Windows client uses a lot of ressources when waiting for sync [owncube]

I use Nextcloud 12.0.3 at (which I am quite happy with, by the way) and Windows Client 2.3.2 (build1). My processor is an i5@2.60 GHz with 4 GB RAM, running Windows 10 64 bit.

Sometimes the NC-client says that it is waiting for the next sync:

The waiting can last for 15 minutes or more and while waiting it uses about 30% of my cpu-time and noticeably slows down my computer.

This behavior occurs regularly, several times a day. As soon as the sync starts, the CPU-time goes down to about 2% and the computer starts running smoothly again. When the sync is done and the Client-Icon turns to green it’s 0%.

Here is the client-logfile (I was unable to get a server-logfile, though):

I don’t know whether it’s a problem of the client, the server or the user :-), nor what I should do for troubleshooting. Thanks for your help.

This was happening to me on my macbook wuth NC Hub 2, ver 24 i think.

I uninstalled the client completely, restarted and redownloaded and re-installed it. Works fine now.
