Browsing thru folders very slow on network drives...

Hi,

I've encounter a very annoying problem:
Every time i change the folder, i get a wait time ... more images, more wait time.
Just around 30-40sec for 200 images with approx. 500KB.

This happen:
- a yellowish indicator appear, which maybe 'scans' thru the images
- a progress bar showing up the whole procedure

My XNViewMP Version: Version 0.93.1 64bits (Mar 6 2019)

And every time i change into a folder this happens, just also for visited folders.

This drive i operate is just a very slow network drive from my wireless router (~5MB/sec) and every unnecessary access slows down everything very strongly ... Where i can deactivate this 'stupid' behaviour?

And why in hell is this 'feature' still activated for network drives, why is this not automatic disabled for those drives?

PS: Sorry for my 'bad' english, i'm from Germany °°

+1. This is a huge nuisance even when we have locally a folder with many hundreds of files.
I don't know why XnView needs to read file header because the thumbnails appear fine and the images are OK even when the counter is stuck in 1%.

I encountered that even ACDsee v3.1 has such an option for disabling header reads, but nowadays it is quite darn old and doesn't work flawlessly under Windows 10, not even in compatibility mode :(

XnView needs to read header to update thumbnail labels for example
But during thumbnail process, you can't use XnView?

This header reading is indeed a background procedure but it slows down every image displaying while it's in progress, due (i guess) multiple readings on a very slow network drive.

Therefore this option should be disabled such to prevent this issue.

And nevertheless, it's annoying to see the yellow indicator marks running in every folder i switch every time and again and again....

PS: The problem is just more worse on a notebook ... the network drive i mentioned earlier is way slower over W-LAN with approx. 1MB/sec instead of 5MB/sec over LAN (i don't know why because the network drive is plugged into the wireless router which gives indeed all the LAN and W-LAN access at the same time)

But that is not in general the problem .... the problem is that still the old ACDSee Version runs fine with 1MB/sec but XNViewMP does not :!:

Well, I would be glad to see an upcoming version with an option as described.

Please make a note here when this version is ready. Thanks in advance.
