Great a reply!!! I thought everyone had given up on me! OK for the specifications, it's a Compaq ProLiant 2500 server with: - Dual Pentium Pro (200MHz) - 256 MB EDO RAM - 36GB RAID(0) Compaq Raid Array (two 18GB SCSI disks) hdparm -tT gives: /dev/ida/c0d0p4: Timing cached reads: 192 MB in 2.02 seconds = 95.11 MB/sec Timing buffered disk reads: 46 MB in 3.03 seconds = 15.18 MB/sec - Compaq Netelligent Integrated 10/100 TX NIC
I can do FTP at 9 MB/s but the absolute max I can get samba up to is about 4 MB/s. I've tried installing version 3.0.14a, I'm compiling the old version 2.2.12 as I write this... I managed to get quite a performance boost when I compiled the latest version for the i686 architecture (100% performance increase using smbclient from another machine). What is annoying is that and NFS client in windows doesn't perform better than the samba client (using a Linux client NFS is slightly faster than FTP). I'm going to try compiling samba 3 without ACL support, then I'm going to try to install samba 2.2.12 if that doesn't solve it then I'll settle for a hardware issue and try to get hold of a 3C905 (3com NIC), after that I'll be out of ideas...

Hello, I've seen several people post similar issues as yours. Perhaps it is hardware related? Can you post your hardware specifications? I've done some benchmarking over the past few days and I'll show you what I have: Samba Server AMD Duron 1.3ghz Abit (?) k7a or something like that motherboard (KT133 chipset) 512mb PC133 SDRAM Intel gigabit NIC WD 120gb hard drives Netgear gigabit switch (no jumbo frames) Fedora Core 3 Kernel 2.6.10-1.766_FC# Samba 3.0.10-1.fc3 Now I can FTP to and from the server getting in the 14.5 - 15 MB/sec range. When I use Samba I get from 12.6 - 14.4 MB/sec. I use a 4gb .gz file for testing. Since my server does many things, I've noticed that it can take a minute or so for the transfer rates to settle down. hdparm -tT /dev/hdc average results: Timing cached reads: 306.785 Timing buffered disk reads: 33.785 Given my hdparm results, I should be able to do better than 14MB/sec. Next I'll try copying from one drive to another and see how long that takes. If needed, I could post my smb.conf file but there really isn't anything in there. I just used the default one and added my share info. So, in short, I don't think there is a problem with Fedora Core 3. There could be some issue with your hardware or configuration. Perhaps the new version of Samba is a memory hog and requires 256mb or more to run smoothly? I guess you could take a look at top and see if you have any high states. -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/listinfo/samba -- No virus found in this incoming message.
