Sometimes I wonder when I see people complain about new machines if maybe the speed hits their seeing has to do with Spotlight indexing the drive for the first time? My new MBP is in the mail, but I installed Mavericks on my 2010 17" i7 MBP and I was disappointed the first 10 mins at how sluggish it was... until I saw "all" my resources going to the indexing of my HDD (non-SSD).
