P: LR4 is slow to move photos from one folder to another compared to LR3

Moving 212 photos - 34 seconds.

It works for me.
moving 54 photos - 40 seconds.
moving using your workaround - 10 seconds.

LR 4.1, Core 2 Duo.

Ben, hope this isn't a duplicate reply. Looks like the original got lost when I signed in. Adobe may not like iPads.

LR 4.1, same catalog as I sent to you but with about 8,000 more pictures and a few more smart collections. Moved 22 pictures from one folder to another on my iMac.

Collection panel open: 60 seconds

Collection panel closed: 60 seconds

Quit LR, reopened LR. Collection panel closed: 2.4 seconds.

Adobe has more work to do to fix this. But it is much better than previous version.

When I test with the catalog you provided, I get the same slowness in both LR3 and LR4. Life is full of mysteries. :-)

Ben, I had virtually the same amount of Smart Collections in Lightroom 3 and did not have that slowness problem when moving files from folder to folder.

The specific issue that we fixed is that when you had smart collections that had folder-related criteria (Lance had a lot of these in his catalog), the smart collection query was re-running every single time a photo was added to or removed from a folder. This is what was making things so slow in Lance's case. This was not new to Lightroom 4, the same thing happened in Lightroom 3, so I'm not sure why Lance would not have seen the same problem in Lightroom 3 (unless Lance didn't create the folder-based smart collections until Lightroom 4).

There is no known issue with preview incompatibility between Lightroom 3 and Lightroom 4. There were a lot of other variables changed at the same time in Steve's steps (relaunches, catalog optimizations, etc.), so it's hard to say if rebuilding the previews is really what made the difference. Seems unlikely, but anything is always possible. :-)

Interesting. Prior to this, I had been advised by Adobe that a work around was to close my Collection pane, restart Lightroom and then work with the pane closed. That did speed up the transfer of files greatly. They said that I have a lot of smart collections and the updating of these collections were causing the slowdown. The new Lightroom release 4.1 seems to be working ok with transferring files from folder to folder. I think that it is working with the Collection pane open but I will check it again this evening.

I assume that Adobe is reading these posts, (although they remain very silent) and perhaps it will give them an additional clue as to what is happening.

Adobe has not handled the communication well during this problem. I do like the program.

I noticed the same problem; taking about 20 seconds to move a file from one folder to another on the same drive. Solution for me was to delete preview folder via Lightroom (Library>Previews), shut down LR4 and then go to the catolog folder via Finder (on a Mac) and drag preview file to trash. Start up LR 4 again and it creates a new preview file. I then re-rendered 1:1 previews, optimized catalog two times (not sure if that was necessary but WTH), shut down LR once more and reopended and VOILA!!!! Files moved to new folders VERY FAST (just as fast as LR3). Also 1:1 Previews seem to be rendering faster too.

I think what's going on is the previews file that you created in LR3 must have issues in LR4. Kind of a pain to have to rebuild my 1:1 previews again considering my library is currently 93,999 files (half of which are RAW 35meg) but that's what overnight-time is for :)

Hope this helps peeps cause the thought of living with such sluggishness was a real deal-breaker. I have to wonder why Adobe doesn't give a heads-up on this??

Ben,

I installed the RC2. On my Imac, I found that the moving of pictures from one folder to another was much better with the collection panel open. I tried it a few times and it seemed to be a fairly consistent moving time of about 2-3 seconds per file (jpegs). When I closed the collection panel and restarted lightroom, the files took less than a second each to move.

I tried a few things in the development mode and did not see any issues. For me, on my Imac, this looks like an improvement,.

My Macbook Air continues to work well with all versions.

Hope you guys are starting to get this figured out.

Thanks.

Lance

Hi Lance,

Even with the Collections panel open you should find it to be much faster than it was before. As I said, it's still not fast, and we're working on that, but it's nowhere near as slow as it was.

Thanks,
Ben
