Well, I think I have solved the sluggish of Maverick's finder.
From the internet, what I did was to go to Finder's Action button > View Option and deselect 'show icon preview'. Then click 'Use as Defaults'.
It is now as quick as it was in Snow Leopard!
Good.Thanks for this. I thought I was crazy thinking this was an issue. Figured it was just my MBP acting up and being a nuisance. It mildly annoyed me for awhile but I found this thread and now it's like new! Excellent.
