P: Make use of extra cores to process multiple photos in parallel

So the similar feature request for Bridge and Camera RAW is now:

The same issue is there, if you use Bidge and Camera RAW:

Yes, especially as they could ensure, that x processes are working in parallel.

performance on LR5 is very bad and this doesn't work any more so good as it worked with LR4.

I've similar issue during importing more then 2,000 files:

Windows 7 SP1; 64 Bit
Intel i7 with 4 cores, enabled hyperthreading and 3.6 GHz
-> 8 virtual CPUs
24 GB RAM

Only up to 25 % of my whole CPU resources used by Lightroom, so it took up 20 minutes.

If it would use all cores, it could do it 4 times faster: also only in 5 minutes!

Some for updating the previews after changing pictures. One preview after the other was updated. No parallel processing. Only simple and slow sequencially processing.

I'm really disappointed, as multi core CPU are not rare anylonger since years!

When exporting a webgallery the workaround to do it in several parallel jobs often doesn't work (as it does with the normal picture export).
For me this means that the hint can just be a workaround and Adobe should focus on optimising the use of ressources with multicore computers.

This would be ideal! leave it up to the user. There are times that you want to be able to use your computer for other tasks, and there are times when you would prefer to max out your system resources to finish your export asap.

exactly! You can force lightroom to do this by breaking up your export into several groups and exporting them simultaneously... For the record adobe camera raw when hosted in 64 bit photoshop exports photos in the way we're requesting.

I'd like Lightroom would definitely make something better with my CPU, multithreading and multitasking itself. Speed up the exporting process or let people make a good use of OS multitasking capabilities!
E.g.: I'd like to work on a different catalog (a different wedding for example) while exporting my 1.000/2.000 images set(s) of the first catalog.

Dear Adobe, please respond to this post. I think all we want is an honest answer as to why your program does not work in this fashion. If you are working on it, wonderful. If you don't have enough resources, let us sign up to support this initiative. If there are other considerations we have not brought up, please discuss.
