I have a little more information now. (Thanks to the current thread on this
list 'Best way to measure disk bandwidth usage')
I started a large copy from the samba share to the local drive and then
checked ps and top.
ps lists the status as D+ (short term, uninterruptible wait, in foreground?)
top, after I push 'm' lists the state as 90wrq (samba waiting?)
so it seems to me that either something is wrong with samba, or something is
wrong with windows or I don't have enough experience to find the real answer.
Just because the second option is obviously true, doesn't mean options 1 and 3
so, how do I go about checking samba (I can't find a /var/log/samba, or
anything close to that.) and can anybody suggest anything else to try?
