PC configuration for a "responsive" LR 4

What PC configuration is required to get a "responsive" & usable LR4 experience??
I'm want to upgrade my Intel Core2 Duo,3G RAM 32-bit, Windows Vista system on which it just crawls. However looking at this post it seems LR4 is appalling even on high-end i7,16GB RAM systems. ( http://forums.adobe.com/message/42484... )

Note: Yes, I've gone through the Adobe official Lightroom performance tuning article.

No, you missed out the word "some". Part of the frustration is that there's no clear pattern. I'm one of the many with an i7 based systems who hasn't seen a hint of these slowdowns.

-- "Part of the frustration is that there's no clear pattern" : This is true as I've read around in forums. And Adobe doesn't seem to have come out with any response either on this erratic experience.

Again, you should know that is not true.... 4.1 reduced the number of affected users, 4.2 did much more.

Have you determined what you mean by "responsive"? You need to find a symptom and work backwards from that to determine where the bottleneck might be. There are lots of threads here to help you with that.

For example, are you have issues in preview rendering in Develop? Or is it problems with slow sliders?

Because some problems will not be solved by moving to newer 64-bit hardware, and yet others will magically be resolved if you move your catalog over and recreate the previews and the raw cache. In the latter case it may have little to do with the new hardware.

Thanks for your reply John.

Previews is fine as I will generate 1:1 before going to Develop.

By responsive, I mean minimal lag in slider adjustments.

Once I have a decent i5 2500K, 16GB system on Win 7/8, and I also know the exact symptom, i.e Slider adjustments take seconds to reflect,then are there any proven solutions available from Adobe to fix it?

Abnormal Lr4 performance has to do with your config:

* OS/apps installed in which order.
* health and characteristics of hardware attached / drivers.
* services running
* data files that have gone south
* combination of features and options you use
* etc.

NOT the base hardware specs - usually anyway...

My recommendation: buy whatever computer suits your fancy, and build it lean & mean - test Lr4 on it *before* adding bells & whistles...

(consider building/re-building from scratch, if you are like me, and don't trust pre-configured computers...)

If it doesn't work well on a fresh new setup, you haven't got a chance with it fully loaded...

PS - don't have your hopes set too high - Lr4/PV2012 is generally slower than Lr3/PV2010, even in the best of circumstances.

Lr4 has also had some performance improvements (over Lr3) which are mostly understated due to the "other stuff"...

Cheers,
Rob

I will be building from scratch, I'm on budget(thinking of AMD FX 6100 :-P), but willing to stretch to a Intel i5 2500K if it will make any difference with LR4 performance. But it doesn't seem to be a problem with H/W spec as you said.

Yes PV2012 is where things slow down drastically. Having Lightroom will be practically useless if it is going to slow down the workflow, with no way to determine exact cause and fix it.

Sounds good. *iff* Lr4 is performing normally, then the faster the hardware the faster the software (limited by bottlenecks). But quality raw conversion is very demanding, and Lightroom employs only primitive data caching to support fast-loading for develop (usually raw data is converted almost from scratch each visit).

Note: Some people have devised workflows which gets the raw conversion done "once" ***, then work on the RGB files from there on out. For example, if you convert all your raw files to TIF after baseline post-processing, then further development in develop module is much faster. call it "manual caching" if you will.

*** You can always go back and redo the baseline processing baked into the tifs.

I'm hoping Lr5 will support an automated version of some caching like this, not unlike the jpeg previews for library module. maybe "tif previews for develop module" or something...
