[Samba] speed of samba vs Windows

[Todor Fassl]

Is there any reason to believe that a samba server would be slower when 
serving up roaming profiles than a real Windows server? I know roaming 
profiles are slow by nature and that there are things you can do to help 
like configuring ffolder redirection. But all else being equal, how would a 
samba server compare to a Windows server when it comes to speed specifically 
with respect to roaming profiles?

Our Windows guy insists samba is slow but I don't believe it.  He claims 
that when you load a roamng profile, Windows downloads only files that have 
changed and samba downloads everything. But he doesn't know anything about 
samba and I don't know where he got that from.
