sooooo slow....?

[gaurish]

After i make quite a few (delightful) adjustments, specially some gradients and brush local adjustments, lightroom becomes sooo slow... Even to move an adjustment slider takes time (the spinning wheel shows up) so it is impossible to set it properly... Am i missing something? I have a macbookpro with a 2.4Ghz processor and 4Gb ram, HD is half empty, no overheating, lightroom is run in 64 bits mode... Any clue? Thanks

Hi gaurish, welcome to the forum! Have you tried upgrading to 2.5 for a start? And what camera are the files from?

 

[gaurish]

forgot to mention that i do relaunch and optimize the catalog all the time, and it helps for a few minutes... I also do the dng preview and metadata update. I have lightroom 2.4 (i just read about the 2.5, no performance improved. Am i wrong?) Well you made a point asking witch camera: the 21mpx canon 5dmk2... Must be the reason right?

You might try running in 32 bit mode and see if your slowness disappears. It is a quick change to make on MAC and easy to change back.

 

[Victoria Bampton]

Ah, yes, the 5dMk2 could well be the reason. It starts to slow slightly even on my Mac Pro on those files. They are huge, and the local adjustments are very processor and memory intensive.

I would still try it in 32 bit mode and see if it isn't a little quicker. Some operations are marginally faster in 64 bit and others are slower.

For you Mac folks, are the well-known nVidia setup tweaks specific to Windows or do they affect Macs as well? I ask, because that drastically affected local adjustment performance on my older Windows system.

32 bits didn't help... 26 seconds of spinning wheel to switch from the library module to the develop module! I am monitoring the cpu and memory's work and noticed that though the cpu is doing its maximum, the memory remains in the hammock (meaning is not full throttle) Any tweaking options here?
Another thing i just noticed witch has noting to do with this topic but is interesting to point out is when i brighten the image with the adjustment brush with the automask on it leaves huge amount of specks like people got leprosy! I've re-done the brush without the automask and it disappeared...

 

[gaurish]

As soon as i can i will try similar work on a 1'Mpx file to see if it is any better... btw, my ram is ddr2, would the ddr3 solve the problem?

 

[Victoria Bampton]

You'll also find automask slows it down incredibly, as it's very processor intensive.

I've noticed exactly the same and wondered about it, but now you ask the question, it makes sense! If you look at the image at 4''%, you'll see that what looks like a continuous tone is actually islands of different tones, especially on skin. So the automask detects these differences and applies the correction to a finite range of tones, leaving islands that are outside that range. Without the automask, it applies the correction universally. I think!
