Use the trick above with "Fake emit" and cast shadow off. You should never do this for animations unless you are modeling and rendering a product shot of a light fixture itself. In the effort to model a realistic light, sometimes people put lights behind glass or a translucent surface. Avoid them, use clever "tricks" to "appear" like there are translucent materials - such as a "Fake emit" light emitting material on your lamp surface - turn off cast shadow for that, and any material you don't want or absolutely need to cast shadow.

Metal and Brushed metal, SSS, translucent, and some others tend to be slow to render. These will cause a slow down in rendering as the engine tries to compensate for the errors from the colors. Make sure no colors are purely saturated above 90% brightness/saturation because this is not physically possible. Any "pure black" surface should be no darker than 10% grey.

White or Black or fully saturated colors - Start with the assumption that any "Pure White" surface in your scene should be no brighter than 90% grey.

Bright lights - lights that are too bright will need "error correction" which takes the engine time and so be sure all lights are correctly powered - use "exposure" to correct the brightness of your image, instead of using brighter lights.

The soft shadow takes a lot of time to anti-alias. If soft shadow is not critical in the scene, disable all soft shadows for all lights to render much more quickly. Remember that the light radius only affects the softness of shadows, it isn't needed to make the light brighter. Be careful of your light radius and make sure it isn't colliding with geometry. Use Twilight V2>Diagnostic to find quickly all the texture sizes in your scene and so you can know which need to be reduced. Each ray which must be traced throughout the scene has to be checked against each texture pixel that it touches, so reducing this calculation is fast and simple. Use the lowest resolution you can for each texture that will still look good.

Usually we can go much smaller than we think, even down to 128 or 256 pixel images. While it's tempting to go big, you are killing your render time. A lot of models available for download have ridiculous enormous textures. If only camera is animated (it's a fly through animation), make sure your Animation method is set to Only View and that 'Reuse Lighting Information" is checked.If this is not possible, please try these tips: Or render parts of the animation on multiple machines. To reduce render times, first would be to get a much faster machine.
