Then I disabled shadows and soft shadows in all lights. (this scene does not appear to need them)
This caused export times to fall drastically going from an hour to a few seconds.
Render times dropped drastically as well
to roughly 6h50min.With those changes made, may I suggest using 02b Low_AA2 found in the Advanced>Alternative_AA render settings? Fast for so many lights but with good quality AA. (unfortunately the AA part takes a long time, about half, as it's not multi-threaded, nothing we can do about this but it's much faster than Easy 07)
Will render much more quickly if you eliminate specular reflection on the floor. Calculating the blurry reflection on so many lights and LEMS is causing long render times, but benefit seems
The "perfect reflection: Low" template on the floor could be interesting and render much more quickly.see attached - version without Denoise and one version with Denoise
modified file is attached for your convenience, if you wish to take a look.
