Quote - > Quote - Ok Trying what you suggested , I am going simple i am attempting to render some mugs that i converted from max 2012 to Poser 

at the moment lux render is giving me these stats on my system

the time then

threads 4 gpu's 4 - 41.51

S/Ps 37.53

ks/s 741.06

this is followed by KC/s 1945% and then eff 9% Geff

Okay demon.. looks like you posted the stats on the status bar.  I can give you an easy idea of what they mean.  "threads 4 gpu's 4" means lux sees that you're using a quad-core processor and a quad-gpu video card.  this essentially means nothing unless your processor(s) are buggered up and you've dropped a core.  "41.51 S/Ps"
means that your luxrender has processed 41.51 passes over your entire render.   "37.53 ks/s" is the speed that you're rendering at.. as in it's sampling 37520 pixels per second.  I'll skip the next for a second.. the 1945% efficiency and 9%Geff how efficiently luxrender is processing and finding your lights.  1945% effeciency is pretty good for someone using Reality for the first time.  The Kc/s is your samples per second multiplied by your efficiency.  This is the total number of light samples per second that luxrender is processing.  Since it's all about the lighting, the higher your efficiency the faster your render will clear up.  These, I've learned are truly the key stats.  You want lux to be able to easily process your lights(efficiency).  The samples/sec is primarily dependant on materials and the geometry of the items in your scene.

Place a simple nude figure with just hair into a cube with a single mesh light and you can see that efficiency jump to 4000% or better.  And your scene will clear up in a couple hours.

Render speed with Luxrender depends on several things(Paolo can correct me on this).  The gloss settings of your materials(high gloss slows things down) the amount of glass or water in your scene(will slow you down too), the number of lights you have in your scene, your materials/textures, and the total amount of figure geometry that lux has to process.

My advice is for a few renders.. keep it simple.  If you're rendering people, do one person either a nude or dressed in simple clothing, a single mesh light(use posers lights to light your scene while you're working on it so that you can easily position and aim your mesh light and then disable all but your mesh light in reality) maybe a simple background, and then enclose them all in the included posing cube.  Make sure that you scale the cube up enough to COMPLETELY enclose your lights.  If not it'll seriously gimp your render speed too.  Make a couple or more renders that way, then slowly add more ambitious/complicated objects into your scenes.  In no time you'll know how lux is going to react to various elements being added to your scenes.
