Photo Mechanic 5 was giving me horrible performance writing to network disk (which is all my disk)—it would take 15 seconds or so to update the rating on a photo, for example. So I was still using version 4 on my desktop (I had switched to 5 on my laptop, where I’m nearly always accessing the local disk).
As I have been doing now and then, I upgraded to the latest V5 today, and ran a quick test—and was very pleased to find that it now updates ratings of photos on network disks quite promptly. Rotation also works fast (that was actually the first place I noticed this problem, back when). (I’m sure I haven’t been hitting every upgrade, this could have been fixed a while back.)
So, kudos and thanks to Camera Bits from me today!
