LR CC 2015.6 - Preview doesn't use Multicore.

Last week i swapped my CPU from i7-5820K to an i7-6900K, which is an 8-Core Broadwell-E. On a full patched Windows 10 with all Drivers, etc. RAWs from Canon 5D3 and 5Ds.

Curios what LR utilizes from that available CPU-Power i always have a look at the TaskManager what happens for all cores.
Exporting two or more Tasks at once (always 200 Pictures) works nice, but not at really full power like we were used in the first CC-Versions. *sad*

OK, Exporting seems to use all cores. (At the top left you see what happens at it jumps three, four or five Pictures, i hope you know what i mean.)
But generating the 1:1-Previews is sooo slow. Oooone aaaafteeer *yawn* aaanother... It uses just one core and nothing else. Hmmm. Year 2016... Really?

Please Change that annoying behaviour.

From where the hack did you got your hands on 6900K? :-)

I am intending to go that way configuration-wise, myself. 

Will check back on next sub-version of LR. I hope you will report. Because I see no other reason to upgrade both my current Motherboard and CPU (6700K). I have no other use of it aside LR.

Additionally you may check this article, check the graphics: above 4 cores no further improvement in various operations. Let aside that local adjustment/spot removal are even not included there.

Bought the CPU last week, arrived on Friday here in Germany, happy. :)

Before i had the 5820k on LR CC 2015.5.1 - it worked better aaaand used the 6 cores. Not the way it could, but it used them. On further version LR was way speedier. Look here:

As a semiprofessional i need the power. Additionally i'm editing other photographers weddings. So i need all the speed i can get.

Hups. :)
But have a closeer look at the Export-Benchmark (the last one) where LR utilized all the cores. Please note that this is a former version. LR slowed down from... 2015.3 if i remember right. Or 2015.4.

Bought it at Vibu for 1088 Euros. www.gh.de

10x 4 info.

For me export is not that bad. Usually when I am there (finished a set of photos) I take a break. So I am  not  on the computer during Export.

However in my workflow I use local adjustments/spot removal heavily. Unfortunately NOT reflected by Matt. I think I wrote them to provide test results on your CPU somewhere with local adjustments exactly. 

If you like and have a few free minutes to spare you can further check on my thoughts about it. Check this and this.
