LR hungry!!!

before i was using a C2Dual and thought it was slow cuz of that. now i'm using a quad-core CPU and i still feel LR3 is resource hungry!

it really lags down my computer and don't know what to do.

is there another program i can use, or should i just go back to using BR + PS4 combo?

Well, two things that LR "needs" is a good amount of RAM and a good amount of free hard drive space (which makes having an internal "data" drive a good thing). Also, the Cache Lightroom shares with Camera Raw in CSx is by default quite small. In the Lightroom Edit/Preferences there are preferences for how LR handles previews that you want to review; in Bridge you can resize the Camera Raw cache using Edit/Camera Raw preferences as well. Typically you want to set it to anywhere from 5 - 20 GB.

Probably due to lack of RAM. How much do you have?

Good news is that's *usually* an easy fix.

I've got a quad-core in my laptop along with 4GB ram and LR3 doesn't feel slow at all to me.

Runs very well on my machine. AMD 6-core 2.8ghz w/ 8gigs of RAM. I'm always a proponent of increasting RAM.

LR 3 runs well on my D/Core 3.2, 8GB Ram, set with 200GB scratch disk and 200GB for Cache on Ex/Drive, and windows 7 64Bit..

no issues running LR on new Mac book air 2.13GHZ 4GB RAM and 256 SSD drive.

LR3 runs just fine on my MacBook (13" white) with 4GB of RAM. Of course, 64-bit version makes memory issues go away...

I have a year 2008 dual processor quad core Mac Tower and it was dog slow with LR3 until I upgraded my RAM. I am now running 10gb of RAM and LR has been reborn.

sorry for the late reply.. been stuck in canada airport for quite some times.

i have a quad-core with 4GB of memory (which is maxed out) and the rest are all SATA drives and what not.

Looks like if i were to keep using LR, i'll need to get a new system.. hehe..

I'm assuming Windows (I know nothing about Mac OS's) But you will benefit from more RAM (total of 6 or 8 Gb), but to do this you will need a 64bit OS to access more than around 3.5 Gb.

I have a Core 2 Duo E6750 (2.67GHz) box that only has DDR2 800 Memory. I had 32 bit Windows 7 with 2Gb of RAM and it struggled with LR3/CS5.
I changed to 64bit Windows 7 and installed 6Gb RAM and it's a lot (lot) quicker now.
