Worth installing for a folder with 10k files?

Friend bought himself a WDTV Live and since I use Serviio with my Samsung C650 and it works great with that(only have like 100 files tops) I thought maybe he'd like it do. Now he dumps all of his movies and audio files into one folder on 2 pc's. One folder contains 10,000 some files and the other 8,000.

I set up Serviio to scan the folders and by the time they both got to 4000 something they started to slow down. Left his place and would check later via Teamviewer.

For such a large number of files in a folder should I even be using Serviio? I'm wondering if and when its finished what would happen when it checks for new files and how long that would take too.

Or - for those that know the WDTV Live - should I just share the folders over the windows network and not worry about Serviio?

TIA

Why can't you split the folder up? 10k files in one folder is just plain wrong imo

The slowing down might be due to the client - depending how it asks for data. Also, some renderers (like Samsung) have a limit of files to show via DLNA in one folder. So generally I'd suggest you split it in some subfolders
