Working with RAW files on my C2D Mac Mini under iPhoto 09 is an absolute disaster. For example, just rendering one full screen RAW file typically takes around 15-20 seconds. Moving any of the simple adjustment sliders also takes an excruciating amount of time at around 5-10 seconds per slider movement. Clearly this is completely unacceptable for a full workload of several hundred shots. Would Aperture work any better with RAW shots, or would performance be the same? I use PS, and occasionally ViewNX2, and neither take nearly as long. My machine "only" has 1gb of RAM, so I am guessing that is where my bottleneck is. Another thread said users should have at least 4gb for aperture, which wouldn't even be possible for this machine. Any advice on whether Aperture would be viable for me? Thanks!
