So I’ve run into an interesting problem. I had a laptop that was roughly 4 years old with an i7 quad-core (don’t remember which one exactly) which ran darktable really well - even things like denoising were pretty smooth. Recently, it died so I bought a new laptop, also with an i7 quad-core (i7-7700HQ). Everything else seems to be really fast, but darktable seems to be really slow, even just reacting to things like mouse-over events (like when I hover over a picture in the lighttable module, for example). I thought maybe it had something to do with powersaving mode, so I switched the cpu governor and the perf-bias and everything (even switched to a realtime kernel since I prefer to use that anyway), but nothing’s helped. I’m not quite sure how to debug, but I can provide logs or run and/or compile things to test. Oh, and the version I’m currently using is the one compiled for the Debian sid branch (so some version of 2.4.0).
[Edit] Tried compiling my own version and still running into the same issue. Currently running
darktable-generate-cache to see if that will help. It could just be that
darktable is trying to generate the cache while also attempting to be responsive to me?
