Re: trouble shooting samba performance
worms wrote: Hello, Can anyone point me to a guide on trouble shooting samba performance or a quick list of common issues I can check for. I've been googling but haven't found much that referenced a recent version of FreeBSD and Samba. I am running FreeBSD 7.0 on VmWare Server 2.0 hosted on a CentOS Linux box. I've used nttcp and iozone to verify that the performance of the FreeBSD 7.0 VM is good and am able to copy 6.5GB on disk from one location to another in about 2.5 minutes. Copying to a Windows 2003 server yields a 45 minute transfer time. Copying to a Windows XP workstation yields a 4 minute transfer time Summary: FreeBSD 7.0 -- FreeBSD 7.0 -- 2.5 minutes ( copying on disk ) FreeBSD 7.0 -- WinXP -- 4 minutes ( samba ) FreeBSD 7.0 - Windows 2003 -- 45 minutes ( samba ) WinXP -- Windows 2003 -- 5 minutes Both windows machines are on the same domain. I've used samba for a number of years and this is the first time I've ran into a problem such as this. So if someone could give me a good starting point on how to troubleshoot this I'd appreciate it. Thanks --Lance The numbers indicate something i've seen several times but there has been different answers to it. Sometimes it was the indication that the RAID on the Windows2003 server was misconfigured or running in DEGRADED mode. However i've also seen issues regarding TCP/IP settings. Often it can be a good exercise to try to toggle this sysctl before transfer (net.inet.tcp.delayed_ack).

Is TMPFS available on FreeBSD 6 or 7? Or do i have to settle for mfs? [venting frustration] The reason i ask is i need something very flexible when it comes to memory usage as a poor-mans shared-memory feature for a closed source data conversion app, used only occasionally but with *alot* of data passing through. By alot i mean it took our quad core xeon 3 ghz with 4 gbyte memory and 4 SAS drives in 1+0 RAID, about a day and a half to process (on disk). Simple tests (by others) using netbsd on a single cpu 3 ghz and tmpfs, it took roughly 70 minutes. Most of which was spent loading and unloading the data over the network. I'd really like that memory back after use for other things as this server is also serving databases with files etc. (PS.

If you see slower response then perhaps something is wrong. Perhaps you should call their support and verify that you do not have a mismatched duplex setting? Mismatched duplex can come from misbehaving autonegotiation or that one end is set to full-duplex while the other end is set to half-duplex, or, one end is set to full-duplex and the other end is set to auto-negotiate (which results in falling back to half-duplex). -- Sten Daniel Soersdal ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

My guess is, your path-mtu is lower at some point between you and

I've found that if I use the default sizes that are chosen by the installer using the auto option, the /usr partition fills up before everything is installed and the installation fails. If I remember correctly, the auto feature sets the sizes around the following sizes for my HDD: / ~500MB swap ~600MB /var ~1300MB /tmp ~ 500MB /usr ~3GB Perhaps it is possible to reduce / to ~128 mb? boot up and see estimate that you need several mb free and estimate double of /boot/kernel directory (if you install new kernel you get to keep the old one, therefore estimate double that directory size). Swap ... well for a successful crash dump you need as much as swap as you have memory. /var can be further reduced to perhaps 512mb or perhaps even less? if you do buildworld then /var/tmp/ might be used more. Perhaps you could merge / and /var and symlink /var/tmp with say /usr/tmp ? /tmp can be reduced, you can even remove it completely and use tmpfs for that partition. /usr needs the rest Just a (cluttered) suggestion.
