Or if you can, send me a link to the file so I can test if the speed is really abnormal on macos compared to other platforms.

https://bugs.kde.org/show_bug.cgi?id=421584 --- Comment #4 from Manga Tengu --- Sadly I don't have a linux with a comparable CPU. I wish I could mail the original it but it's too big. So I made a few slimming operations and tested the performance along the way which led me to interesting infos: I flattened the image -> still as slow I made the image 2/3 of the size, it got from 45 to 35 seconds I filled the layer with solid white -> saves in 1 or 2 seconds. This is proportional to the size of the file btw. So My guess is the more the final image is complex and fragmented, the slower it gets. The more solid color zones there are, the faster it is... I'm mailing you the flattened reduced file so it's a tad lower than 20 mb and fits gmail. (still the image is slow and complex -> 35 sec per save). Fill it with white, it will save fast. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=421584 --- Comment #7 from Manga Tengu --- No I didn't, but I also tried manually trimming the file before saving as It was bleeding a lot -> no noticeable change.

https://bugs.kde.org/show_bug.cgi?id=421584 --- Comment #10 from Boudewijn Rempt --- Hm, that's a pretty simple image... And it does take quite a bit of time saving, though not 40 seconds. Let's see what's going on here... -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=421584 --- Comment #11 from Manga Tengu --- yes originally it was bigger and had lots of layers but it was too big to share via email or here. (didn't think of drive). So I simplified it and realized it was still very slow. 43 seconds seconds to be exact on my configuration: 2018 macbook pro 15` with a good cpu. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=421584 Lynx3d changed: What|Removed |Added CC||lynx.mw+...@gmail.com --- Comment #12 from Lynx3d --- Okay I dug a bit into this, for me it was mergedimage.png that ate the most amount of time compressing, and the reason is apparently that since this commit 4d609a56ef572b22ec9a712985e1927c7a0143d0 the compression level is now Z_BEST_COMPRESSION (level 9), because KoQuaZipStore::setCompressionEnabled(true) set this, while initially it is initialized with Z_DEFAULT_COMPRESSION (-1, which apparently is 6 internally for zlib). Using Z_DEFAULT_COMPRESSION gets the save time and file size pretty much identically to the old code used in krita 4.2.9 on the file I tested. The file size difference was pretty much negligible btw, ~200kB for a 23MB file for taking 3-4 times longer to save. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=421584 --- Comment #13 from Manga Tengu --- This is very interesting indeed. Leads me to think the following: In my comics workflow I have LOTS of files and I do save a lot. Since the compression difference is not significant, can we configure krita through ui settings to compression to 0 ? Can we even save files without mergedimage.png embeded files ? Then being able to command line krita to generate those mergedimage.png on demand would be very welcome. Would that affect thumbnails btw ? -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=421584 --- Comment #14 from Boudewijn Rempt --- The strange thing is, that _is_ a setting, "compress kra files more", so I'll have to check why this is happening, because it's off by default. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=421584 --- Comment #15 from Manga Tengu --- Yes but what I understood is default level is 6, and "compress more" is 9. But as an extrem saver I'd like to know if we could set the level with a slider rahter than a checkbox so we can chose from 0 to 9 ? -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=421584 --- Comment #16 from Boudewijn Rempt --- That's for formats like PNG and JPG, not KRA, and apparently it's the compression on the KRA file (which is a zip file) which is the problem, but that should be off by default. I'm looking into it now. -- You are receiving this mail because: You are watching all bug changes.
