Hi everybody, I am using Samba with cups?on CentOS 5.5: 1, set up one network printer?by cups, it is created as a raw printer; 2, share this printer by Samba, using the below configuration in smb.conf [global] load printers = yes printing = cups printcap name = cups [printers] comment = All Printers path = /var/spool/samba browseable = no guest ok = yes writable = no printable = yes use client driver = Yes Samba users could print by this share printer. But one strange performance issue happened: The share directories in this Samba server are NFS share exported by one NAS(created by Openfiler). With this share printer,Samba users downloaded files from the share in this samba server very slowly, while uploading speed is normal; If I disabled this share printer(just comment the printer section in smb.conf), the download speed became normal. Any help, comment will be highly appreciated! Thanks in advance! Jian
