No idea if it's still valid, but I have always had mine set to zero since Win7 & Win8.1. I have it on 10 because I'm using the Macrium Reflect boot option, which is the same as dual booting(WinPE environment).
I have always had system recovery turned on with my SSDs as it's needed for Volume Shadow Copy Service(Shadow Copy - Wikipedia, the free encyclopedia)
The only things that slow my boot time is my 2nd internal HDD as it is multi partitioned.
I do use "Fast Startup"(Fast Startup - Turn On or Off in Windows 10 - Windows 10 Forums)
I don't have or use Crystal Benchmark, because, for me benchmarks mean nothing, sorry there.
As an SSD seek time is zero the problem has to be something else. You have more than enough RAM and an i7,
Have you tried clean booting? With you 3rd party AV turned off?
