Hello,
Overall speed of IE 9.1.1 and 9.2.0 has gone down considerably. We can feel it as we have to work with large and very large images.
What we did was install IE 9.2.0 and do a clean build of our application.
After a clean build when we tested our application we observed that performance of IE has gone down to a crawl in many operations. Even standard operations like loading files with layers is also taking longer then it takes in older version.
I don't know if there are any setting that we have to adjust to get IE to perform at top speed (as it was in older version).
Please guide me here.
TIA

Hi Yogi
We did a lot of testing with 9.1.0 to improve the performance. Are you saying that between 9.1.0 and 9.1.1 you saw a performance drop?
Please send me a simple demo that shows this and I will do a speed comparison here.

Hello Nigel,
No. What I am saying is that I saw performance drop in 9.2.0 considerably not 9.1.1.
IE 9.1.1 is stable and performing at a blazing speed.
TIA

Hi Yogi
Can you give me some specific tasks/examples so I can try to reproduce here?

Hello Nigel,
I have not checked for a particular task or something but I have observed that by comparing our application compiled in IE 9.1.1 and the same compiled in 9.2.0.
For example just opening a file in application compiled in 9.1.1 and 9.2.0 showed that the application compiled using IE 9.2.0 took longer in loading the file and time to display.
We also got feedback from our loyal customers that the last update we released is slower then previous version.
Personally I also observed in the demo Layers_AllTypes that IE is taking longer to display the image on screen then it used to take in previous version. And if we load a 300 dpi multi layers file it's performance literally go down to a crawl when we are viewing the image at zoom 100% or more.
BTW our testing system is a 4th generation core i5 with 8 GB RAM.
I hope this information helps you.
TIA

Hello,
I forgot to mention that I have changed app demo Layers_AllTypes platform to 64Bit.
We generally avoid 32bit where possible
TIA

Hi Yogi
There is an issue with 9.2.0 and 64bit if the ielib64.dll is not found. Can you confirm that v5.4.0 version of the ielib64.dll exists in the exe folder?

Hi
I've done some tests comparing 9.1.1 and 9.2.0, and 32bit and 64bit, but could not find any appreciable difference (other than the DLL requirement above).

No it does not exist. In case of Layers_AllTypes demo I did not copy ielib64.dll to this demo folder.

Hello Nigel,
I've done some tests comparing 9.1.1 and 9.2.0, and 32bit and 64bit, but could not find any appreciable difference (other than the DLL requirement above).
Wasn't this DLL dependency for 64bit removed? Or am I making a mistake in my understanding?
TIA

Hi Yogi
The DLL is still recommended.
If the DLL is not found then ImageEn will try to make do with WIC. WIC mostly works with some small deprecations (lack of metadata being the main one).
Unfortunately, with 64bit apps, if the DLL could not be found, ImageEn would look for it *each* time an image was loaded, which can be very slow. This is fixed in the upcoming 9.2.1 (as well as global settings to switch between the Native/DLL/WIC engines.

Hello Nigel,
One more thing that I observed when experimenting with large multi layer images in the Layers_AllTypes demo is that if I remove the ImageEnLayerMView (Layer View) control, IE speeds up esp. it's responsiveness becomes better.
Has anyone observed this?
TIA
