Since AE currently is using the essentially the same render pipe for RAM preview and final renders (unless you are playing with quality settings, resolution, etc. it should be relatively the same, storage subsystem bottleneck-factor notwithstanding. 

The way I’m set up, with a dedicated SSD just doing Global Performance cache, I’m amazed at the performance I get, and if the previews were full rez, they dramatically improve final render times. But to your original point, I could see a RAM preview elapsed timer being semi-useful. Maybe even log it somewhere. 

I tend to configure MP off for RAM previews on most of the stuff I’m doing (background processes spooling up delay kills me), but on for final render. I think I was one of the loudest voices crying for that preference setting, and so glad it’s there!

Interesting. I am going to do some tests on RAM preview vs. render vs. MP. With a stopwatch. Are there certain effects that push RAM more than others? HDD / SDD more than others in order to isolate performance?

My guess is if you are running the same settings as the final render ram preview should be always be a little faster since it doesn't have to write to disk.  Now you also mention MP render. If ram preview is set to MP also then see above. If not then it goes back to the comp being rendered if it is faster or slower with MP than not

Is there any way one could think of automatically getting the time it takes to do a comp RAM preview, other than clicking a physical stopwatch? For example in the render queue it shows your render time, is there anything like that for RAM preview? recorded/logged internally? or in a debug window somehow? 

Maybe a better question is: does a RAM preview take the same time as an MP render? Should I take render queue time to be roughly equivalent to the RAM preview time at full resolution? Or is one faster than the other?
