.0 build 4964 (Dreamweaver uses 1/4 of my quad-core processor). However, it only occurs WHEN I HAVE AN .XML FILE OPEN. As soon as I close the .xml file, the processer returns to normal.

I implemented the quick registry change shown in the previous post (http://kb2.adobe.com/cps/887/cpsid_88742.html), and it seems to have fixed it based on my cursory testing.

Hope this helps!

DW CS5 build 4964, Win7 x64 Core2 Duo, 6GBs, and DW still eats up 1 full core just sitting there, from time to time. I -THINK- that I had tested this issue and ruled out xml as a triggering file type to cause this issue. I mostly edit .XML and .CFM files so it is possible that it is an XML file issue, but I think that it was happening with CFM files only.

I will watch this and if I see a CPU spike, I will close my XML and see if it drops down. I know -FOR SURE- that I was able to close out CFM files and reduce the processor load (almost file per file the CPU would drop down).

I have implemented the recommended change (http://kb2.adobe.com/cps/887/cpsid_88742.html) and I will keep an eye on the CPU usage.

Did anyone else have this problem on CS5, upgrade to CS5.5 and have it get worse?

[epic_Shimmer15A9]

Well, this is not a fix, but it does solve the 100% Core consumption... I have found that if I toggle "Live View" on and off, the Core consumption drops to near 0%... And stays at that level... I can repeat the solution on every page that opens and pushes my core up to near 100%... Click on "Live View' and I see and instant drop in core consumption... All is good after that... Hope that Helps... Adobe, why is the software doing this?

[Guest]

I get the same problem in 5.5, and your fix worked. I see that Adobe does not reply.

[onetrev2010]

I can confidently say that one cause of CPU usage spike from opening Dreamweaver is from Site-Specific Code Hinting. I have a Core i5, Windows 7 64bit, and only one WordPress site with code-hinting enable, my CPU usage spikes around 70% and holds there for up to minute upon loading Dreamweaver.

If I delete the site specific code hinting config file, then Dreamweaver acts normally and has normal CPU usage upon loading. This CPU usage seems pretty extreme. I hope this is some sort of error rather than normal behaviour but I have my doubts. Can anyone else confirm this happens on their system?

[Axertion-yOFSKR]

Hi all,

I'm having the same problems here.  I've noticed over time that Dreamweaver has taken increasingly longer to boot. 

I opened up my Resource Monitor to see what exactly was bottlenecking with Dreamweaver.  It appears at a glance that Dreamweaver does some intensive file-writing which maxes out the CPU and the hard-drive...causing the entire system to lock up.

When booting Dreamweaver, I noticed the most intensive read/writing was occuring in: C:\Program Files (x86)\Common Files\Adobe\Adobe PCD\cache

I also noticed a one-time occurence of Dreamweaver reading all the files in my site.  I'm using since I have the "Files" pane opened, it was reading that folder and caching all the files/folders into a cache (as I tried to reproduce Dreamweaver to read those files again, I could not)

As of now, Dreamweaver CS5 opened without any files or projects open runs at 164,000 K which is massive for an idling program!

I've done a few things though that seems to resolve most of my Dreamweaver startup issues.

1) Followed step 4 here: http://kb2.adobe.com/cps/405/kb405604.html (deleted the cache file)

2) Followed Adobe's advice and added this registry edit: http://kb2.adobe.com/cps/887/cpsid_88742.html

3) Reset my DW panels to a default view.  I closed ALL panels first, exited Dreamweaver....rebooted Dreamweaver several times...then set the panels back to "Coder Plus"

I really hope Adobe addresses these issues with a patch of some sort.  I use several other Adobe programs and don't experience the drastic hanging and resource hogging that Dreamweaver diplays.  All Adobe programs take up quite a bit of memory, but for some reason Dreamweaver is the only one that locks up during it's startup.

Also, here are my specs if an Adobe engineer needs them.  Adobe employees can contact me if they want any further information related to my experiences with this issue:

Intel(R) Core(TM)2 Duo CPU E8500 @ 3.16GHz

4.00 GB RAM

Intel 510 120GB SSD

ATI Radeon HD 4670

Windows 7 Ultimate 64bit

I am running a Quad Core Q6600, 4GB ram, just installed the trail for Dreamweaver CS6 and I still get 25% CPU Usage

Any solutions to this? Tried clearing cache, tried unticking "enable related files" and a few others things but still no luck! Even with the LATEST CS6 version!!!

[nan7ee]

Dreamweaver CS6 Trial still 50%+ CPU !!, I don't want to buy it.

[John Waller]

That's the DW CS6 Beta.

There is no CS6 Trial available until after CS6 ships next week.

[shdskj_gfd]

I too have the issue with CS6 trial.

@shdskj__gfd,

As this topic began in 2010 re: CS5, you might want to look at newer discussions re: CS6.

[mactavish2191]

Nancy O this doesn't solve the problem either yet Adobe Dw CS6 still spikes my one out of four core to 80 to 100% .

I have done all prefrence deleting ,cache cleaning, registry editing which are posted in this forum but all these have no impact to Dreamwever.

I don't know why Adobe just release a patch and fix this issue because people buy these products so the "Company" should have a responsibility to fix these issues.

[Preran · Accepted solution]

The 100% CPU issue has been fixed in Dreamweaver CS6 update 12.1 for creative cloud subscribers and 12.0.3 for non-subscribers.

[jclarx]

Sorry, but this is not fixed in my experience. I have version 12.0.3.5861 (fully updated as of today), and Dreamweaver is taking 100% CPU - not just at startup, but much of the time. I am having to fully force quit and restart Dreamweaver and my Mac many times each week (often multiple times/day).

I'll look for answers in other threads.

Thanks.

[skingsford]

I gave up on Dreamweaver after trying many times to resolve this problem, searching forums etc.
Found the update of this post and got my hopes up. Hoped the update (12.0.3) would fix the problem.
Been trying for two days to update Dreamweaver CS6 via Adobe Application Manager.
All I see is: "The update server is not responding. The server might be offline temporarily, or the Internet or firewall settings may be incorrect."  Even with the anti-virus and firewall turned off.

[Preran]

Hi all,

As mentioned in my earlier post, this issue was fixed with Dreamweaver update 12.1 and 12.0.3 (for perpetual license holders). I am not sure if you can update trial versions, but just in case you can, the updaters are here http://www.adobe.com/support/dreamweaver/downloads_updaters.html

[dervinzzz]

I am using Creative Cloud, Dreamweaver CS6, Version 12.2 Build 6006.

Dw uses ~50% of CPU when on idle, so it seems to me that the problem has not ben solved properly.

This is a rather annoying bug, because it slows down the whole system (quadcore, 8gb, win7 64bit) what makes working a pain...

[Kindhearted_kindness16B6]

I solved that issue for Dreamweaver CS5!

Somehow the main window message handler of the consumes very much CPU power. In detail the mfc90u.dll!#6019 part that uses USER32.PeekMessageW.

Here is the patch:

https://forums.digitalpoint.com/attachments/dreamweaver-cs5-cpu-fix-v2-zip.54851

(Original Post:

https://forums.digitalpoint.com/threads/dreamweaver-cpu-usage-high.498651/page-2#post-14860313

)

I guess things in DW CS6 are still the same.

Well to get this patch applied the first issue will be to find the right mfc90u.dll inside the windows side-by-side mess

c:\Windows\winsxs\

• Run DW CS6;http://processhacker.sourceforge.net/ Search via ctrl+f for 'mfc90u' might do that trick

Next issue might be to fight for ya right to write.

• mfc90u.dll might be in use by DW or other applications(processhacker may help ya here again to find open handles to mfc90u and close them; or kill the process)

• Maybe you've not have enough access rights to write to files that are in the Windows\ folder. As admin you might need to take over ownership before you can garnt you full access to the folder(and files) mfc90u.dll is in. Right click on the folder and choose propertiers/security to set that kind of things.

Important: Please give some feedback if you got this also working for CS6.

... and the path to mfc90u.dll for CS6 like for example:

c:\WINDOWS\WinSxS\x86_Microsoft.VC90.MFC_1fc8b3b9a1e18e3b_9.0.30729.4137_x-ww_a57b1f13\mfc90u.dll
