Hello Guy! :slight_smile:
Did you plan the multi file sync? Because when we have to upload 8000 files of 12kb each for example, it's very very slow (2-3hours) whereas it's only 30mb 
.
May the force be with you!
We looked strongly into it, ownCloud Desktop Client 2.3 will again have some improvements. Going forward we are looking into http/2 versus bundling, etc.
Huge numbers of small files continue to be on top of our mind.

In case somebody is interested in the research behind it ...
Okay, thank you for your fast answer! 
Database tuning and filecache locking via redis should help a lot:
