[SOLVED]Dolphin: Safely Removing Device after Large Copies - Very Slow

Whenever I mount my external storage device to my PC and copy large files (over 3-4gb usually), Dolphin starts behaving in an unusual way: There is a noticeable delay in unmounting physical hardware from the machine that results in a sluggish behavior. On the right side panel of the application, I can see the wheel spinning, indicating that the device is in the process or being unmounted, but the process has been observed taking over 30-48 seconds in doing so, sometimes even by a minute.

I've launched Dolphin from the CLI and read the output but I couldn't really find anything abnormal.

Can anyone who knows anything about KDE's Dolphin tell me what's going on during this umounting process whenever I 'safely remove' the device? Why could it take this long to unmount something?

Because it has to flush 3-4GB of data to the device.  Why is it surprising that that could take 30 seconds?

Re: [SOLVED]Dolphin: Safely Removing Device after Large Copies - Very Slow

That's interesting. So it has something to do with flushing data...

Still being relatively new to Linux and its mechanisms, (it doesn't do this syncing behavior on Windows , or I've never seen the delay, but obviously that's another OS with different workings), I would like to find out more about how this works.

You are quite insightful, do you have any documentation I could follow so that I could read more about this process?

There're two links in that thread and a further link in the linked wiki. Start w/ that.
