Thanks Volker, I've Changed the values as you suggested, i noticed that 
the default value for max xmit is much less 16384! Still I feel like the 
performance is very slow indeed. This because on server, a can make 
copys arround 8gb/s! and in samba is all so slow and it freezes as i sad 
many times...

Can you have a second look to the log, to see if you see anything 
strange? I'm putting a dump off the level 1 log, for you to check, i 
know it's more general, but if you notice anything, then i will increase 
it to see it better!
