I am in need of some help with a speed issue on a test Red Hat server. The server is running RHEL4 ES Update 4. When copying a file using FTP it transfers at 19GB per hour, but when copying via SMB it transfers at 3-4GB per hour. The network card on the server is Intel 10/100. When copying using samba a simple cp -av command is used. I have tested when this server is part of Active Directory and when not with the same results. Also, I've tested enabling and disabling selinux with the same results. Operating system: Red Hat Enterprise Linux ES release 4 (Nahant Update 4) Linux kernel: Linux 2.6.9-5.EL i686 Samba packages installed - samba-common-3.0.10-1.4E - samba-3.0.10-1.4E - system-config-samba-1.2.21-1 - samba-client-3.0.10-1.4E Samba configuration file [global] workgroup = ABC realm = ABC.LOCAL preferred master = no server string = Samba file server security = ADS encrypt passwords = yes log level = 3 log file = /var/log/samba/%m.log max log size = 50 winbind separator = + winbind use default domain = No printcap name = cups printing = cups idmap uid = 10000-20000 idmap gid = 10000-20000 winbind enum users = yes winbind enum groups = yes template homedir = /home/%U template shell = /bin/bash password server = dc.abc.local Samba mount command in startup script. mount -t cifs -o credentials=/etc/.samba_cred_backup_server,rw //webbackup.abc.local/backups /mnt/backups # cat /etc/.samba_cred_backup_server username=nasuser password=nasuser I would appreciate any ideas on this. Thanks. Phusion
