Slow to open when device offline

Post by therube » 15 Feb 2020, 00:50

AllDup is Slow to open when a device (a folder) in the Folder list is offline.
More so when there are many such offline devices.

(On my slow computer), AllDup takes about 2 seconds to open.
With a single offline device, it takes about 10 seconds.
With multiple offline it may take 36 seconds or more.

During that time, there is no indication that AllDup has done anything.
(The AllDupPortable.exe process has started, but there is no window, no nothing.)

That is enough time for me to say, huh?
To look at Process Explorer, to see that AllDupPortable.exe is there, but that there is no associated Window.

XP (presently)
My NAS is off (presently)
NAS folders are using UNC paths, so like, \\NAS\offshore\hidefromIRS
(My network is presently in a state of KAOS, but I don't think that is the issue here, necessarily.)

Thinking you can try to duplicate this by pasting a dummy path, like above, \\NAS\offshore\hidefromIRS (only your hairdresser knows for sure) ;-), into the Folder list dialog.

Copy, \\NAS\offshore\hidefromIRS, to clipboard
AllDup -> Source Folders -> (context-menu) Paste folders from clipboard


Folder shows up.

Quit AllDup
Restart AllDup


AllDup is slow to start up, slow before it displays its' window.

Hmm... on a faster computer now, (not networked) Win7, following my steps above, can't really say I'm seeing an issue.

When I paste the path in, there is a momentary delay before it "checkmarks" itself.
But it appears that opening speed is not affected, or at least not in a noticeable way.

(On my slow XP, definitely noticeable.
I should probably disconnect from the network & test there again.)

AllDup just waits for a response from windows when accessing network ressources.
every windows version reacts different when trying to access a offline network ressource.
each windows version have different internal time-outs when waiting for a response from a network ressource.
i guess there are some registry tweaks to change the time-out delay...
