Slow single image open

Post by BixiSLO » Thu Aug 09, 2018 9:12 am

I have a folder on my HDD with 1384 items (most of them photos). I just ditched FastStone which is painstakingly slow...

After a few reviews I read, and fact I was already using XnView Portable I decided to give MP a go.
Compared to FastStone it's fast, but opening a single image takes seconds (!).
Portable version is blazing fast, but even default MS viewer is faster.

What is going on in the background?!
This is very annoying...

if you try to open a file from a folder (without others files), do you have same delay?

Same file in empty folder is faster, but my feeling is that XnPortable is still faster.
Here is a video: https://youtu.be/V8cXXNOWlIs

On the left the big folder - opened with MP.

On the right single file - opened with MP, Portable and MS Viwer.
MP is slowest of all...

yes XnView Classic is win32 based, XnView MP need to initialize all Qt's API. The problem is the startup...
Same file in empty folder is faster
really faster?

Yep. check the video... white screen is the lag between starting MP and showing the pic (vitage car)

It's interesting to now have an explanation for the frequently reported slow startup of XnView MP... :D

No solution in sight, other than future computers will be faster?

If you use XnView as a viewer, yes XnView Classic is faster to open
