RT 5.4 Performance optimizations?

Software RawTherapee

So, it’s the loading of the list widget that’s slow… ?

46

Loading the DB is instant, it’s the widget that’s slow:

47

wxWidgets has a ‘virtual’ mode for their listbox, which only loads into the list the rows that are visible. I don’t know GTK, but it might have something similar.

I haven’t felt the need to use it for rawproc’s lensfun integration, however; it takes a second or so for the dialog to come up, but it isn’t onerous…

Hey guys,

For what it’s worth, I’ve given up and continued using 5.0 with GTK2. I don’t know if newer versions have any features that 5.0 is lacking, but the performance issues are totally keeping me from even considering going back to it.

5.0 with GTK2 works great, blazing fast.

EDIT: As an interesting tidbit, I haven’t noticed resource consumption on RT 5.0 GTK2 (32-bit) that would mean the 32 bit architecture was throttling it. Memory usage and CPU and all the good stuff is well below limits. Runs super light, actually. So I don’t mind that it’s 32-bit. It runs super smooth.

It seems clear that on some HW/SW configurations, RT GTK3 suffers from slowness (when starting, switching) whereas on other configuration there is no problem.
On my PC tower (I7 6700K, motherboard Z170A, 16GB DDR4, SSD) which is not blazing fast, Starting time is about 2s, and I cannot reproduce the above lag with 10 edit windows opened.
Why such different behaviour?

I agree! But: rt 5.0 gtk2 unfortunately cannot handle compressed RAF from an X-Pro2. :frowning:

Is there – or will there be an rt 5.4/gtk2 from Windows :slight_smile: ?

@gaaned92 To reproduce the lag I have to expand the following tools:

Yes that what I did. To be sure, I repeated the test with 4 images in METM.
For each image the 2 tools are expanded with a correction for each image, manual or auto.
I minimize the RT window, go in other apps , expand the RT window.
There is surely a lag, but unnoticable in normal use. All adjustments react normally.

@gaaned92 Can you provide your options file?

Thank you very much for the options file. Now I know why you can’t reproduce the lag.
It’s the theme. You use ‘TooWaGrey - Average Surround’, which is fast. I used the default ‘Rawtherapee’ theme, which is slow. Now we need to find out, why ‘TooWaGrey - Average Surround’ is so much faster.

GTK3 UI rendering performance should be significantly improved in commit UI rendering performance improved · Beep6581/RawTherapee@b626b4e · GitHub available now in the dev branch.

1000 kudos for this :)))

In the TooWaBlue theme text-shadow has always been off. I never noticed a speed difference between the TooWaBlue and RawTherapee theme.

That may be a reason your themes have been faster…

Would removing unneeded dcps and icc profiles also help, or is there something special about lensfun?

I changed skin to TooWaBlue also. Seems to help indeed.

I was having issues with running the program and tried changing the editor mode in the preferences/general tab to Single Editor Tab Mode and Multi Editor tabs mode and it sped things up a lot for me. It is usable for me now. Not sure if I missed someone trying this above. I am new here and the program.

Hi Chris and welcome!

What kind of RAW files are you working with? Could it, for instance, be compressed RAFs from a Fuji?

Operating system, computer, CPU, RAM, &c?

Have fun!
