#278 Quicklook plugin and Sierra.
Is anyone else having the following problem? I updated from the pre-retina DjView version to the latest version, and Finder has become really slow when displaying a folder with .djvu files. I also use Quicksilver, and it slows down particularly when the search result is a .djvu file. I feel that this has to do with the quicklook and spotlight plugins in the new app.

Can you confirm that pre-retina version of DjView worked well on the same OS?
Alternatively, you can check the file "Info.plist" that is located inside the DjView.app directory.
The last lines should read
<key>NSHighResolutionCapable</key>
<string>True</string>
You can try replacing "True" by "False" to disable the retina code.
Does this fix the problem?

Bugs:
#278I tried modifying the info.plist, but that did not help.
I did not back up the old non-retina version from a few years ago before updating (a few days back); could you please point me to where I can download a compiled app of the non-retina version from, and what that version should be?
Here is another test to illustrate the problem I am facing. Place a couple of djvu files in your download folder stack on the Dock, along with other files (PDFs, say). Then open the stack from the Dock, I am finding that the previews of the djvu files take a while to generate, while all other files display instantaneously. Also, when I double click to open a djvu file, there is a lag before DjView starts up, which I think wasn't there before.
Incidentally, another new problem is that DjView displays the first file on the right hand side of the screen, about a quarter of the screen height below the men bar, instead of at the left upper corner.
I am using Sierra on a 2012 retina macbook pro.
Try the 4.10.5 version in https://sourceforge.net/projects/djvu/files/DjVuLibre_MacOS/3.5.27%2B4.10/

You can also try this version, compiled with Qt-5.7 instead of 5.5.

#278Thanks, but that did not work. However, I was able to go back and redownload DjView 4.5 and all my problems have been solved now. It is superfast, and I even used the 'Retinizer' app to make the interface look good on screen. Spotlight, Finder and Quicksilver all list djvu files superfast now.
I suggest you guys take a look at this problem, at what changed post version 4.5 that could cause this sluggishness.
Which one did not work?
4.10.5
4.10.6+qt57
both?

#278Both!
Hi Leon, I seem to be having this exact same problem.
Hello Jeff,
This problem frustrates me quite a lot too. Nothing has changed in djview in that respect. What used to be fast is now slow. There are lots of hits on the web about slow quicklook. See http://wccftech.com/how-to-fix-quick-look-in-os-x-mavericks/, http://apple.stackexchange.com/questions/263309/quick-look-of-image-files-very-slow-on-macos-sierra, http://forums.macrumors.com/threads/quick-look-being-very-slow.1653397/. But none of them is super-convincing…
What I found is that the commands
$ qlmanage –r
$ qlmanage –r cache
get my machine to go into heavy computation mode. Quicklookd now takes 85% cpu. Will see tomorrow whether things are improved once this background task is done.

#278Seems that the thumbnail caching does not work anymore for some unknown reason.
I will try to revamp this very old code to make it work better.
Two workarounds.
$ qlmanage -r && qlmanage -r cache
This seems to reset the caching. The first view of a directory is slow but the subsequent views are fast. I also had to reboot before that worked…
$ defaults write org.djvu.qlgenerator thumbnail -bool false
You can re-enable it with:
$ defaults delete org.djvu.qlgenerator

Bugs:
#278I believe this is fixed in the latest binary release (DjVuLibre-3.5.27+DjView-4.10.6-qt57-intel64.dmg) which includes a resigned quicklook plugin. In fact I am not certain at all the djvu quicklook plugin was responsible for this. Googgling for "quicklookd eating cpu" reveals that lots of users had such problems without having djview installed whatsoever.
After installing the new version and running djview at least once, it may be useful to cleanup the thumbnail cache with command:
$ sudo find /var/folders/ -name com.apple.QuickLook.thumbnailcache -exec rm -rf {} \; -print -prune
followed by a reboot. Things seem to work better after that. The first time one use the Finder to display a directory full of djvus, it takes some time to generate the thumbnails. But they it gets fast because they are cached.
So in the end, why was it slow before? I doubled the performance of the djvu quicklook plugin, but I also believe that the very slow performance people reports is due to some other bug that makes the quicklook system loop...
Very nice Leon! I'll give it a try soon ...
This didn't help me, after using your command and rebooting, and browsing to a few djvu directories to allow caching, it still takes around 7 seconds to view a folder with ~10 djvu files.
Oh please fix that problem, it's almost impossible to work with djvu files. I am obliged to put all the djvu files in a folder never opend, and work with only aliases. It's such a pain... Thanks for us :-)
Sierra + DjVuLibre-3.5.27, Qt-5.7.0 (but the title in the About dialog is "DjVuLibre DjView 4.10.6" ?).
This problem has also been bothering me for quite some time now, but following Calc's advice and installing DjView 4.5 made everything run smoothly as well. I tried DjVuLibre-3.5.27+DjView-4.10.6-qt57b-intel64, but it was of no help.
Try removing the directory /Applications/DjView.app/Contents/Library/QuickLook and all its contents.
Then reboot, Does it improve the situation?
Sorry, not at all for me :-(
MacOS 10.12.5, DJView 4.10.6,
In principle, there should not be a djvu quicklook plugin anymore (you just deleted it.)
Therefore, if the machine is still slow, who’s the culprit?

I don't know it it calls or not djvu code, but yes, it's slow only on djvu files. So I guess something should go wrong on the djvu side ? My 2 cents.
I tried the command to completely disable thumbnail generation for djvu files,
but it's still making them and taking forever to load. Also tried reinstalling the old version 4.5 and it still was slow. I made sure to reboot and everything. I have no idea what my problem is at this point. Would believe it was a deeper issue with the OS except that it only happens with djvu files. Really frustrating, let me know if you have any more ideas..
xfacter: this is about my conclusion as well. This appeared with Sierra. The same thumbnail generation code in djview4.5 and djview4.10 gives different results.
xfactor: it may not be generating thumbnails but simply using those already present in the cache. Is something faulty with these thumbnails? I tried clearing the cache with
This makes the system slow for a while because all thumbnails (not just djvus) need to be regenerated. But after this, you sould no longer see djvu thumbnails anymore.
