Hi there
I have human observable but less than 3 seconds lag when, for example, entering a mundane folder which contains only 3 sub-folders and total size is pretty sane.
I've read posts like this and this , also did some Windows and DO config tuning but still have the lag issue.
This is Windows 11 on a new computer (AMD 9950X with 64G RAM), OS freshly installed ~3 weeks ago. DO and many programs were installed in the past weeks.
The lag happens in some but not all folders on my disk. It's no more then 3 seconds but still human observable, at the same time mouse pointer changes to sand-glass which demonstrates probably some processing is ongoing (details in my dump files via email).
I've followed Leo's guide here to create:
5 memory dumps (7zip compressed)
slow-dump-OpusConfig.ocb : my DO config in case this is useful
slowRecording.mp4: screenshot video, shows how/when the lag happens
I've sent to crashdumps@gpsoft.com.au with above info. Can you help look into this? Of course please let me know if any more information is needed. Thanks.
Were the memory dumps made while the delay was happening? The delay seems too short to be able to make a dump in time, so if they're from before or after the delay occurs instead they probably won't tell us much.
How fast does the same folder open in other programs?
Are there any hidden items in the folder? (The status bar should tell you if there are.)
The memory dump is ... tricky, I made them like this:
. stay at parent folder
. switch to Task Manager and select DO then generate memory dump
. switch back to DO and enter the sub-folder, short lag observed.
I agree the timing/duration may not be sufficient for the mem dump. Any other kind of dump that's useful? or other way to generate one? I'm happy to follow your way.
Entering same subfolder in Windows Explorer is fast, no lag and mouse pointer doesn't change to transitory sand-glass. I put DO and Windows Explorer side by side to perform the test, did a couple of times, Windows Explorer seems fine.
The parent folder has only 3 subfodler and no any hidden files. Status bar confirms this.
Say there is lag symptom entering folder X. Once I'm in inside folder X,
Going up using any of these, short lag is guarantee when re-entering X:
. clicking the mouse side button (5 button mouse)
. Alt + UP shortcut. I customized this to be up a level (so same shortcut as Windows Explorer)
. double click the blank area
. Backspace to go back, effectively go up in my case
However if I go up by clicking the '..', or clicking the parent folder in location bar, there is no lag.
well no... either of these has delay:
. mouse side button to go back -> no customization done, it just works in DO and Windows Explorer and any web browser. I think Windows just supports this
. Alt + UP: by default this is collapse folder in DO, I changed Alt+UP to be 'Up a level'
. double click the blank area: I think I customized this? or this is DO default, cannot recall
. Backspace to go back, this is DO default shortcut IIRC.
I think it must be something external to Opus in that case. Maybe antivirus? That could also down access to directories in one program while they're normal in another, perhaps.
I'm on Windows 11, besides Windows default security software, I didn't install any 3rd party anti-virus, computer cleanup or management (whatever you call it) software.
Only thing is, why there is no lag by clicking the '..', or clicking the parent folder in location bar?
Is it possible that you have some debug-build version to let me run to capture some log or dump? I'm happy to accommodate.
Microsoft's antivirus is one of the worst ones these days, in terms of negatively affecting software/performance. Although it may not be the cause in this case, of course.
If you want to diagnose it, using Process Monitor to see what's being queried and if any of the actions is taking unusually long is the best next step.
Yes, that is strange and makes me suspect something weird is going on with the machine. E.g. I've seen weird pauses like that with a new motherboard with immature BIOS/drivers that didn't handle switching power states correctly and kept going into a low-power mode for too long, making the desktop randomly pause for a second. (In that case it affected Chrome rather than Opus, but the same kind of thing could affect anything, and whether it was triggered or not depended on a lot of small factors like how much the mouse was moving or what it was moving over just before doing something else.)
I have tested DOpus 12 before, and in the same columns, DOpus was relatively slow, and so were the test results of others, so antivirus software was ruled out. DOpus 13 seems to have made some improvements.
What was slow? Which columns? What relevance does old experience with Opus 12 have on a thread about Opus 13? I'm not sure this information helps anyone.
