I tried “Preview” before submitting a long post and could not find a way to edit the post further, in so doing lost the post – out of time to type it all again now.
So without explanations, my recomendation for anyone experiencing what they feel are excessive boot delays are to try a partition size of 25Gb (25 x 1024 = 25600) using one of the methods previously discussed in this thread. That may be the largest cache size you can use to reduced this problem if you are experiencing it.
Regardless of partition size one uses, occasionally seeing the Windows logo for up to two revolutions of the dots is part of normal cache operation. Testing continues, I have two of these in different machines now now, one will remain at the original 29.xx Gb partition and one will vary.
