Hi, i have switched 3 iMac in my work office to Arch Linux with Plasma 5.9.4 Qt 5.8.0 kernel 4.10-6-1-ARCH. All is working but i need to sorve some problem: I'm using korganizer to sync our business appointment with 4 calendars (one for each worker). My Server is ownCloud 8.0.2 loaded into a virtualmachine based on Ubuntu 12.04 and installed in my local network.

The main problem is the excessive sync time for korganizer (is same in each iMac) to download new events loaded into the server from any device like smartphone or from same koranizer on another iMac. For exemple, if i create a new event from my smartphone or from korganizer on any iMac, korganizer on other machine need about 20 minites to download the event. Otherwise all smartphone need about 1 minute to download event.
I've made a test: i've created a gmail calendar on Korganizer, all work fast. Any events created from web page of gmail calendar is downloaded immediately on korganizer pressing button to sync calendar.

Instead on owncloud, korganider need about 20 min to download any events although pressing (or not) button to sync calendar. Obviously i've setted the sync time of any calendar in korganizer to 1 min. (minimun value)
Otherwise any upload for korganider into the server are immediate.

My secratary need a fast sync but i don't wont use gmail calendar. I would like to solve this issue with owncloud.

What i can do? Are any setting from ownCloud to be changed maybe?

Thank's.
