Thanks Partha. As I said at flickr, I did a reinstall because the 2.9 install messed up my 2.8.2 install.. 2.9 still gives me a resolution error on some tifs when I open them. (The ones I've tested are dng's converted using Irfanview)..
I responded to this on Flickr.
I assumed it would be slower with gegl and 16bit, but this is definitely too slow.. Hopefully still room for improvement. Could you help me understand why it's this slow in gimp, yet when in delab for instance it's not slow at all? Even when I load jpegs in 2.9 gimp, it's painfully slow for every function.
This should not happen. Jpegs are 8-bit and so loading should not be an issue. Definitely room for improvement. 2.9 is work in progress and will remain so for awhile.
Delaboratory uses a completely different mechanism for loading files. It's written from the ground up to deal with 8/16/32 bit color. Gimp is loaded with a lot of legacy baggage which will take time to fix.
I'll try to hold out before moving back to 2.8.2 just in case there is anything you want me to check/test.. I'd like to have them both installed? Any recommendations for that? Installing 2.9 definetely hurt my Partha 2.8.2 install. I was getting errors (lib something dll errors). I wish I would have taken a snap of it but I didn't.
Sorry about that. Definitely urge you to use 2.8.2 for production work and 2.9 for playing. Please use the portable version of 2.9 so that you won't have to mess your 2.8.2 installation. 2.9 does not touch your personal space (.gimp-2.8) and so will not have messed your personal stuff. During first run 2.9 simply copies over your settings.
