SkieHow long does a Skie sync take?
Skie does not publish a sync time, because it depends on the network, the device and how much has changed. For a device on working Wi-Fi it is a short background task that users rarely notice. The unlock gate only appears when the last sync is stale, and it only blocks if the sync cannot finish.
A sync has several parts: connect, fetch the current signed rules if anything changed, apply them, read each protection back and report. A device that is already up to date has little to fetch. A device returning from a long absence may have more to apply, though the rules themselves are compact.
What changes the duration: signal strength, how busy the school or office network is, how many devices are syncing at once, and the speed of the device. We deliberately do not quote seconds, because a figure measured in one building would mislead in another.
What you will notice in practice is mostly the absence of any wait. Syncs run in the background, triggered by the interval, by internet returning, or by the screen turning on when the last sync is old. Only when the last sync is past the Due limit does the unlock gate show, and then it clears as soon as the sync finishes.
If syncs feel slow across a whole site, test the network. The network check wizard exists for school networks and can show whether the filtering DNS and other needed paths are reachable. Slowness on one device points to its signal, battery or storage instead.
If you want to see it happen, use the sync action on a device page and watch the last-seen time. Do the same on several devices in one room to compare.
Practical tip: avoid starting a bulk action on an entire campus at the moment lessons begin. Start it early, when the network is quiet.
