Ok I realize that permalinks effect speed. This is what I figured out so far about the structures in terms of quickness and seo friendliness.
Default: The fastest but not seo friendly
Post Name: Most seo efficient slowest
Post Name, Category: A little less seo but better than default but it is the slowest
Are the items listed above correct?
Here is my second question can a default website rank well against the other two options or will it have to work 3-4X harder to get half of the successful rankings as post name or post name with category setup?
