Lightroom Export Speed

DoubleCheese · 26 Jul 2017 at 20:07

This has probably been done to death, but I'm curios as to how much faster newer machines are to mine at Exporting High Res JPEG's from Lightroom?
My machine is an old, i7 2600K at stock speeds so 3.4Ghz but boosts to 4.2Ghz, 16GB DDR3 RAM, GTX 960GPU, Samsuns SSD and LR Catalogue and Pictures on a 3TB WD Black drive. OS is Windows 10.
I've just exported 735 files (mixture of D700 and D750 NEF RAW's) from it and it took almost exactly 80 minutes. I replicated it again and it was the same time. Export job is renaming the files and sharpening for screen.
CPU performance fluctuates between 75-100% and RAM is at about 8Gb use when exporting.
Anyone care to run a test and specs?

My PC is slow, i5 clocked at 4.4, 8gig ram, win 10.
Sure it's slower than it used to be at exporting. I always thought of upgrading but not sure if its wroth it, I just walk away for a while.

It's one of the few things in LR that will use all cores on exporting - im currently on an i7 haswell - I will let you know how much faster it is when I build my 1700 Ryzen.

PS: Also importing / rendering 1:1 for example + building smart previews will use all cores as well

Lightroom / Adobe Camera Raw can benefit from more than 4 cores.

Capture One does not benefit from more than 4 cores.

Just remembered I can't stream music and edit in lightroom. Anytime it does something it stutters the music as cpu is at 100% demand. That annoys me!

My system doesn't feel like a slouch, the OS is on a fast SSD. But, I've spoken to a few other photographers who've done the same test and they're getting export times from 40-45 minutes and some claiming 10-30 minutes. That makes my machine seem exceedingly slow!
I wonder whether the size of the LR Catalogue has something to do with it so I'm going to start a new LR Cat on a separate drive and try it again.

I started a new catalogue and it made no difference for me.

There are ways to limit the cpu/thread usage of an application, can't remember how though.

Didn't think of that, must do that!

It does however make proper use of a graphics card whilst editing and exporting. 50MP jpegs export from raws at more than 1 per second on my machine. Inexcusable that Lightroom is so slow to implement this.
