Lightroom CC: File handling much slower
I'm having an issue with Lightroom CC being very slow at file handling. In Lightroom 5 I could move files from one folder to another on the same drive very quickly (almost instantly, never more than a few seconds), but in Lightroom CC I'm currently moving 400 CR2 files to a different folder and it's taken 10 minutes. This is on a Retina MacBook Pro with an SSD.
Also, the way Lightroom CC converts to DNG seems to be different. Normally when I import files I choose to convert to DNG in the Import dialogue. Normally in Lightroom 5 I ended up with a folder full of DNG files. However, in Lightroom CC I seem to get a folder of CR2 files which are then converted to DNG. I tried moving these files (from within Lightroom) while this process was going on and Lightroom got very confused and around 25% of my files could no longer be found by Lightroom (they were still on the disk, but with "DNG" extensions as opposed to the "CR2" which Lightroom seemed to be expecting, even though it had just converted them!).
Overall, this has slowed my import workflow down hugely. I used to Import as DNG, move my files around and boom, done. Now I need to import as CR2, then move the files into the right folder (which takes at least 100x longer now), and then convert to DNG. Not good!

Thank you for reporting. We will look into this.

I don't understand your workflow in the last paragraph. When you move files do you mean moving within Lightroom or within the OS?

The old 5.x way simply read the CR2 file off the memory card and then wrote the file back to the hard drive in DNG format. This required only one hard drive write per file.
The new method reads the CR2 file from the memory card then writes the CR2 file to the hard drive and then reads the CR2 file from the hard drive and then writes it to the hard drive again in DNG format and then deletes the original CR2 file from the hard drive. This now requires two hard drive file writes and one delete process per file.
How can anybody think this new way is faster than the old way? This slows down the import process tremendously. Importing and converting a card full of raw files now takes 3 times as long.

I have a gone through all of the standard performance guidelines and have not improved anything. I do need to try deleting the preferences file and perhaps removing my color calibration software and it's profile.
I have a 4GHZ 8 core AMD cpu, and 16 gig of memory, two SSD hard drives. What more can I do?

Not the speed breakthrough we were expecting according to Adobe announcement...

This weekend I will try some different things, such as moving the catalog and camera raw cache to a different drive, trying different options for rendering image previews, anything I can think of.
A few people are using a RAM Disk to store the catalog and it works well for them, but is there any advantage over an SSD?

Also, Lightroom won't use my GPU - Ok it's 4 years old but the drivers are up to date. I can't be the only person using a 4 year old PC.

This clarifies where any potential speed-up should happen. There are bits of useful information further down the page as well.
Info. here as well. http://www.diyphotography.net/adobes-...

For me the solution was to pause the face detection indexing, which seems to be indexing every photo i've ever taken.
15 seconds after I paused it , Lightroom was converting one CR2 file every second or so.

Here's my question: WHERE THE HECK IS ADOBE IN COMMENTING ON THIS? We vent in these forums and are relieved to see these problems are not happening in isolation, and yet we have no evidence that Adobe is even paying attention to us.
I've put the problem directly to them and have not heard anything back.
