Performance Issues on 6.3
Hi i have a server with four disk atached, 2 raid 0 and 2 raid 1. Im getting a low performance on file trasfers over network to windows clients i get only about 30MB/s. Looking at gstat i got both disk are trasfering 15000kBps each over a gigabit connection(client and server). How can improve performance for my data server? uname -a: FreeBSD mlds.morpholab.loc 6.3-RELEASE-p1 FreeBSD 6.3-RELEASE-p1 #0: Sat Feb 23 22:12:17 UTC 2008 [EMAIL PROTECTED]:/usr/obj/usr/src/sys/MLDS amd64 mount: /dev/mirror/gm0s1a on / (ufs, local) devfs on /dev (devfs, local) /dev/mirror/gm0s1e on /tmp (ufs, local, soft-updates) /dev/mirror/gm0s1f on /usr (ufs, local, soft-updates) /dev/mirror/gm0s1d on /var (ufs, local, soft-updates) /dev/mirror/gm0s1g on /raid1 (ufs, local, soft-updates, acls) /dev/stripe/st0a on /raid0 (ufs, local, soft-updates, acls) devfs on /var/named/dev (devfs, local) dmesg: smb.conf(global only no shares) [global] workgroup = MLN server string = Data Server syslog = 0 max log size = 50 printcap name = cups os level = 100 preferred master = Yes domain master = Yes wins support = Yes #hosts allow = 172.16.1., 10.8.0. #interfaces = lo0 nfe0 re0 printing = cups cups options = "raw" print command = lpq command = %p lprm command = nt acl support = yes socket options = TCP_NODELAY debug level = 4 # security = server ifconfig: xl0: flags=8843 mtu 1500 options=9 inet # netmask 0xff00 broadcast # ether 00:04:76:31:e8:94 media: Ethernet autoselect (100baseTX ) status: active nfe0: flags=8843 mtu 1500 options=1b inet 172.16.1.1 netmask 0xff00 broadcast 172.16.1.255 ether 00:19:db:66:63:72 media: Ethernet autoselect (1000baseTX ) status: active Both RAID got low performance, where can i check to fis that problem? -- mmm, interesante. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

How did you determine that it is your RAID that is performing poorly, and not your network card or your samba or something on the other system?

When im rebuilding the RAID 1 i got about 40mb/s from each disk. I think its a network issue or samba, but i dont know where to look at. Thanks.

You can eliminate the network pretty quick, open a command window on your Windows boxes then FTP into the server (turn on FTP on the server of course) and transfer some files back and forth. Have you perhaps considered subscribing to the samba mailing list and asking them? Or looking through the samba mailing list archives?

Tahnk you How to rule out the raid: 1) create a memory disk, in your case I'd go with 256MB if you can spare the memory. 2) Put a file on it, size ~210MB (7 * 30MB/s, should give ample time to let the transferrate go up) 3) share it via samba 4) Download it through one of the clients If the transfer rate is still low, it's not the raid. Install a bandwidth monitor then (net/bmon for example) and see if the traffic is actually higher then the 30MB/s, eating the rest of your bandwidth, investigate samba issues, switches, clients (are they really configured Gbit?). If the transfer rate is much higher, you're pretty safe to assume it's a disk issue. Manpage to read: mdconfig(8) - choose swap backed btw. -- Mel Problem with today's modular software: they start with the modules and never get to the software part. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

One of my harddrives (RAID 1 ) goes offline. I made the test with only 1 disk trasfering a 1.7GB file trought FTP and samba. Samba got about 24mb/s and ftp got about 45mb/s from the single disk both. Samba takes the twice the time than ftp, it is my bottleneck anyone has any patch/suggestion to improve the samba performance on freebsd?

Wern't you claiming gigabit here? Seems if it was gigabit then 45mb/s is a problem, eh? One more test for you. Map a drive on your 'doze system Drop to command line (start->run->cmd) xcopy a sample file from c: to the mapped drive xcopy a sample file from mapped drive back to c: Time it Compare the times, what are the results? What are the results in comparison with the other tests?
