« Why Lightroom | Main | Move over 5D--I've got an iPhone now! »

I wonder why it takes so long to generate your previews in LightRoom? I'm on Windows. I haven't timed my 1:1 preview generation, but it feels 3 or 4 times faster than you describe. I'm converting to dng as part of my import process. I also will review and some editing while the import and preview process is happening.


From my experience, rendering 1:1 previews in Lightroom on a PC is really slow also. Your 29 minutes to render 118 of them from 5DMkII RAW files sounds about right. I am using XP 32 bit on a Quad core PC with 4GB RAM. While rendering, the entire machine is heavily burdened with the task. I really hope that Adobe can find a way to speed this process up.
