Der Overhead beim Transfer einer grossen Daten durch DB sollte vernachlässigbar sein (bei kleineren kann das anders sein). Ich würde erst mal mit den grossen Files anfangen - rechnerisch ergibt sich aus 1,3GB und 2:30 Min eine Transferrate von knapp 70 MBit/s, selbst wenn wir davon ausgehen dass der Transfer 2 Min dauert und die restlichen 30 sec für die Verarbeitung drauf gehen macht das immer noch 86MBit/s und bei 1:30 über WebDAV 115MBit/s - das ist in etwa Fast Ethernet - aus diesen Daten würde ich den Flaschenhals erst mal im Netzwerk suchen - kontrolliere bitte ob du irgendwo eine Limitation hast - gewollt oder nicht. Wenn die grossen Dateien schnell genug laufen kann man bei den kleinen weiter suchen und Datenbank, Webserver usw analysieren. Es gibt ein Paar Apps die die Sync Performance beeinflussen: - Collabora CODE app - External Storage app schaue ob diese aktiv sind und deaktiviere sie testweise.

I was unable to complete initial full sync of the client during 3 days for ~30GB data/70k files. After lot of wrong assumptions I was able to isolate the official “external storage” app with 3 mounted SMB shares to be the issue. the shares itself a not replicated. disabling the app immediately made the replication running fast.

First some Server-Specs: Model: HP Microserver Gen8 (Intel Celeron CPU) OS: VMware ESXi 6.0.0 (Virtual Maschine: NAS4Free) The Datatransfer via a CIFS/SMB -Share is very fast (80-100 MB/s), but the synchronisation between Nextcloud and the PC is very slow (10 KB/s to max. 2 MB/s). I access Nextcloud in the local network. In addition, the CPU utilization is very high (40-90%). Is that “normal” or where/what is the “mistake”?

When deploying containers (with this guide [https://hub.docker.com/\_/nextcloud/](https://hub.docker.com/_/nextcloud/)) everything is fine and my desktop sync client can connect, but for some reason the upload speed is limited to 30MB/s. Using my “traditional” installation directly on debian this issue is not present, I can sync files maxing out my gigabit connection (110MB/s upload speed).
