Hi
I am dealing with Canon 5D2 raw files and I find slowness when:
Loading full screen preview (10-30 seconds)
Loading image into Develop (40-120 seconds) I am talking about being able to use brushes etc.
Loading 100% preview (40-120 seconds)
Exporting a Tiff file (around 60 seconds)
All of the above slow significantly if a file is being exported.
Thanks
For your help!
Have you generated 1:1 previews before you start editing and viewing your pictures? This is absolutely essential for performance. Do you see a difference in performance when you run Lightroom alone on the PC with no other apps active?
In comparison here are my subjective timings on my MacBook Pro
Preview generation: 10 seconds per picture
Loading full screen preview (1-2 seconds)
Loading image into Develop (5-7 seconds) depending on how much editing already took place.
Loading 100% preview (1-2 seconds) zoom in on already loaded full screen view.
Exporting a Tiff file (around 20 seconds) in full resolution.
Exporting a JPG in 1200x800 around 12 seconds.
And all on 1Ds mkIII RAW files and all on 30" screen at 2560x1600 resolution.
So when I haven generated previews everything is pretty fast and feels instant except going into develop to be ready to edit a picture, but that's ok with 5-7 seconds.
Remember my MBP is the old model from 2009. The new 15" has a quad core option with the i7 cpu which will more than double the performance compared to mine. But so far I have not found that performance increase justifying an upgrade. Even though I have a quad core Windows 7 machine I hardly ever use it any more since I find it so much more convenient to have a single machine (laptop) that I can bring everywhere. When I'm out on reasearch or doing workshops I can bring all I need with me and when I return from a shoot with possibly thousands of pictures they are all (at least partially
) rated and partly edited and all previews are generated so I can plug the machine into the 30" screen and continue. Before I had to move all the images from the laptop to the desktop machine and it took quite some time. The other thing is that except for preview generation of heavy exports that require a lot of cpu the MBP is
completely quiet which is a thing I
really like.
