Performance weird problem

[Hdiab]

hello,
first of all, thx for this magical render engine.

im rendering a scene that containe lots (about 500,000 or more)  of particles with hdr lighting and direct corona lights, the particles have a gold material and a glass globe and white reflective floor.

the wierd thing is that m rendering on multiple workstations with diferent specs.

WS 1 Specs:
Cpu: core i7 3960X 3.3ghz 6core with HT 15MB cache
Ram: 64GB DDR3 1333MHZ

WS 2 Specs:
Cpu: Core i7 980 3.3ghz 6Core with HT  12 MB cache
RAM: 12GB DDR3 1066MHZ

WS 3 Specs
CPU: 2 * Xeon X5650 2.66GHz 6core each with HT 12MB cache
RAM: 8GB DDR3 1066MHZ

the problem that WS2 render the scenes Faster
WS1: 19:20  20 pass
WS2: 14:38 20 pass
WS3: 18:14 20 pass

so what is wrong????

So No one Have Any Idea of what is Happening...?????!!!

Could be lot of reasons.

You're asking why older 980X renders faster than much newer 3960X, correct ?

Are you rendering the same scenes from network ? Do all workstation have equal access ? Any possible bottleneck ?
Same Corona version and 3dsMax(service pack,etc.. version ?

Running syntetic benchmarks like Passmark or Cinebench reveal the same issue ? Other renderers ? Or is it just Corona ?
If it's only Corona, can you replicate it using the Corona Benchmark A4 scene ?

You first have to do some work yourself before asking others for clairvoyant skills.

thanks for your reply Juraj_Talcik.

yes equal access, same corona version, same max version, same scene.
and its just corona, the newer workstation work much faster in all other tasks.
I didn't test corona's benchmark scene but I will.

Could you post screens or renders of that scene? This might help.

This "gold material and a glass globe and white reflective floor" part sounds particularly interesting. :)
