this is after the april set of windows updates that I've just noticed a whole bunch of slowness coming from the the ide.

a simple cut and paste of text will take 10 seconds. the screen seems to be refreshing/drawing really slowly for some reason.

i've seen an earlier post about slowness in the ide and I've already tried eg: removing sophos antivirus. disabling windows defender, adding exclusions to windows defender, removing .net framework etc.

 

I'm going to try to reinstall the ide . i'm just wondering if anyone else has encounter this issue.

 

latest windows 10 1803 build 17134.153

 also .net 4.80 

 

 

Can not login nor logout

hi all. seems like if the hyper V role is on, its very slow. i just uninstalled the hyper v role on my windows 10 computer and the speed is dramatically improved (ie: almost feels normal)

Hi Chris;

I have "Hyper V" turned on on my development & test PC's but with *no* speed degradation issues with PowerServer or PowerBuilder. However, I am using superior AMD processors ... LOL! OK, just joking but ... you may need a BIOS update. ;-)

Regards ... Chris

I'm also wondering if its windows 10 exploit protection. i've added in the pb ide executable as a an exception to all exploit protection settings. seems a little faster.

I suspect it may be related

 

i removed the manually installed intel graphics driver and installed the ones from microsoft update and it seems better (ie: intolerably slow but not incapacitatively slow ) .

If you have a DataWIndow object with a bunch of function objects called by expressions and these functions are making in-line SQL calls, that can be very slow and is not recommended.

actually it looks more to be like slow screen redraw or background redraw that is happening.

 

for eg: this window has 97 objects (command buttons, single line edits, datawindows).

 

doing a control+A to select all objects see a very slow selection.

opening this window also shows slow redraw as each command button is displayed.

I also notice the slowest ones to render/draw on screen (it doesn't follow tab order) is those with powerscript statements that access the database (eg: update table , alter table)

i tried the powerbuilder 2019 build 2002 and its also the same behaviour

Hi Chris;

I have only encountered something like this twice in my 30+ years of PB. One cause was traced down to the video card and the second to the video driver. Replacing the video card / driver did the trick.

Food for thought

I'm thinking it has something to do with how you have Git set up. You would think it would be fast since the IDE is connected to a local repository. Perhaps the location of the repository isn't ideal.

Hi Chris;

  FWIW: PB 2017R3 MR01 (build 1880) IDE super fast on my W10 PC's. However, I am using a newer release of MS-Windows ...   Windows 10 Version 1809  build 177763  (with Windows Defender).

HTH

Regards ... Chris

yes. i had git as source control. database is sql server 2016 

 

I've reinstalled powerbuilder. git is not setup yet. there is no slowness at the moment.


I take it you suspect git is the issue. I will not setup the source control yet then

What do you have for source control or database connections while this is happening?
