As a Krusader fan I can say that the issue is not limited to just Dolphin, and
I don't think the issue is with mounting as an already mounted share becoming
unresponsive is also causing such issues.

It's likely to be a matter of either both Dolphin and Krusader trying to get
info on mounts in the background for something like disk usage measurement, or
KIO is serving too much information somewhere, poking all mounts even when not
desired.

Unlikely to be common at least on the local network. My rather weak server
sharing a slow HDD is not affected in normal circumstances, it only gets slow
when I'm well aware I'm abusing it with I/O. Other than that I use the SFTP KIO
slave for high latency targets which is surely slow, but by not being a mount
it doesn't exhibit this issue.

The issue possibly got better over time with the addition of some timeout, or I
just happened to be "lucky" because the share wasn't in use so the symptoms
weren't severe last time I've seen it. It would be interesting to confirm
though whether my Krusader usage mattered there and Dolphin still freezes.
Although I haven't used Dolphin last time, confirming the issue because it's a
known problem, and I happened to "enjoy" waiting for timeouts quite recently
with Krusader as I  was messing with the network making the mounted NFS share's
server unavailable.
