Adobe wants feedback on Lr performance

On Lightroom Performance

I would like to address concerns recently voiced by our community of customers around Lightroom performance, as improving performance is our current top priority. We have a history, starting with our first public beta, of working with our customers to address workflow and feature needs, and we’d like to take that same approach regarding your performance concerns. We already understand many of the current pain points around GPU, import performance, certain editing tasks and review workflows and are investing heavily in improving those areas. Over the past year we’ve added numerous enhancements to address your performance concerns but we understand we will have a lot of work to do to meet your expectations. If you have feedback or would like to work with the Lightroom team on your most pressing issues, please fill out this survey. https://www.****com …QJDZgcb8YOEWSQZ​0k_2Fy4_3D

Is this legit? What kind of link is ****com

Very best,

I tried to copy the text from the Lightroom blog and the link did not follow. I tried to put in the link separately. So just go to the top link to the Adobe Lightroom blog and follow their link to their survey.

"On Lightroom Performance ..."

Seems to be legit.

That is so insulting. and disappointing.

Either Adobe has yet to begin exploring optimizations to LR or (here's hoping) they've been doing so and this is a strange way of managing customer expectations.

like reading tea-leaves from the Federal Reserve about banking rates.

It's not unusual for new computer systems to have software incompatibilities with certain programs. The link has a complaint from a recent iMac buyer. A larger community of LR users and recent iMac buyers should mean that performance issues are going to be resolved.

Pretty simple to me, increase multi-thread performance significantly to take advantage of 8+ core CPUs, and/or dramatically allow GPU performance to greatly out pace a single high frequency CPU core.

Very best,

With High Sierra supporting eGPUs, Lr not fully taking advantage of every GPU cycle will make Adobe CC more and more vulnerable to replacement.

As multithreaded processors and multi-core chips become the norm, architects and designers of digital systems need to understand their respective attributes, advantages and disadvantages. Both multithreading and multi-core approaches exploit concurrency in a computational workload. Multi-processor, or multi-core, systems exploit concurrency to spread work around a system. As many software tasks can be running at the same time as there are processors in the system. Multi-core systems and multithreaded cores have the common requirement that concurrency in the workload be expressed explicitly by a software program. Monolithic, single-threaded applications need to be reworked and decomposed either into sub-programs or explicit software threads; this work must be done for both multithreaded and multi-core systems. Whether or not a given software program can benefit from of the multicore and multithreaded processers more commonly found in our computers theses days has to be studied, to determine what latencies would be diminished by multicore or multithreading parallelism.

A very difficult process. low hanging fruit is batch processing.

Sorry about that. s u r v e y m o n k e y is in our bad words list, perhaps it was used in some other form is spam earlier.

Problem with modern coding is that they (need to) use frameworks so they can code for Win and Mac at the same time. That means compromises are needed in optimization.

They really should build and release a free "LR benchmark", and that would report them hardware/OS config with bottleneck info. Questionnaires do not help here.

Geekbench is a start (http://geekbench.com)​:

Seeing this I thought I would try my last years model, 2016 Dell XPS 8900 with i7 6700 @ 3.39 GHz, 16 GB 1065 MHz RAM, GTX 960 2GB and an unknown M2 256 GB SSD coupled with a 2TB HHD.

Single Core: 4780
Multi Core: 16258
OpenCL: 76690

What this doesn't take into account, and the reason I run a GTX 960, instead of the onboard graphics, is that I also use the Dell Ultrasharp UP2715K running at 5K resolution. Adobe support for the HiDPI monitors, especially this Dell seems to be not that great. Although running with GPU acceleration is actually supposed to help with HiDPI, it is generally less stable than running with it disabled. I also try to keep up to date with all the latest video drivers via the Nvidia app. One consequence of running the 5K display is that when viewing images older 6 & 8 MP images in Lr is that the 1:1 view doesn't actually fill the available screen real estate, even with all the toolbars etc visible. So I guess I am dealing with a lot of 1:1 previews for those images. On this screen viewing images at 1:1 is actually far more like viewing at 2:1 on a standard monitor, but sharper. It just seems like Lr is not as good at pushing around all those pixels as it could be. Having an Lr benchmark that took the 5K display into account would actually be very useful.
