i have nas built 9.10 server on msi nettop 100 atom device 2 sata drives in raid1 array. installation done alpha release of karmic, alpha 5, think, , gradually updated using apt-get. i've setup samba shares on server , access shares vista clients.
experiencing situation writes nas reasonably fast, 50-60mb/s on gigabit lan. however, reading files nas capped @ 10-12mb/s. it's if reading nas limited 100mbps reason.
appreciated. here's lspci info nic card:
