Lightroom performance issues

[Bxbche]

I just completed a PC build to replace my 2010 dell laptop. I was focused on building a PC that would perform great for Photoshop and Lightroom 

 

my new PC has the following

i7 6700k overclocked to 4.4 ghz 

64gb gskills ripjaws 5 ram ddr4

gigabyte SOC force z170 MB

dual m.2 Samsung 950 pros in RAID 0 total of 1 TB

samsung 850 ssd 1TB

evga 970 ftw+ GPU 

nocturnal nh15

evga 850 psu

win 10 home. 

 

When using Lightroom to edit photos in develop module my new PC takes sometimes seconds to update the image to the current version. And when using a brush the updates lag dramatically. 

 

During this time my GPU and Processor are not even at full load ?????

 

What at is causing such poor performance? 

 

My new system has great benchmarks in cinebench ,other benchmark systems, and in Photoshop

How many photos do you currently have in your Lr library?  How are your 1:1 and smart preview generations?

 

What version of Lr do you have?

I generate 1:1 previews for the images I am editing and have done the tips recommended in other forums to improve performance.  I removed un needed Lightroom previews and smart previews   Turned off mobile sync increased cache size. Etc. 

 

Catalog size shows 9505 images. Total catalog  size 272.05 MB. Total preview cache size is 10 gb. Medium quality at 3840px resolution. Smart previews are 422 MB. 

 

I I turned off automatically update XMP. 

 

i have lightroom cc and I am using a dell 27 monitor at 4K resolution.

Hmm only 9000 images in your library, it shouldn't have any performance issues.  I have over 50000 in mine and it runes well.  Maybe it's an issue with the GPU trying to render 4K resolution?  Not sure.

I had saw some sites  that say Lightroom has performance issues with 30 inch monitors at 4 k resolution. Was hoping it was something else as I like the real estate provided by the higher resolution and did not want to go to lower resolution.  The other sites recommended zooming in while using a brush tool.  Any suggestions?

Update: I turned off a background app for my logitech mouse and keyboard that seemed to improve performance. Also i updated Lightroom to the version that was just released and also seems to improved performance for this issue. Thanks for the help.
