...I wanted to do a comparison test between the two machines. I found however that the newer machine was actually slower during processing but not importing. These were the times to import 192 raw files (3.3GB) - To finish copying and importing Intel i5 took 2:49 minutes Core Duo 2 took 3:39 minutes To finish copying, importing and processing Core Duo 2 7:00 mins Intel i5 - 7:25 So where the i5 was 50 second faster on the first task, it finishes 25 seconds slower overall, how is this possible? I've probably done something wrong. The specs were as followed: 13" MacBook Pro with i5, 2.3Ghz dual core, 4GB & 500GB 7200rpm drive (HD Graphics 3000). VS 13" MacBook with Core Duo 2, 2Ghz dual core, 3GB & 320rpm drive (GMA 950). So in every respect the i5 should win easily, but it didn't. The only difference was that the MacBook Pro already had another 3000 raw files in the database. But I can't see how that would affect performance to that degree. OR can it? I'm going to fill up the old machine with the same library and return, but if anybody has another idea, I'm interested.
