LS: Why is Smart Update so large?

Just curious, but if I run SD! (2.6.1), surf, e-mail, and then run SD! again, some 2.5GB are updated. In 10.5, less than 1GB would have been updated. Seems odd, at least to me (but, what do I know!).

We've had some reports of this, and we're investigating to see why some files under Snow Leopard files are comparing different when users indicate they haven't really changed anything.

Better copying too much than too little, though.

After Snow Leopard update it does take longer to Smart Update

I upgraded to Snow Leopard Friday evening. I ran disk permissions before and after, of course. I also did a complete erase & backup with SuperDuper ... which took about the usual time for me ... 60 gb of files ... a little over an hour on USB (newer MacBook but without FireWire).

I just now ran Smart Update (which I do every 24-36 hours BTW); and Smart Update took almost 30 minutes. It normally takes about 5 minutes ... no more than 10 when I've changed a lot of files during the day.

No complaints. I still love SuperDuper ... couldn't live without it ... but it does take longer now.

Let's see if this changes over time. We're investigating what might be going on, but it's not clear at present, certainly not something that would change 5 minutes to 30...

Smart update taking a long time to complete...

I'm also hoping that the cause of slow smart updates with a Mac OS X 10.6 / SD 2.6.1 configuration gets attention. My 250+GB boot drive clone has gone from about 10 minutes to almost 20, but worse, my nightly 800+GB Time Machine clone has jumped from under 4 hours to over 9... and this is on an 8 core 2.8GHz MacPro talking exclusively to internal SATA II hard drives.

After discussing this with Dave, there's nothing different in what SD 2.6.1 is doing, so hopefully there will be some "a ha" moment and a 2.6.2 will appear that returns smart update's efficiency.

I literally ran SmartUpdate with SD! 2.6.1, rebooted, and ran SmartUpdate again. Amazingly, over 2 GB of my 35 GB drive were updated. Hmmm

I think this MIGHT be a side effect of prebinding. We're looking into it.
