Calibre takes a long time to open

I reinstalled 3.17. Has the same problem. Installed 3.18. Same problem. So I am back on 3.16.

3.16 does take longer to load that I remember, but not nearly as long as 3.17 or 3.18. It's probably something with Windows 10. Not my favorite 'service.'

Once any version is finally loaded everything is fine. Linux is starting to look better every day.

Try temporarily disabling your antivirus and seeing if it makes a difference (disconnect from the internet first).

No change!

Try overriding what Temp directory Calibre is using via the Environment variable CALIBRE_TEMP_DIR.

Https://manual.calibre-ebook.com/customize.html#id1

The purpose of the above would be to ensure that any aggressive file cleaner that you run automatically is not deleting newly created Calibre temporary files.

Calibre Version 3.17 had the change "Store temporary files used by the editor and viewer in the cache directory to try to prevent errors caused by 'file cleaner' programs deleting temporary files still in use", but you have not mentioned either the editor or the viewer.

You also have not indicated whether or not you are running as an Administrator or User.

Hmm I have to say I'm stumped...

[JSWolf]

I've not seen Calibre 3.17 take longer to load than 3.16.

I'm using Windows 10 Home 64-bit on my laptop with 8GB of ram. I'm using Calibre 64-bit.

What is your setup that's acting up?

[DaltonST]

You debug log is abnormal in that if were not manually edited by you personally prior to posting, it appears that Calibre began to start, and then started over from the beginning. See the extract of your log below. However, if you did redact it, you really need to attach the original debug log from a single execution of Calibre with debug turned on.

↑ ↑ ↑ - yeah I noticed that too. I wondered if it was something to do with autostarting the Version 3.x server, which is something I don't do.


@K8HW - Did you try DaltonST's suggestions in post#19,

Your problem has the hallmarks of a 3rd party program 'intervening', if you haven't already done so, try one or both of these techniques to isolate the culprit:

• use Task Manager to disable all Start-up Tasks and then run calibre 3.18,
• run calibre 3.18 under Windows in Safe Mode.

First of all I want to thank all of you for your assistance. I couldn't figure out how to play with the temp variable. I couldn't even to figure out how to start up in safe mode!

Apparently the problem is Windows 10. (big surprise)

The log file was NOT edited. I have included a recent log file. It shows the same stuff.

Now I have a ridiculous observation. Calibre starts every time in under 3 seconds if I have the Windows 10 stopwatch running in order to time Calibre. Makes absolutely no sense. If I don't have the stop watch running Calibre takes close to three minutes to start.

~Dave

EDIT. I have included the startup log (BAD Calibre log,txt) for when Calibre takes 87 seconds to start up. Look nearly identical to me!

Do you have the splash screen enabled and does it make a difference if you disable it in Preferences->Look & feel

[BetterRed]

I did some tests - following is what is logged if I use Preferences->Restart in debug mode.

Interestingly, there's some debug printf's from GetFileName in the first 'start', but not in the second.

And this is what I get if I run "calibre-debug -g 1 >> calibrelog.txt 2>&1" from a command line.

I've not noticed the 'stuttering start' being logged before, but I rarely start in debug mode, from the command line or via Shift+Ctrl+R. When I first saw the OPs log I thought -- that looks a bit odd, but I shrugged and moved on.

Turning the splash screen on increased start times from 2.xx secs to 5.xx secs.

---

Yes I'm still using 3.16, I'm awaiting for any further developments re Split Book List and View Manager, I use an old version of View Manager and I haven't had time to see how it interacts with Split List.

[kovidgoyal]

The double startup output in the gui debug log is normal, it's an artifact of how debug restarts work.

[kovidgoyal]

I've also added some more debug prints to the startup code, which should give us some more info on what exactly is taking so much time. If I had to guess, I'd guess it is that the startup uses a 1 millisecond single-shot timer to proceed with initialization, I suspect for some reason that timer is hanging on K8HW's system, this would explain why it doesn't happen when running the windows stopclock.

Here is how to start Windows 10 in safe mode.

I disabled the splash screen and Calibre's startup is back to normal. A big improvement. I wonder what has changed as I have had the splash screen enabled for the last 6 years.
