Best Practices for performance during Client synchronization

Desktop

1

Steps to reproduce
1. ownCloud Desktop sync on Windows 2008 R2
2. A Big Folder called "Admin" with 35 directly subfolder, each subfolder with it own structure (subfolder and files...)
3. I want to know the best practices for configuring the client. What's the best way?

a) Add just the main folder "Admin" and let the client do the jobs, OR
b) Add each 38 subfolder as a folder connection?

Expected behaviour
I want to know the best option for performance

Actual behaviour
My first test, after everything Green (synchronised) I put a single file inside a sub/subfolder on the client and I have 3 minutes when using just option A (only one folder added) and I have 1 minute when using each subfolder... But I really want to hear about your experience.

I don't really know if there is much difference on the client side after all. But on the server you have quite some potential in optimizing your database settings and php-caching. I run some tests with previous OC versions (I probably should do that again with current versions):

Your result makes sense because currently the client will (on local change detection) traverse all the local files/folders and construct an in-memory sync tree from this.
If it only detects a change in 1 of your 38 configured sync folders, it only has to traverse/construct 1/38th of that amount (why it is still 1min vs 3min can be for other reasons)
