Slow to write tags to disk? - Page 2

kovidgoyal · 03-09-2025, 11:11 PM

you can exclude the calibre library folder from active scans, worth a shot. I doubt re-installing will have any effect, but it cant hurt to try. I would also suggest installing the current friday preview release as that has updated various dependencies which if this is antivirus related may help.

Well I did that. Installed the latest Friday release. Problem is no better. The edit page shows no signs of instant shutdown.

Big mystery, eh?

Small other thing I keep running into Maybe I should open a new thread: How to know the path of the current library? I typically have two libraries of the same name. One is a backup of the other. On the display all I see is library names and sometimes I trick myself and work on the backup instead of the original. Big blunder. All then get obliterated on next backup.
If I could see the path when I hover over the name I'd know.
And yes, I see, I know, I could/should take the trouble to change the name of the backup. But still.....

Tap 'O' after selecting a book. Explorer will show the Path.

As to the name. Right click the Library Icon: Rename

Thank you for that. Perfect.

If you don't want to change the names, give them different icons

Do you try Windows Safe mode.

I 'm curious as to what the concern is over the speed of tags being written to disk? The opf file is just a backup; the tags are actually stored in the database.

JSWolf · 03-11-2025, 01:54 PM

@abrogard do you have any computed columns?

See post #3

I update one at a time. ("edit metadata individually")

How slow? Press 'OK' and count: "One and Two and Three.............." generally get up to Eight or Nine.

And it's changes to any column… e.g. comments, not just tags. Attribution to disk i/o is OP's speculation.

Not sure if the OP has tried Windows Safe mode. As you would know, interference from third party software is a common cause of these sort of issues… AVs, access preventers protectors, search indexers, cloud syncers etc.

I'm still confused. How does he know that the DATABASE is not being updated in real time.

@abrogard has not said the database is not being updated, what he said is after making changes in MDE and clicking OK it takes several seconds before focus is returned to the Book list, at times even showing the unwelcome "program not responding" message. He expects it to be faster… so would I.

It's not unreasonable to speculate that behaviour such as this in a record keeping application, such as calibre, has something to do with writing of data, and for calibre that's a database and a collection of folders and files.

Is it a simple case that your drive is asleep and it has to spin up to write the changes?

I notice that when editing an ebook and clicking save. It take 10seconds or so before the save occurs, and I can hear the drive spinning up.

10 seconds? It's mostly instantaneous, rarely a couple of seconds here. Probably because everything is on a SSD?

Maybe a bit high, but I haven't ever timed it. I was just trying to imply it takes a few seconds to spin up and save.
The storage drive is a 5400rpm disk drive, so a bit slower but higher capacity than my NVMe M.2 c: drive.

Hi the thread. Sorry. I lost you for a while. To answer a couple of questions:

I have no computed columns nor any other 'fancy bits'
I have tried safe mode.
I have tried with plugins disabled (not system plugins, my added plugins)
It is not a sleeping drive. I could set it up with an edited text file ready to write and these tag edits ready to write. Every time the text file writes almost instantaneous, the tag writes on delay.
I'll a bit more as it occurs to me:
updates: win 10 is at latest update
calibre is at latest update
task manager: reports enough ram, cpu, disk space.
