Re: [QGIS-Developer] sudden performance issues with my QGIS installation

[Catania, Luke A ERDC-RDE-GRL-VA CIV]

I had an issue with slow down and somehow my QGIS ini file has grown very 
large.  I created a new profile and that fixed the issue.  I don't know what 
caused the ini file to grown in size.

I had the OneDrive connected in the browser. This was making it impossible to 
work with QGIS. After removing it things went back to normal.

I followed Richard Duivenvoorde's suggestion to "Hide from Browser" option (see 
[0]), with the following exception: one of the network drives was not even 
visible in the Browser Panel to right-click on, but it was being "scanned" by 
QGIS. I had to open QGIS3.ini and manually add it as a value to the key 
[browser]/hiddenPaths=. Now, I can use the Browser panel without QGIS freezing 
for 30 seconds every 2 minutes!

IMO this is not an option, the only option I see is to fix the slow
loading times and possibly move the directory scan for non-local
folders to a separate thread in case it is not yet the case.

Fyi the browser tree is not only used in the browser panel but also in
the data source select dialog and in other places too.

Kind regards

I think it would better spent looking into why and fixing that and not just
bidding it and removing quite good feature we want people to use if we
can.  The browser is quite powerful and bidding it by default would be a
bit of a shame.

Suspect we might just have to get creative with how to handle the file
loading, they should already be done in background threads but maybe
something more is needed

Re: [QGIS-Developer] sudden performance issues with my QGIS installation

[Jeff McKenna]

Hi Andreas,

As a user, I wonder (out loud) if the Browser Panel should be hidden by 
default, in future QGIS versions.  This would avoid this common issue of 
slowing down QGIS for new users, and give the new user a guaranteed 
positive QIGS first-use experience.  Has there been any discussion on 
this possibility?  I was surprised to read here that it is the opposite 
case, where devs are promoting use of the browser panel more and more.


I just thought that I'd share my longtime-user opinion, and hopefully 
not sound too negative.  I just feel disabling the browser panel by 
default would prevent so many issues for new users (and the advanced 
users can turn it on for their use when they need it).  So, benefit the 
new users, and cause the devs an extra button click to enable :)


Related: when I give QGIS training, it is the first thing I instruct, to 
close the browser panel as it causes network issues often.


thanks,

-jeff

Now it would be interesting to find out, what, in the browser in your

This is kind of problematic, as the QGIS devs are more and more

know if it is so wise to promote the browser so much. Or at least we

Hi Dimitris,

It is not the first time I hear that the Browser Panel is slowing down
QGIS too much (even bringing it to a halt almost). 


Now it would be interesting to find out, what, in the browser in your

This is kind of problematic, as the QGIS devs are more and more

Just a shot in the dark: does it help if you close the "Browser" panel. 
Sometimes the browser (esp. with network drives) can slow down QGIS

[QGIS-Developer] sudden performance issues with my QGIS installation

Hello all,

I am facing some performance issues lately with QGIS. I have been using
QGIS3.14 since the last six months (Windows 10) without any problems. It
was always very fast in any type of analysis. Suddenly it stopped
responding. Sometimes it lags for a minute or more while performing simply
tasks (load layer, save layer as geojson etc.).
I have tried to uninstall, delete the registry and the plugins and
reinstall it but the issues perform. I have tried the newer version (3.16)
and the older one (3.10) but I still get the same performance issues. I
have also trired to run it with a new profile and without any plugins. When
running it with no plugins it launches faster but then I get the same lag
issues when loading layers or running simply analysis (buffer)

Do you have any idea what could be causing this? I was wondering if some
other software that I have installed recently could have created an issue.
