Same thumbnail cache for different users

Post by xxnner » Fri Feb 07, 2014 9:14 am

Good morning,

regarding the thumbnail cache there are three options to store it:
- user's home directory
- XNview
- Custom

Is simultaneous using of same cache possible from different network users?

User1 opens a directory C:\Test, at same time User2 opens C:\Test
=> Possibel without any issue?

Thanks, best regards!

I think that it's possible. Thumbnails are already in cache db?

Thumbnails are in cache, but sometimes new files are added. So it is possible that two users simultaneously access the thumbnail cache db while updating the new thumbs.
How will xnview.db act with this simultaneously access?

Thanks, best regards!

This was recently discussed in the MP forum.
There are lots of potential pitfalls, but this perhaps applies moreso to MP, because there is so much more stored in databases in MP.

The basic problem is that C:\test is not the same as C:\test on two different machines.

So you need to make sure the same image files are mapped to the same path.

The question is "what is the benefit of sharing the cache"? There are certainly potential problems doing it.

Benefit of using same thumbnail cache is speeding up the first search (for example on terminal servers), saving disk space especially with large picture collections and central administration. Mapping to same directory/file is ensured.
