    even if I create the 1:1 previews it takes around 3 sec. in the develop module for the picture to “load”. I already have a fast computer Quad core, 4 GB ram and HDD’s with around 100 MB/s. What exactly is going on when LR shows me “loading” in the development module? If the 1:1 preview is already rendered there is no reason to touch the RAW file and loading the preview with no adjustments shouldn’t take so long, am I wrong?

    Me too Andreas. No reason for this machine to work so slow as it does under LR Develop module. Simply unusable for my high volume needs. I’ve tried everything including 13Gb Ram, 275mb/s SSD drives, Quad core processor, etc. No Luck, no clue why…

    Add me to the list. Brand new AMD X6 1090T, 16GB RAM, 7200rpm SATA II drives, and it’s still slow, slow, slow.

    Re-rendering the previews at 1680 pixels does seem to help a bit, however, at least in Library.

    OMG, I feel your guys pain, I thought I was the only one. I’ve just invested $6000 in a new canon 5D mkII with L series lens for wedding photography and I find I can only edit around 15-20 full RAW images at a time before LR slows to ant pace. 20 secs between actions and mouse clicks. SOOOOOOO FRUSTRATING!!!! I’m starting to miss client deadlines. Was gonna invest in more ram for my laptop but if you’re having trouble with 13GB or even 16GB of RAM I won’t even bother. Dumb.

  5. Sean says:

    Hey Luke, How much RAM do you have now? The reason I ask is that my computer is never as slow as you’re claiming. RAM does help. More importantly is a fast hard drive. You might also want to invest in a 500GB Western Digital Scorpio Black 7200rpm drive as well. If you’ve already dropped $6000 on camera equipment that makes 20MB+ files, you’re going to need to invest in your computer no matter what software you run.

    Thanks Sean, yeah I’ve Googled the crap out of this issue and I realise that Epic amounts of RAM are needed. I have 2010 model HP pavilion (I know, I know, not the greatest of hardware but the specs are pretty good: 640GB hard drive with 6GB of DDR3 RAM with an i5 processor. Pretty good for a laptop. Anyway, removed around 70% of my current LR catalogue and makes no difference. Don’t know if this helps but I changed the LR cache from 1GB to 30GB it seemed to go a lot faster after shutting it down and restarting again. Having said that, I was only editing a small number of images and it’s speed is passable with low workload volumes. Thoughts?

  7. Luke says:

    Btw the $6000 price tag is in New Zealand dollars. Just in case you had heart attack over 5D prices :)

    Luke, your bottleneck is most likely your laptop hard drive. Laptops usually use the slow 5200 RPM hard drives (saves on battery and heat). Each large RAW file has to be located then read off that slow hard drive whenever you go develop a new photo.

    If you’ve spent this much on equipment, you may want to look into a desktop with at least a high end 7200 RPM drive with a large cache. Also consider a SSD (solid state) hard drive for the desktop, which you could copy your current set of photos to before starting work on them in lightroom.

    Also make sure your hard drive isn’t in use in some other background program, such as a virus scan or windows indexing or file sharing. Trying to do two things at once will slow a hard drive down exponentially.

  9. Luke says:

    Yeah I’m very particular about not having background programs running. I always close everything before opening LR. I’m not sure what the hard drive speed is and I hadn’t thought it would make the difference needed. In any case, the laptop’s off to the shop tomorrow to get 2GB more RAM and if that doesn’t help then I’ll look into a desktop. Any suggestions for a consumer? I’d have no idea what to buy. Best manufacturers if I decided to have one made to spec?

  10. Sean says:

    I wouldn’t put too much faith in going from 6GB to 8GB RAM. In fact, you should save your money, especially if you’re having a shop do the work. It’s not going to make that much difference if you’re not multi-tasking much.

    As Albright mentioned, the hard drive is way more likely causing the bottleneck. You can get a faster drive for a laptop (like one mentioned in my earlier post or an SSD like the OCZ Vertex 2 or Vertex 3) but if you’re not needing the portability, I’d recommend a desktop. It’s the route I eventually took and I don’t regret it at all. Get a tablet for mobile computing and a solid screamer desktop for real work.

    I have an SSD for my main boot drive and three 2TB hard drives in RAID 0 for my media (well backed up of course). This is where I saw the greatest improvement in speed, not processor or RAM.

    Despite everything I’ve done, Lightroom is still a bit of a dog. They really need to optimize their code.

  11. Luke says:

    Thanks Sean/Albright, appreciate the tips, I’ll check with the guys tomorrow about upgrading the hard drive to faster one. Crazy times.

  12. Luke says:

    Hey fellas, update on the new RAM, works better than expected. LR only lags ever so slightly after a while now. I was able to edit a whole crapload of my sister’s wedding photos shot with a 1D mkIV on full RAW. Much relief. Also enquired about getting a 7200 drive put in and was pleasantly surprised at the lowish cost. Might head down that road soon or take the plunge and build a desktop. Thanks guys! Appreciate all your input.
