I’ve been scanning negatives at the max resolution and 16 bit color depth lately. This gives an initial file of about 220 Mbytes. As soon as a curves layer is added the size doubles. In addition the history takes memory too. So pretty soon the file needs to be paged out to disc. This is about 100 times slower than RAM based operations and is generally limited by the mechanical speed of the disc drive.
There seems to be a practical limit of about 1-2 Gbyte for RAM so at some point the disc swaps are going to occur.
So, while parts of the edits may be faster with higher CPU speeds, it would seem that overall there will be slight improvement once the files start getting written to the temp disc.
Has anyone any experience with this?
Presently, with my 450MHz processor I can wait 4 or 5 minutes for the edited file to be saved.
