does tomatousb use jumboframes for the nas service provided via the USB interfaces (rt-n16 for example), if not , can it be done using a mod like toastman's, and would it help improve the low nas speed. the theory appears sound according to wikipedia. oh, and what size jumbo frames are supported?
Transfer speeds when using the router as NAS are limited by the rather tiny CPUs most routers have, not the size of ethernet frames. If you want need higher speeds check that the drives use ext3 as filesystem instead of ntfs, if you need even more speed you'll have to buy/build a dedicated NAS.
larger size ethernet frames decrease the processing load of a network transmission, which would in theory help on routers with weak CPUs. Ext3 is already being used, I am actually halfway down the path to trying jfs, just for kicks, as I have little confidence it will improve speeds beyond ext3.
In my experience, it doesn't help. As an occasional file dump, small media server for music, the router is great, but a NAS it ain't. But then, I am one of those people who think gigabyte LAN is slow :-|

So how can the wireless routers claim to work at 300Mb/s in wireless-N? I don't get much more than that with wired Gigabit Ethernet between fast laptop and fast server via an expensive gigabit switch - but at least it is about 4x the speed I used to get with 100Mb/s lan - maybe its limited by 300Mb/s SATA-II drives? Specs and marketing never match reality where wireless is concerned!
I believe marketing guys came from the car manufacturers. They will advertise top speed, and will never take road condition, traffic laws and traffic conditions into consideration.

Wireless speed has absolutely nothing to do with the NAS performance of an router.
