Visual Studio 2017 performance is slow if a complex page with numerous editors is saved on the Source view

created 7 years ago

[DevExpress Support Team: CLONED FROM T581690: Visual Studio 2017 performance is slow if a complex page with numerous editors is opened on the Design view]
Hi,

Actually, in VS2017, these problems occur even without the designer view. Have attached a video showing how long it takes to save an .ascx with DevExcpress controls in Source view when changing ONE character .

BTW, this is on a Quad Core (7700HQ) laptop with 32 GB och RAM and a Samsung 960 Pro SSD and performance plan set to High Performance.

(For those that can't see the attached video in SWF format, it takes about 30 seconds just to save the file).

Regards,
Patrik Johansson

    Hi,

    Please accept my apologies for the delayed reply.
    We researched this issue several years ago but didn't find a solution then. Currently, I initialized new research. Our R&D team has re-started research of this issue and now several our engineers are working on it.

    @Yusuf
    You mentioned that you 'wait tens of seconds for each change/click/save'. I reproduced the issue only when a file was being saved after the VS Designer was opened at least once.  Would you please send me a sample project where the issue occurs during other actions? Feel free to create a private ticket if you'd like.

      So, any news on this? Seems kind of pointless if DevExpress just pretends for year out and year in to do something about this when infact nothing is done as it seems. Please prove me wrong.

        BTW, just tried to edit 3 properties in a page with DevExpress controls, took about 4 minutes, of which 98% of the time where waiting for this problem. This is on a powerful XPS15 laptop with 32 GB of RAM and a fast Samsung 960 Pro SSD. We are close to giving up on this and have started to look into way of replacing the DevExpress controls with something from another vendor…

            I see, thank you for the clarification. Although we received several reports about the issue with design-time performance in Visual Studio 2017 and 2019, we couldn't reproduce it on our side. All our test samples (even with complex components on a page) work quickly. We asked the customers who reported this problem to share problematic projects, but didn't get any.
            If you have a suitable project, would you please send it to me for research? Also, please check how our sample that Helen attached to Visual Studio 2017 Designer performance is slow after upgrading to version 18.2 works on your side.

              Hi,

              After having upgraded to 19.2.3 this seem to be back to square one again with the Design view being unbelievable slow when trying to make changes in Visual Studio 2017 and 2019.
