I have 3 devices running Joplin, which synchronize to a Ubuntu-Server with WebDav.
Both my Windows PC, my Android Phone sync within 1-2 seconds, but for my Ubuntu-Desktop synchronisation takes about 8 minutes! (with a total of 25 notes, no changes).
The log does not show any errors, but it seem commands like ‘mkdir .lock’ takes app 2 minutes!
Also my scheduled sync is not working, the log shows:‘Recurrent sync operation DISABLED!!!’
Joplin 1.0.195 is built from source on Ubuntu 18.04 (Linux JetsonNano 4.9.140-tegra #1 SMP PREEMPT Mon Dec 9 22:47:42 PST 2019 aarch64 aarch64 aarch64 GNU/Linux).
