--- Comment #17 from Ralek Kolemios <i...@ralek.art> --- Created attachment 151083 --> https://bugs.kde.org/attachment.cgi?id=151083&action=edit Slow stroke completion > Do I understand that correctly, if you just load a lot of documents that > occupy 30GiB of RAM, Krita is not sluggish, but if you work for a long > period of time with these documents, Krita becomes sluggish? Yes. I can make Krita use a lot of ram quickly, but even if it's using 40+gb of ram, it doesn't inherently mean it's sluggish. I've felt it get sluggish when it's been as low as 10gb of ram, and I can also make it smooth while also using 40gb. > If yes, should these doucments (you work with for the long time) be huge in > size? Or any documents will work? The sluggishness only seems to happen with larger documents. This could be correlation though, as larger documents are the only ones I work on for more than 4 hours at a time, while smaller ones usually get finished before then. > 1) What value do you have set in "Undo Limit" option? I have it set to 700 > 2) What maximum size you have assigned to the swap file (on the Performance > tab)? I think when I noticed these first issues cropping up, it was set at 50% or 40GB. I've since changed it to 10GB, but it's hard to tell if it's made a difference as I've had a string of smaller projects recently. >Could you explain in more detail, what do you mean by "sluggish"? Some >specific tools work slower? Or zooming/panning? Or menus? The entire program acts as though I have a worse processor installed. Basically everything that takes time takes more time. Brush stroke rendering, undoing, redoing, filters, hiding/unhiding layers, transforming layers, magic wand, fill tool, etc. I don't notice a difference in menus but the difference may be too small to be noticeable. Panning and zooming doesn't seem to be affected *as* much, but it does seem ever so slightly choppier. > Perhaps you could make a video of this state? Next time I notice it happening I definitely will take more videos, it's just a bit difficult for the large stuff such as transformations as much of what I draw is inappropriate. Right now I only have video of the brush 'stopping' after every stroke, which is usually a sign that Krita is in this 'state'. Compare the two attachments I have added and notice after each stroke, the brush circle stays behind, as if Krita is processing something now that the line is completed. >1) Go to Krita settings, Performance and set "swap undo after" to some really >small value, like 50MiB >2) Restart Krita >3) Open your standard huge document Unfortunately not. Manipulating a large document is still snappy when I first open it. My swap file is on a 7gbps read/write drive so I kind of figured that shouldn't be bottlenecking it. I'm going to be working on some larger documents soon, so I'm going to set my `swap undo after` back to 40GB, and up my undo up to 1000 and see if I can get it acting up so i can do some tests.
