[Samba] samba slowness

[Javid Abdul-AJAVID1]

Hi 
User is complaining about slow ness 
they copy images ISO from unix storage to PC and then burn dvd and cds.
the typical size of each image is 600MB
they do it 4 to 5 at once

am running samba on solaris which acts gateway to nfs stored images.

i have no option of installing samba on local storage.

I appreciate your replies

its critical for them

what does samba do when we copy files from nfs to pc

thanks
