Performance issues with LR6/CC

I have been working with LR since LR3 and was generally satisfied with the workflow and performance. Currently I am still using LR5.7 with no problems. As I intend to by a new camera which is not supported anymore by LR5, I installed LR6/CC for testing the software before buying (as usual).

The download and installation went fine. LR5 catalogue was integrated in the new software after some minutes. So no any trouble.

After 1-2 hours working with LR6 I realized that several functions in the develop module are working slower than before, though my graphic card is supported.

With disabling the use of graphic card it works slightly faster (?) but it still takes longer than in LR5.

Also the 1:1 rendering after importing files takes almost double the time.

Understanding that LR6/CC should have a better performance than LR5 I am wondering, what went wrong.

I it helps to understand the situation, here a some features of my hardware:

Intel I7 Skylake CPU (4.0 GHz), 32GB DDR4 RAM, 800GB PCI-E SSD, GPU AMD Fire Pro W5100 4GB GDDR5

Thanks for the link, I have read the English version and honestly, I think this is more marketing than technically correct. (It's not hard to find many other examples of words written by Adobe that are not technically correct.)

Here's what is said in English: "Import and perfect your photos faster than ever. Lightroom takes advantage of compatible graphics processors to boost its overall speed, especially when you’re enhancing images in the Develop module." It's not clear if the words "faster than ever" applies to both "Import and Perfect" or just "Perfect".

You can also read what the lead software engineer for Lightroom, Eric Chan, had to say about what the GPU can and cannot do, and he specifically states that the GPU will not speed up importing, and the GPU only affects some operations in the Develop module, it does not affect "overall speed". GPU notes for Lightroom CC (2015)

So again, unless there are some changes that affect speed that are unrelated to the GPU which I am unaware of, I am very skeptical that LR 6 is supposed to be actually faster in general than LR 5.

Perhaps we will never really resolve this and know what Adobe meant by the above statement.

Be specific. What functions are slower?

Be specific. What graphics card? (And what is the size in pixels of your monitor?)

Intel I7 Skylake CPU (4.0 GHz)

Be specific. What is the exact model of your CPU?

Thank you for the reply. You asked me to be more specific. Therefore I took the last two hours to make a small test.

Functions:

I made 96 photos with my old 5D MK II this morning and imported them in both, LR 6 and LR5.7.

Afterwards I tested some functions in the development module.

I started with LR6 on a clean PC (i.e. just switched on, no further software running). After this I closed LR6 and started directly with LR5.7 (no PC reset in between)

Here are my results:

Library module:

Importing 96 pics from CF-Card: LR5.7 - 60 sec LR6 - 45 sec

1:1 Rendering: LR5.7 - 7:33 LR6 – 8:53

Development module:

Zoom in/out to 1:1 and back LR5.7 – 3-4 sec LR6 – 3-5 sec

Skipping between the photos: LR5.7 – fluently LR6 – “stutters” slightly

White Balance by “Pipette”: LR5.7 - <= 1 sec LR6 – 1-2 sec

Auto tone: LR5.7 - ~1 sec LR6 - ~2 sec

Erasing 10 dust particles with

healing brush (same photo): LR5.7 – 14 sec LR6 – 20 sec

Though the last test is also depending on my ”user speed” it shows the

general impression. I need to wait until LR6 allows me to continue with

the next procedure like using the healing brush again for the next dust particle.

Some time difference might be academic if it is just 1 sec but it sums up over

the time and my work speed is reduced.

Graphics card:

I am using an AMD Fire Pro W5100 Graphic card for Workstations. Details you will find here:

http://www.amd.com/en-us/products/graphics/workstation/firepro-3d/5100#

The resolution of my monitor (EIZO) is 2560 x 1440 pixels

CPU:

Intel I7-6700K with 4.0 GHz. Details are here:

http://ark.intel.com/products/88195/Intel-Core-i7-6700K-Processor-8M-Cache-up-to-4_20-GHz

btw: My testing period of LR 6 seems to expire today. I remember having usually 30 days test period

to check the functions of my former Adobe products. This time only 7 days….

Does the performance improve if you turn off the Graphics acceleration? (Go to preferences, click on the performance tab, then uncheck "Use Graphics Processor"?)
