Hello all! So I am in luv with Darktable. I have been photo/video/editor since '95, and the features and potential of this package is amazing. The big improvement I feel Darktable needs right now is the speed of the tethered images coming in. I have made some settings such as checking 'performance over quality', enable 'disk backend cache,' etc. I've done some comparisons and logged my data on several different systems, os, and camera bodies. I can share this data in great length and detail in an additional response if anyone shows interest in that info (multiple desktops, laptops, camera bodies, and OS), but in summary, on a decent computer (say my macbook pro M2 14,7 computer Darktable 4.0) Darktable runs about 5.7 to 6.2 seconds from shutter click to review, and by way of comparison Lightroom is about 1.8 to 2.2 seconds from click to visual review. On a dell intel 4x pentium silver n5000 running ubuntu studio 22 and darktable 4.0, from shutter to review is about 9.2 seconds. On windows in capture One, that dell is about 4.5 to 5 seconds. These speeds are with a Nikon D800 with an average Raw file of about 40 megs.. Using a Canon 5d mkiii those numbers of time are about 25% faster, likely related to the smaller raw file of the 5d.
So... is there anything on a User side that can be done to increase the speed from shutter to review inside darktable? Or is this the magicians in the developer realm that can only handle such feats? If so, is there anything I can contribute to assist in gaining a faster tether review? All input is appreciated and respected.
