Hi. I've run into a significant performance problem, where Samba shares are fine except for programs executed from the shares, which take about 100x longer to launch than expected.
Copying local Windows directories with large files to the Samba share is getting 30 Mbytes/second. However, trying to run programs from the same samba share is taking 30 seconds to 5 minutes to launch the application (compared to sub-second launch time from shares from Windows XP 64 Pro systems for the same programs). I'm trying to set up Samba 3.0.24 under Ubuntu 7.04 as WINS master workgroup (not domain) server, to share to a dozen systems running Windows XP Pro 64 SP2. Network switch is a Netgear 16 port Gigabit switch. The ADSL modem is acting as DCHP / DNS server for the network. For now firewalls are disabled on the Ubuntu server. Disabling firewalls on the XP Pro 64 clients is making no difference. I've tried many different things, and nothing seems to make any difference. I'm wondering if there is a SAMBA / XP 64 bit client problem, or if the problem is somehow related to the switch, because NBTSTAT is reporting a "MAC Address = 00-00-00-00-00-00" for the Samba server. I can't see any obvious problems. I can browse the samba server. The shares are visible and having no access problems. Other applications have no problem with UDP broadcasts working across the switch. The show-stopper problem is that application load time is horrible if an application is run from the Samba share (around 100x slower than it should be). The clients are standard XP Pro 64 with latest SP2 patches. They have no problem running applications from another XP Pro share. Any help or hints would be greatly appreciated. Output from nbtstat looks fine except for the MAC address: --------------------------- C:\>nbtstat -a snsix Local Area Connection 3: Node IpAddress: [10.1.1.7] Scope Id: [] NetBIOS Remote Machine Name Table Name Type Status --------------------------------------------- SNSIX <00> UNIQUE Registered SNSIX <03> UNIQUE Registered SNSIX <20> UNIQUE Registered ..__MSBROWSE__.<01> GROUP Registered SNS <1D> UNIQUE Registered SNS <1B> UNIQUE Registered SNS <1E> GROUP Registered SNS <00> GROUP Registered MAC Address = 00-00-00-00-00-00 ----------------------------- The smb.conf file is pretty standard, unless I've missed something obvious: ---------- smb.conf --------------- # # Samba for Linux # [global] workgroup = SNS netbios name = SNSIX server string = %h wins support = yes name resolve order = wins lmhosts hosts bcast domain master = yes local master = yes preferred master = yes os level = 35 dns proxy = no security = user encrypt passwords = true hosts allow = 10.1.1.0/255.255.255.0 127.0.0.1 EXCEPT 10.1.1.1 hosts deny = ALL socket options = TCP_NODELAY IPTOS_LOWDELAY # Logs log file = /var/log/samba/log.%m max log size = 1000 syslog = 0 panic action = /usr/share/samba/panic-action %d # shares [data] path = /mnt/data writable = yes user = sns -------------------------------------- Thanks in advance for any suggestions on how to resolve this problem. I want to move our servers over to Samba/Linux, but can't until this problem is resolved.
