Speeding Up Lightroom 4
Mar 28, 2013

I originally posted this in the PC Talk forum, but it doesn't feel like many Pentax users go there, so I'll re-post it here.

If Lightroom 4 is too slow for you (like it was for me) maybe this will help.  I've moved Lightroom's Catalog and Cache to a RAM drive and it's made a world of difference.  That, combined with a couple workflow ideas, and version 4 is finally usable.  I'm aware that an SSD can do the same thing, but this way is free.

If this has been discussed before, my apologies.  If not, I've created a webpage describing exactly how to do it, including where to find a free RAM drive.

Hope this helps.  It sure has cut down on the number of potty words I've been known to mutter over this issue.

Ok, I read through the link and am intrigued, as I am currently thinking about this same issue of speed in Lightroom. Unfortunately they talk about RAM drives as if everyone and their mother knows as much about them as a video card. I have never even heard of a RAM drive and I am not all that far outside to loop of computer parts. So can you fill me in a little?

I see the Ramdisk is a virtual RAM drive? Are RAM drives all virtual? Are there portable one's for a laptop? Are you using this virtual one the guy is?

Then there's this little nugget;

That's all there is to it. If it sounds complicated, just take each step one at a time. It's not that bad! You need at least 8GB of RAM to do this. Nothing less will work.

Does he mean 8gb of RAM on you computer to begin with? If I had 8gb of ram to begin with, I wouldn't have any problem to begin with. I have a laptop with 4gb RAM and it's not upgradeable.

Ditto ....

That's why I use ACDSee Pro 6 .... it flies, and accepts DNG K-01 files, unlike C1 Pro 7

I think you are pretty far out of the loop if a ramdrive is a new concept to you.

http://en.wikipedia.org/wiki/RAM_drive

"The first software RAM drive for microcomputers was invented and written by Jerry Karlin in the UK in 1979/80."

I see the Ramdisk is a virtual RAM drive? Are RAM drives all virtual? Are there portable one's for a laptop? Are you using this virtual one the guy is?

There were a couple of products for PC computers that made a drive out ram that were on the market a while ago and I think now discontinued. They weren't very successful as they used smaller amounts of ram and cost a bit more than people were willing to pay in comparison to just buying more ram for the computer or just upgrading the computer to newer hardware that could use more ram. Gigabyte iRam was one. It was a PCI or PCI-e board with slots for up to 4Gb There was another more drive looking product on the market that was had SATA connectivity, also a battery, but with SSD coming to market, I think both products only had a short year or two on the market.

Does he mean 8gb of RAM on you computer to begin with? If I had 8gb of ram to begin with, I wouldn't have any problem to begin with. I have a laptop with 4gb RAM and it's not upgradeable.

With 4Gb of ram you can probably create a ramdrive of 1Gb without issue. About the only time this makes sense is when using a 32bit OS were the OS can only really use 3Gb of memory. The idea is to place the ramdrive into the ram space the OS can't address thus not impact the ram available to running programs.

Thank you
Russell

Always been a problem with Lightroom. The way they've chosen to implement and write that programme is weird. Can anyone tell me if there is any great difference in the usability, accuracy or feature set between the cataloguing in ACDSee Pro and Lightroom? Because ACDSee Pro is very fast. Moving between editing and managing files (or using the RAW "develop" mode) is seamless in ACDSee. Lightroom has always run like a dog. I haven't tried Lightroom 4 and I'm just about to, so I suppose I'll find out soon enough. The price of SSD's now makes that a very affordable option.

It is not free

You need to have enough otherwise unused RAM on your system and last time I looked RAM wasn't free. Add in the susceptability of volatile RAM to glitches and an SSD is a better bet all round.

As I stated on my webpage write up, you need at least 8GB of RAM in your system to make the RAM drive viable.  If you meet that requirement, then the RAM is indeed FREE to be used by whatever resource claims it.  I've never had Lightroom (plus all other resources) exceed 4GB, even after 8 hours of processing near a thousand pictures.  In fact, it normally levels out around 2GB.  Windows has the uncanny ability to function differently from computer to computer, so maybe your experience is different.

My original post acknowledges the SSD.  Maybe a new thread could be started about them.  This thread is about setting up and using a FREE RAM drive that greatly speeds up Lightroom 4.

Substitution of fast RAM for slow hard drives is not new.  I remember using a 160K RAM drive on an old IBM XT with 640K of memory to hold a DOS file (Command.com) that was referenced regularly.  Even though everything has become bigger and faster this substitution technique should work.  That said, there is "no free lunch", and assigning memory to a RAM drive removes that same memory from Windows or whatever operating system is in use.  That may have consequences for other parts of the program - or other programs if the machine is multi-tasking.

I upgraded from LR3 around Christmas, after I upgraded to a new computer.  It's so much faster than the old one that I didn't realize LR4 is slow.
