i did a factory reset too, but:
some settings remained (packages, dropbox), the others were lost.
A factory reset erases a small flash partition, where most settings are stored. It doesn't touch the disk(s). The packages are stored on disk, and so survive a factory reset.
What speeds do you measure? What kind of network do you have?
i have simple 100mbps network, wireless G.
copy wired: at about 10mbps,
copy wireless at about 4 mbps
actually, there is a some improvement, earlier wireless copy was at about 2-2,5 mbps
how can i still improve the speed? (wireless mainly)
