Re: [Samba] Performance issues
I have seen performance issues where a Windows client (Explorer) takes a while to display a file listing on a remote computer, but then it accesses it just fine. Generally speaking, this is the opposite of what you describe, but it could be related. In investigating this, the problem (not the symptom, the actual problem) turned out to be invalid shortcuts to network shares. These invalid shortcuts are left behind from when a server or share once existed on the network but has since been removed. When initially browsing the network, Windows attempts to access all the remote shares it knows about BEFORE displaying any listings, rather than accessing the remote share only if the user requests it. This seems to be especially problematic with Microsoft Word and Excel when opening documents. There are several places to look for these stale or invalid shares: 1. "My Network Places" -- Open this up, and delete any shortcuts that point to remote servers or shares that no longer exist. It's actually safe to delete ALL of the network shortcuts (named like "Someshare on someserver (servername)"). Usually these are created automatically. 2. "My Computer" -- Disconnect (remove) any network drive mappings that point to nonexistent shares or servers. 3. "Desktop" -- same thing as My Network Places; remove any invalid shortcuts to network shares. I don't think that these cause a problem as described above, but it can't hurt to remove them. 4. Registry -- HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\MountPoints (MountPoints2 in XP or later) -- there may be subkeys in the form of ##server#share. Delete any keys that point to nonexistent servers or shares. Lastly, if you are using Windows XP or later, disable "Automatically search for network folders and printers." To do so, open My Computer, click Tools - Folder Options, View tab, and it's in there. When enabled, Windows will fill up your "My Network Places" with shortcuts to any network shares it finds, and will fill up your Printers folder with "Auto" printers. Note that each of these things are on a PER PROFILE basis. You will need to check each Windows user login for these issues. I can't guarantee that this will solve your problem, but since you mention that you've replaced a server, there's a good chance that there are some stale & invalid shortcuts lying around. It could be that Windows periodically is going out there looking for these nonexistent shares, and in the process interrupts your connection. Hey, it's worth a shot. --Jonathan Johnson Ryan Wright wrote: List, I apologize for the "newbie" nature of this post; I am sure there is an easy answer somewhere, but I've tried all the search terms I can think up and can't find it.

You need to keep very accurate statistics on what is going on on the server over the copying period to be able to debug this. I'd try running vmstat 1 (every second) and capturing the output over the copying period to try and catch this.

It also seems as if the process only ends when the client machine is rebooted. When I use the server in security = user mode, every time a new connection is made from a different client a new process is started. It also only seems to kill the process when the client is rebooted. I end up with a lot of processes running on the fileserver and sometimes the machine locks up and complains about the max file limit being reached. I have found a workaround by increasing the file-max value in /proc/sys/fs. I was just wondering if there is a way to get the processes to die as soon as the client disconnects from the server - maybe I have omitted something when running the configure command?? I was also wondering if it is the default behaviour of samba to spawn new processes every time a connection is made? Is it possible to change this behaviour? thanks in advance, Mark Le Noury -- To unsubscribe from this list go to the following URL and read the instructions: http://lists.samba.org/mailman/listinfo/samba -- To unsubscribe from this list go to the following URL and read the instructions: http://lists.samba.org/mailman/listinfo/samba
