Aperture is very slow with Snow Leopard

Yep, same issues here (and I'm on a Mac Pro). There are a few topics about it here. No solutions so far.

We've noticed that importing from SD card is a lot slower to our FW400 drive than it was before. We made a new library on the internal drive and that is ok. We vacuumed the FW drive, no better so we're now rebuilding the library to se if that helps.

My problem is that it is loading the thumbnails and has been all day. The pictures are the but I am unable to edit anything because the thumbnails are not loaded yet.

Same here. When Aperture worked, I liked it very much, but I think it's time I went back to Photoshop exclusively. At least I had an inelegant workflow that ALWAYS worked...

I now think the problem I have is a compatibility issue between my firewire 400 external enclosure and Snow Leopard, as any communication with it is painfully slow, even in finder. I connected the same drive using a USB cable and it is back to normal.

zemitch - I also use one of the slowest machines capable of running SL, but my your graphics card may be different than mine. But I also store my masters on an external drive and that wasn't the issue.

I found rebuilding the database of Aperture when starting up helps a bit, but the biggest improvement is to do cropping/straightening AFTER the other adjustments. That changes my workflow, but with no crop/straighten, the other adjustments didn't not show the horrible slowdown.

See if that helps you.

I'm also having an uselessly slow Aperture 2.1.4 even by avoiding Snow Leopard.

I have not been having trouble with Aperture until I loaded Snow Leopard. It is really slow. It would be nice if they would update it.

Mine is also painfully slow with lock-ups.
Took an hour plus to import 200 raw photos yesterday. Use to take minutes with old OS! Now that's improvement right!

Jeesh, think i'll go to Lightroom instead!

I'm trying the 30 day free trial of lightroom. You may want to give it a try.

I'm so over this Aperture Bull. It's supposed to be geared towards professional photographers and yet it's un-usable asis.

This is unacceptable in my book. They never advise to what is going on with bugs. We are always just supposed to sit back and hope it will work out!

My photography business can't run like that! My clients can't wait and wait and wait!

I read that the Firewire issue had been sorted with 10.6.1, but mine was still slow after the update. If any of you are using FW drives that is very likely the source of your slowness.

I have noticed that all my programs are slow with SL 32 bit. Are you running in 64 bit? If not try rebooting while holding down the 6 and 4 keys to boot into 64 bit. See if that helps. It makes my programs run faster.
