XnviewMP starting very slow

[xnview]

i've sent you a PM

[xnview]

No, like I said above I'm using XnView MP on Windows 7 64bit.

It seems that the problem comes from QT librairies, i have contacted the support, i wait...

I am an enthusiastic Xnview user. I had Xnview installed and now I am trying XnviewMP. The program looks quite good, but there is one issue: the program is starting ver, very slow indeed. I double-click a very small image (jpg, 5 KB) and it will be displayed after ~7 seconds. The old Xnview was much faster. The same image was displayed by Xnview after 1 or 2 seconds.

Kind regards

Hey,

I know this is a really old thread.
But I got here by Googling my problem, which was the same. And I found out what happened.
So I figured I'd post a solution here so it's easy to find for others :

I regularly clear the thumbnail cache via the settings, but then, when I went to the folder where it was supposed to "not" be, it was still there and weighted like 1Gb.....
After I got rid of it manually, everything went back to normal.

I hope this helps someone.

FYI :
XnViewMP
Version 0.84 x64 (Jan 12 2017)
default path for your "Thumb.db" : %appdata%\XnViewMP

After 'cleaning catalog', the thumbnails was always cached?

I found a solution that makes Xnview start much faster. Go to:

- Tools > Options > System integration > Save options
- Choose «in registry» instead of «as INI in folder»

I know this is old but has been bugging me for a long time now and was searching for a solution, I can say before setting the INI to Registry I was waiting for about 5 seconds to open a picture in "normal mode" by double click on a file in a Windows Explorer Folder

After set the INI as Registry it finally got fixed and now any picture I open takes 1 second, as it usually should, and only was able to do if I had previously open a XnViewMP window already.

I tried doing this but nothing changes for me. But for me this issue is even worse. It takes a couple of minutes for XnviewMP to start. And I'm pretty sure it's not my pc. Xnview classic works just fine but I got used to the dark theme to much

Lastest version?

The first start of MP takes 3 seconds once a day since i use Win 11. After that it starts immediately. On Win 10 it was fine.

First start (after a reboot) can take some seconds even on Windows 10

I had the same issue, when first clicking on a image, there was a new delay of a few seconds before displaying it. this was a new phenomenon, normally it's pretty fast. So I browsed this forum for more information. I finally figured out what caused the delay so I wanted to share it here. I'm on Win 10 with XnViewMP version 1.0. A few days ago, I clicked on some linux distributions ISO files which were mounted as disk drives in Windows and it persisted after reboots, but I didn't notice it. So I right clicked on those pseudo drives and ejected them. Now clicking on an image display it instantaneously. Hope it helps someone.

with 0.99.7, you had no delay?

I didn't change version, it all happened during 1.0 over the last few days, once there was like 3 virtual mounted disk from ISO images, displaying an image got real slow, once I ejected these virtual mounted disks, it was fine again.

I tried the "registry instead of as INI in folder" change and the speedup was phenomenal. from like 10-15 seconds to less than 1. It also wiped my custom key for quick slideshow, but it's a small problem and a fair trade I then set it back to INI file again and it's still equally fast!
