I have Samba 2.2 running on a SCO UNIX 5.0.7 My Problem: The file transfer performance is slow and gets worse as more users log in. At times, if two users open the same file at the same time they may get hang. AS follows is the configuration of the smb.conf file Any help will be greatly appreciated.
