Title: A PC Optimized For LR.

  This was on DPR today and it seems to be of general interest so...

in addition this article

http://appleinsider.com/articles/18/01/20/video-apples-imac-pro-vs-2013-mac-pro---photo-editing-comparison-part-2


Apple insider would like to see that the iMac pro is faster than the MS machine of 1600$, but it is not in many cases.
sometimes it is even 50% slower

It all has to do with the software;
LR is not optimized to uses many cores nor is optimized for GPU...
A bit sad for relative new made software.

That is why a 2018 imac will be faster than the imac pro- the CPU corespeed is still most important.
this person has overclocked the a 6 core cpu to 5.2GHZ - the imac pro reaches 4.2 GHZ ( and could do 4.5GHZ if Apple let it)

I sometimes run mulitple versions of photoshop - the only way to let photoshop uses 8 cores is to run 4-8 photoshops... (!)
Depressing really - CC is like CS6 in this respect.

I am puzzled by some things in this thread. I run Windows 7 on an 8-year old Dell with an i7 CPU at 2.9 GHz, with SSDs and tons of RAM. I am using LR and PS CC. Things in the develop module just seem to happen instantaneously. Imports can take a while, even over USB3, same with exports, but in general the program never keeps me waiting. And, with Task Manager open, I see that 6-8 cores are involved in the things I do.

The same is true of PS CC. I just checked by running a few tasks such as a bicubic upres and see that PS is using at least 6 cores.

Yes, I saw it yesterday, as the author mentions he uses the machine for other things. If your interest it is pure Lightroom you could save money on the GPU and memory.

Also, for noise I will prefer other cases, a Factral Define R6 or BeQuiet Dark Base 700. And I don’t like the pump noise of the AIO cooling systems, I will prefer better a Noctua DH-15 cooler. Yes, all that will make a more bulkie case.

Adobe performance is just abysmal and I have no words the describe it. The latest LR performance is terrible, despite their claims of major improvement or engine rework.

Just look at their premiere pro.

an 8-year old Dell with an i7 CPU ... I see that 6-8 cores

how did you manage to put 8 core i7 CPU in 8-years old Dell ? did you replace the motherboard ? the first 8 core i7 appeared in 2014 with socket LGA 2011-3 ... just curious

Probably mixed physical and virtual cores together.

Beats me. I did not replace the MB or anything like that. FWIW, the I7 CPU I have, 2.93 GHz, is actually 4 physical cores that are emulated as 8.

That is an absurd statement. Many people are using Adobe software without major issues. That said, I have the impression that LR seems to exhibit a wider range of performance differences among users than most other major photo processing software. My experience with Lightroom has varied considerably over the years, but this could very well have had as much, or more, to do with the particular computer I was using as it did with any problems with the program itself. Photoshop has largely worked very well for me over the years, starting with CS4. However, I have never used ACR, since I have always relied on Lightroom for RAW processing.

LR shoddy performance is common knowledge and even adobe admit it themselves, after massive backlash from users that are switching to Capture One - https://petapixel.com/2017/07/11/adobe-admits-lightroom-slow-says-speeding-top-priority/

As for Photoshop and the like, the core utilization is still very limited and prioritizes Mhz vs multi-threading.

Any attempt to review performance that just looks at core utilisation, is pointless.  Real performance depends on CPU utilisation, memory management, storage access, and application efficiency and all of that can be affected by whatever else the user has running or is doing with their system at the time.

Anyone who has used Lr for any length of time has encountered situations in which the performance drops, and situations in which the performance reaches unacceptable levels.  It happens.  Adobe recently (middle of last year-ish) focussed on addressing this.  Basically, the functionality had been prioritised over performance in the real world.  Improvements have already been made, and I expect there will be more.  Anyone claiming it's overall poor is either using absurd, artificial benchmarks, or has a highly convoluted workflow, or has a poorly setup system, or a very low spec system, or they're just jumping on a bandwagon and don't have any real experience).

What counts is how it performs in a real world workflow that is itself reasonably optimised (convoluted workflows are their own worst enemy).

Maybe you can help me. Why is LR Classic CC (latest update) crawl when browsing through my photo collections? All I want is sort the photos by metadata such as camera model, lens, year etc. All photos (JPEG and RAWS from Canon DSLRS and Sony P&S) are stored on 4x800GB Flash ARRAYS in Raid 0 because i am trying to isolate the bottleneck. I even tried a RAM drive and its the same effect.

No idea. It is working fine with my current computer, a recent iMac, and it has also worked reasonably well with a 2012 Mac Mini.

How many files, how many directories?  My first suspect whenever a large file access goes dead slow on Windows is AV.  If you set an exclusion in your AV for the directory/ies in question, see if that makes a difference.  Typically, the heuristics in the AV see mass file access (and possibly modification) as suspicious behaviour and starts to monitor and check every single file as it gets touched, dragging access to a crawl.  I've not actually seen it happen with Lr, but since Lr doesn't do this on my system (Win 10) or David's (OS X) it makes sense to look at other factors.

Where is your catalogue stored?  How old is it?

There simply isn't faster than this... at a high cost. ;)

This gives us an idea of the price bracket Apple will be shooting for with the new Mac Pro.

That’s overkill even for 8k vídeo processing...

Most probably so.

Still, I was a bit disapointed by the impossibility to order the 48 cores version with 2x24GB GPUs... ;)

Sure? I was playing with the configurator: http://store.hp.com/us/en/ConfigureView?catalogId=10051&langId=-1&storeId=10151&urlLangId=&catEntryId=3074457345618619819&quantity=1 , for 67000 something dollars I was able to 2x28core Xeon processors + 2 x Nvidia P6000... well and 4xM.2 SSD 1TB drives... 1.5 TB or RAM... you know, the bare minimum to use Lightroom at a decent speed...

I think you need 2 of those and a Bentley SUV to carry them with you when you do a shoot.
