I've also got Cat6 and coax wired throughout the home. Twenty drops total. I've got a decent-ish D-Link 24 port switch...
I've had mixed success with Jumbo Frames at home and at work. I actually abstain from using Jumbo Frames for iSCSI since I'm dealing with much smaller files, typically.
I see 80 on average at home with peaks from 90-125. Of course, part of that is Windows caching with Vista/7. Regardless, VERY nice setup, Rakeesh. I really like TRENDnet equipment - I've got a cheap Wireless N AP with from them.
