Description

The Windows version of 2.4 is significantly slower than the Ubuntu 2.4.

I runs really sluggish on my PC
- Intel i5 760 CPU
- 16GB RAM
- Windows 10

Meanwhile I installed Oracle Virtualbox on the same PC, I created a VM 2 CPU cores and 4GB RAM assigned. I installed Ubuntu 16 and Darktable 2.4 on it. Even with much less hardware resources assigned it still runs faster than Windows version with full hardware resource.

If you want to help improve the situation, please be more specific:
  • What did you do exactly (edited an image in darkroom or exported an image or browsed images in lighttable module)? There are lot of things you can do.
  • What do you mean exactly when you say "sluggish" (ie how much time did it take whatever action you tried to accomplish)?
  • Is your performance problem related to one image or a specific image module? If yes, it helps if you share the image in question and the XMP file which contains the editing steps

Also in such cases you can turn on the performance debugging, when you start dartkable with -d perf command line switch. It would be useful to share the result of that. For Windows the log is written to a log file, you can read it how you can get that file looking up in FAQ:

I'd suggest to close this due to lack of response from the submitter.

Right. We can still re-open once more info is provided.

Pretty much everything is much slower, especially in each edit module after I make some parameter change and wait for the preview. And image export is also much much slower than Linux version.

I can turn on the performance logging, but I am not sure how useful it will be because you want to compare apple to apple instead only see the result from one side. Do you think it will be helpful I try to record some video by using both systems to process the same image with same steps?

Sorry for the late response, all the email notification went straight into my junk mail folder. I happened to browsed the folder today and saw the most recent one.

Please show the performance logs Peter asked for. Without those we don't even know what we are talking about – is the processing slow, the GUI laggy, something else maybe?

I used the command line switches as instructed, but I am not able to find C:\Users\[username]\AppData\Local\Microsoft\Windows\INetCache\darktable\darktable-log.txt file at all. INetCache folder does not exist.

Depending on Windows version it can be elsewhere: https://www.darktable.org/about/faq/#faq-windows-logs

Also if you have darktable 2.4.1 installed you can use the command line switch --help, it will tell you very exactly where the log file will be written.

With 2.4.1 the log folder was created. I attached some activity here, but they are from 2.4.1 not 2.4.0 anymore.

My feeling is that 2.4.1 performance seems to be better than 2.4.0.

Your OpenCL is extremely slow. Please try disabling it in darktable's preferences. That might fix it for you.

I will give it a try. Do you mean by GPU is too slow?

#13 Updated by Tobias Ellinghaus 3 months ago

Possibly. What GPU do you have?
