I never got much benefit from jumbo frames either. With SMB2 in Windows 6, however, I always get >110MB/s if the disks on both sides can handle it. I was about to build a NAS solution using FreeNAS or OpenFiler with an older box and some spare drives (X2 4400+ and 9x 250GB WD PATA disks), but decided to wait until Samba supports SMB2. ZFS would be nice too...
