Time taken is dependant on many things: the geometry in the scene, the materials and shaders use, the lighting, the render engine used, and so on. That is leaving aside the hardware- which looks to be not bad at all. If you are using Iray from with Daz Studio be sure, first off, you can, and are, usin the 1080 gfx card. I've not done much testing of late but I'd be inclined to just use GPU to start with. Ensure your scene fits within the VRAM of the gfx card (check the log file - Help> Troublshooting> View log file) or use a monitor program such as MSI Afterburner to see the utilisation. In fact, I'd recommend getting that anyway as it allows you to set up a profile for the fan on the card so you can be sure it's not throttling back for thermal reasons. Ensure theer is enough light as Iray does seem to like having a lot of light to enable it to 'converge'. Be wary of relfective surfaces as they drive up render time.
Start small and slowly build up the scene and see if there's something specific that suddenly gives a big hit on render time, then investiagate ways of mitigating that.
Well i have take the info from log file about the geometry and i take this :

It's too many things ?
And another question that can be helpfull for me... I need an answer at this too... ! if the scene is an an station train with many characters there... but the viewport take only an angle and 2 character.... the others things can alter the processing even if they don't are in viewport ? i mean like other things and character... or its better delete everything that is not in viewport and leave only what i need ?
