Need help with my EFI folder and kexts to resolve slow boot.

I need help from someone who can give me a little more insight on the issues being created by my EFI folder. More specifically my kexts which I believe to be the culprit of my slow boot timing (1 - 1.5 minutes).

My specs:

  • Mac OS Sierra 10.12.6 (16G1917)
  • Asrock H61M-DGS Rev. V.2
  • x2 - Kingston 1333 KVR13N9S8/4 4GB DDR3 Memory
  • GeForce GTX 750 GPU
  • 1 TB Seagate HDD (Boot Disk)
  • 500 GB Seagate HDD (Time Machine)

The kexts that I currently have installed are as follows:

  • RealtekRTL8111.kext
  • RTCMemoryFixup.kext
  • USBInjectAll.kext
  • VirtualSMC.kext
  • VoodooHDA.kext
  • VoodooPS2Controller.kext
  • WhateverGreen.kext

They are all installed in /EFI/CLOVER/kexts/Other.

When I boot past Clover, I get the Apple logo and progress bar. At about 2/3 of the way, boot speed drastically slows down and the progress bar progresses only millimeters within minutes. Then, after about another minute to minute and a half, the screen sputters to black then back to the progress bar which just zips along to 100% and login.

Any ideas or help about the possibilities of what could be going on would be appreciated.
