currently my wife and me, we are running DEVONthink database on several devices:
- macOS: Mac mini, MacBook Pro
- iOS: 2x iPad Pro, 2x iPhone 7
There 5 database to be synced.
Finder reports file size from 370MB thru 38GB.
For the biggest database DT reports:
20.000 items total, about 14.000 PDFs and 900.000 words
We are using iCloud sync.
My Internet speed is 50MB up link and 10MB down link.
It works very well and fast on the macOS devices.
On the iOS it is unbearable, it takes forever to complete syncing on the iOS devices.
For syncing the iOS device is plugged into the charger, the screen is dimmed down and the device ist running DEVONthink To Go as active task overnight. So DDTG is not interrupted or powered down.
On the iPad it takes several hours and on the iPhone it takes longer than overnight.
I am not talking about the initial sync which took several days. I am referring to small and medium changes in the database.
Is this normal?
Is there something wrong with my local network?
Or is the horsepower (processor and memory) the main issue?
Further information – I observe always two steps:
- downloading data from iCloud (long time, but acceptable)
- syncing versus iCloud (very slow progress, unacceptable)
