Why is lightroom so.. ssssslllllllllloooooooooooooowwwwwwwwwwwww

[contributor_M]

Seriously, this is getting ridiculous. Trying to edit a photo in the develop module, and the changes takes a couple of seconds to display and render and such.

I'm running a quad core machine with 4 gigs ram on Win 7.

What's the deal???

[rwwright]

nothing slow about my lightroom3. and one of my catalogs has 50,000 photos in it. i do have 9 gig ram but otherwise same. mostly d300 and d2x and s630 files. raw , psd and jpg from 630

I honestly don't know what it is mate. I get going and lightroom seems to slow down a lot. When I try another application, everything is preforming as it normally should. I really did notice this until after I got my Wacom bamboo tablet though.

[dlanter]

Have you got the latest updates installed with Lightroom? Not positive, but I seem to remember an update dealing with problems using tablets. Other than that, have you tried optimizing your catalog?

[rwwright]

also vote for optomizing catalog. in lr3 you can do it from file menu. i do this regularly.

I have the previews set to display as standard. Would adjusting my preview options have anything to do with it as well?, and if so, how would I change it?
Optomizing my catalog now.

it was slow for me right after I upgraded to 3.3

However, I did have multiple applications open and it had been a very long time since I rebooted my machine. Because after I closed everything down, and restarted the computer life is good again.

Good luck.

And for some time killing check this out.

Which version of Windows 7? LR is a memory hog and if you're using 32bit, I would suspect you're thrashing the memory.

[Rson]

tell me a little bit:

Specs on your system?
Version of LR and Win7?
how many images in your catalog?
file types in there (raw+jpg, RAW, JPG etc)


Aside from what was mentioned, I bet we can drill down more to tweek you out.

Check to see if your cache settings are appropriate.

I moved mine off the C: drive and increased the limit.

You have 4 gigs of ram, but that's not really all that much running Win 7 and Lightroom. Also, you didn't say the type--is it DDR2 or 3? Is Windows 7 a 32 or 64 GB?

What speed? I'm running LR 3.3 on Win 7 64, 8 GB DDR3 1600 mhz, and have no issues. How much RAM is free when LR is open?

This is a great desktop gadget to tell you how much RAM you have available at any given time; you may want to see if you're starved for more RAM. LR can eat lots of RAM, and the speed of the HDD that your catalogue resides on can really affect it, too. NEVER put it on an external USB drive unless you have a lot of time on your hands. Mine is on a SSD, so it's pretty snappy.

Ok. Here is my full PC specs:

OS: Windows Home 7 64 bit OS
CPU: Intel Core 2 Quad Q995 @ 2.83GHz
Memory: Corsair XMS2 PC2-6400 800Mhz 240-pin Dual Channel DDR2


Light Room version 3.3
Have a total of 14503 photos in my catalog.
They are a combination of Jpeg, RAW, and DNG files.

When LR3 is running, what does the info in your Task Manager (Performance Tab) and Resource Monitor show?
This is my Win7 Ultimate 64bit w/6GB running...
It barely blips the system.
The 1st spike in the CPU is me launching LR3.3 64Bit with a catalog that has 127K images in it.
The 2nd spike right behind it is launching CS4 64Bit to take the screen shot and paste the image below.

[contributor_M]

Ok. Here are some screenshots.

The first one, there was a major spike when LR3 launched. Afterwards, things seemed to calm down a bit.

Here are some bigger images of the two files.

I wonder if I can downgrade from Lightroom 3.3 since things started slowing down after I updated it.
