Lightroom 6: Slow on my Windows 10 PC

Hi All,
I just got Lightroom 6 and it is really underperforming in everything - from boot time, the develop module, rendering and even switching the panes. I am running it on a Windows 10 machine, with Core i7 with 4 cores, 16 GB ram, SSD and a GeForce GT 750M GPU - so quite a performing machine. Even Photoshop (CS3) is running blazing fast, compared to Lightroom. Any update on the horizon to fix this?

You'll need to be more specific... exactly what is going slowly and how long is each action taking. And do you have the latest GeForce driver from the manufacturer?

I have updated just a few days ago my drivers and this actually fixed a lot of crashes of the application. Basically since then I experienced no crash at all.

Regarding specificity - I will try to post some numbers here, however the whole app feels just slow. Especially, compared to what I was used to with Photoshop or even how the app looks like on Julieanne Kost's videos, when she navigates throughout the ui and applies things like filters and so on.

Startup time: around 17 - 20 sec
Change of pane 1 - 3 sec, depending on what happens
The whole Catalog folder is less than 50 MB (as I just started)
The preference to use GPU is on and the NVIDIA card is selected/displayed

There are no other metrics I can share that would make sense, because of the great variability of sizes of RAW and other variables. Overall the application just feels sluggish and definitely not anywhere near the Camera Raw module from Bridge (again CS3).

I am running a 3 year old Win 10 machine with much less horsepower than you.

Start up time is about 15 seconds. (This is mostly disk i/o speed dependent)
Changing from module to module is less than 1 second.
Catalog is 6 GB (280,000 images)

We would need additional examples of specific operations and the seconds it takes to perform each to give you any helpful advice.

I'm having a similar problem as Gianluca. I have an i7 4-core 3770k, 32 GB DDR3 RAM, AMD 7950 GPU with 3GB DDR5 RAM, and SSD drive for the catalog. In other words, it's a fast PC! LR starts off pretty fast but after a few minutes of usage, it starts to crawl to the point it will even react to mouse clicks several seconds later. When checking resources (CPU, RAM, HDD, GPU), nothing is maxed out, not even past 50%... yet LR crawls.

Sorry Gianluca can't help you, hope we both find an answer :)
