LIGHTROOM: Stop adding feature and just FIX the performance!

Optimize that LR5 and stop focusing on new goodies.. Still has no GPu acceleration and still need a freakin BEAST of an Overclocked cpu to be able to work decently in there without stupid lag when only navigating from one image to another in develop module.

Well, you are making an error assuming that feature development and core development are mutually exclusive. They are not, bit leaving that aside, you probably want to explain your pain-points more clearly.

I used very modest equipment, and Lr has always run reasonably well. There are always exceptions, of course, and consumer equipment differs widely. But there is no root cause for all perceived performance problems.

For example, GPU performance only affects a small part of the things Lr does, and most things are disc or memory bound, not CPU bound.

But, we can't know what your problem is until you describe it. Then we can work from the know to the unknown to work it out.

Maybe there us a problem. It is impossible to tell from this post specifically, and even the set of reports in an online forum are not good data points.

Here's my setup and more details

Dell U2711 (2560×1440)
Intel Core 2 Quad Processor Q9450 (12M Cache, 2.66 Ghz, 1333 Mhz FSB)
2 x OCZ Vertex 3 120GB ssd in raid (catalog, Win7 x64 and LR5 are on it and some recent pictures, all the rest is on my NAS)
XFX Radeon HD 6870 900M 1GB DDR5
8 GB DDR3 ram

I always have lag when switching from picture in develop mode, or while zooming or applying filters. Also all 4 cores always hit 100%. When I export lets say 200-300 pictures, all 4 cores are tapping 100% during 10minutes (or whatever the time it takes).

Also good to know that I work with DNG images.

Bottle neck here seems to be the CPU for sure.. but damn.. it’s really not that bad of a cpu how can it need more than that based on what they’re saying in recommended hardware.
