Bridge/Camera Raw: Make use of extra cores to process multiple photos in parallel

Actually it uses only 25% of my CPU performance. I've a Intel Core i7-2600 CPU @ 3,4 GHZ, with four cores and enabled hyperthreading, also eight virtual CPUs.

At least it could be FOUR times faster, if it would use all available cores, but so I get one preview per second (12 MP RAWs). So I've to wait in case of 1.000 RAWs round about 15 minutes. If would use all CPUs, which are available, it could increase speed up to 4 minutes. More then 10 minutes saved.

As it is experimental proven by users using Lightroom, it is possible to enforce at least Lightroom export to take use of all cores AND improve the processing throughput:

So it would be a great improvement, if Bridge would also take use of the possibility to process images in parallel, so the thumbnail and preview generation would be increased and the user is not forced to wait until the serialized processing has finished its work.

Also as another forum thread was closed as duplicate, it looks like, that if I want to have also the export of images processed in parallel by Camera RAW, I have to ask for it in the same request.

So please take advantage of our cores and increase the throughput.

It looks like, that we do not mess up our throughput by messing up the CPU caches, HD I/O, RAM I/O as it is pointed out there:

At least in Lightroom it is already working well, but the users have to enforce the parallel processing manually:

So why not use the possibly and and improve the thoughput?
