Re: [Samba] Performance issues
Thank you both for your replies. 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. I'll give it a try. That makes sense and won't take much time to test.

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.

I'm guessing that the machine is based on an LX or BX chipset with PC66 or PC100 ram. I looked it up and it's an ASUS P2B-LS Motherboard with the 440BX Chipset. You have 66mhz bandwidth to play with in the PCI bus. You also have 66mhz FSB thanks to the PII 300 CPU. All the benchmarking you have done (both Iperf and hdparm) both test the two subsystems individually, not together. My initial guess is that your PCI bus and/or CPU cannot drive this system at its full potential. Look at the load average on the server during transfer. The average loads are 0.23, 0.22, 0.12 I don't know what it means exactly, but i get them out of top during transfer Secondly you are running Redhat 9 with a Realtek 8169. There were a number of issues with the stock Redhat 9 kernel versus a Realtek 8169, see here http://www.linuxquestions.org/questions/showthread.php?s=threadid=14975 1highlight=8169. In fact these users are reporting only 8-10mb throughput which is exactly what you are describing. I have tested the machine with Suse 8.2 before, but there's the same problem. Maybe because the Kernel version is almost the same? (2.4.20) My advice to you is to roll a custom kernel for your system I have once compiled a new kernel on another machine, but i'm not familiar with it. Please tell me the commands i have to run for this. (optimized for Pentium 2, raid and network drivers built into kernel instead of modules). At the Moment they're both modules [r8169.o (version 2.2 from realtek site) and the raidcontroller (which is an ITE 8212)] Then perform a proper hard disk benchmark using Bonnie++ so you know what the disks are truly capable of (hdparm -t doesn't cut it in this respect).

I am having some performance issues with it and was wondering if I was doing something wrong. I have noticed that if I use samba in security = server mode, every time a new connection is made to the server from the same client a new smbd process is started. 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
