Samba on my File Server

crep · 05-01-2005, 11:47 AM

Hey all,

I have a SCSI array of 8 disks. This plugs into my SCSI card, and after being setup in the SCSI bios, appears to the OS as one disk. Woop-de-do.

My box is kind of lame. I figured that over the network, the file transactions couldn't be THAT hard-core, so I used one of my 266 MHz speed demons, with 192 MB RAM. (Pluss 100 meg NIC)

SO: I put SuSE on it. Runs fine, I can write to the disk and all that. I setup the samba server, that works great. So, the samaba share "stuff" goes to /share, which is where the SCSI array is mounted.

I go to my desktop and start copying over my files. Rats: I only got to about 18 MegaBITS on the network: that's about 2 MegaBYTES a second. Hm.

I get a shell on the file server while this is transfering. Turns out, the process smbd (the samba daemon) is pegging the CPU at about 60%, with the remaining 30-40% being used by the SYSTEM.

So my question is, what's up? I can't imagine that file transfer things take THAT much CPU, should it? Did I configure something wrong?

Thanks,

well samba shouldn't have a problem with that.

Did you configure something wrong? How do we know? you didn't show us your config... we're not psychic.

the most common "performance" fix is to increase packet sizes for samba. check you have the line

Code:

        socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192

in your smb.conf. this is more on the networking side though, not the cpu side...
