I work with scanned film, which gives much larger files than a 36mp camera. 16bit RGB scan of a 35mm neg is 128mb and a 6x6 neg is 470mb. That's with no editing or layers, which make the files a lot bigger. My machine is FAST. I have not looked at it to see the % of CPU being used, but I know it runs filters and stuff extremely fast. Almost instantly on 35mm and in a few seconds on the giant medium format scans. My processors are not that much faster than yours, but I do have 12GB of RAM. I wonder if more RAM would help you, it did speed mine up quite a bit when I upped it from 4 to 12 GB. -- Chris Crawford Fine Art Photography Fort Wayne, Indiana 260-437-8990 http://www.chriscrawfordphoto.com My portfolio http://blog.chriscrawfordphoto.com My latest work! http://www.facebook.com/pages/Christopher-Crawford/48229272798 Become a fan on Facebook On 8/12/12 3:04 AM, "John McMaster" <john at chiaroscuro.co.nz> wrote: >It is far slower to work on D800E (lossless compressed) 40MB files than M9 >(uncompressed) 36MB files. > >I have a reasonably grunty machine so I went looking at what the >bottleneck >is...... > >Mid-2009 Mac Pro (2x 2.26 quad-core Intel 5520 CPU) was running at over >1300% CPU (16 threads available) briefly while doing minor changes, be >aware >of this limitation if thinking of upping your camera MP ;-) > >john > > > >_______________________________________________ >Leica Users Group. >See http://leica-users.org/mailman/listinfo/lug for more information
