need help investigating slow Linux home LAN

Why are file transfers between PCs on my home network so slow when I can download stuff from the internet way faster? I'm a developer, not an IT guy; I don't even know where to start looking to figure this stuff out. Details below -

My home network consists of one Ubuntu 12.10 laptop and one Ubuntu 12.04 HTPC/file server/etc. The laptop connects to my LAN over 802.11n, and the PC over GigE. The router is an Asus RT-N66U. I have no problems accessing the internet from either machine; download speeds are fine on both according to speedtest.net . The problem is that it is agonizingly slow to access the PC from the laptop.
I've got the PC set up to export a directory over CIFS, so I can mount it on the laptop and get to my music and photos. Reading from or writing to this directory takes ages. It takes ten seconds to list the contents of a directory from a command line, and it takes 5-6 seconds to open a ~4MB image in GIMP. I suspect I've got smbd configured incorrectly, but then again I had the same problems when I had everything set up using NFS, but then again I might have set that up incorrectly too. This isn't a new problem for me, so I don't think it's the result of any recent software updates.
Any ideas on where to start digging? thanks!
