Or, just try different software ;-)

There doesn't seem to be any "method to the madness" as far as LR4 performance is concerned.

Some users report it works great on lower spec hardware, and some users report that is' horrible on nicely spec'd state-of-the-art systems.  IOW, throwing faster hardware at it doesn't always work. 

IMO, with a modern Core i5 CPU (even if it's a dual core mobile model) with a discrete graphics chipset and 8GB of memory, a modern app like Lightroom should not have horrible performance with laggy response to sliders, etc.  But, that seems to be the way it behaves on some machines.

So, you may want to try different software and see if something else works better for you.

As Malch mentioned, a new LR5 Beta is out now.  So, you may want to give it a spin and see if it works any better for you.  Get it here:


Personally, I use Corel AfterShot Pro instead of Lightroom.   You can download a trial version of it that works for 30 days to see if you like it or not.


Here's a webinar that goes into many of it's features that I'd suggest watching so you can get a better idea of what to look for when using it (as it's very full featured software):


It's very fast, with versions available for Linux, Windows and OS X (and scales very nicely as more CPU cores are available).
