What are the speeds that you guys are getting using samba. Over 1 gb network I only get 12 mbs. Can somone post copy of smb.conf?

I was getting about the same from Windows, but from Mac OS 10.6.8 it's somewhere between 25-30 MB/s

I just copied a 3 gig file from my unraid.. it was averaging aroudn 92 megabytes a second...

But lots of factors here, how fast is the drive you are copying from?

How fast is the drive you are copying to? is it ata/sata etc etc?

How good are your network cards?

etc etc

 

 

From Windows I had a HP 6730b notebook, so some lousy 5400 2.5" disk probably, I don't even care. Still 10-12 MB/s is slower than USB2, so that's clearly an issue. My Mac has a WD15FALS disk, 7200 with decent cache. To a Windows server my copy was about the double. The network is Gigabit, cables are Cat6. NIC speed is auto, auto-negotiated to 1000/full. No cache drive in the unRAID server obviously.

Install RAM disk and try copying NAS -> RAMdisk to eliminate influence of HDD. You'll see if your slow HDD is a bottleneck.

For my case I'm 100% sure it's not the disks since when I was experimenting with Windows Server 2008 R2 the speeds were much faster.

Well hdparm -tT shows 126 to 140 for drives. I was messing with smb.conf

So maybe now not only socket options = TCP_NODELAY IPTOS_LOWDELAY SO_KEEPALIVE SO_RCVBUF=1048576

not optimal. I remember getting 60 mb/s in past.

12MBps is maximum for a 100Mbps links. What does "ethtool eth0" show? Are you sure the client is connecting at 1Gbps?

For me it was one of the first things to check. It's 1000/full. Now I'm getting speeds from 25-30 MB/s which is acceptable but I've read other topics saying about 40-50. I just want to know where the bottleneck is or what to check.

40-50 is slow. 

As I said I am getting around 90 megabytes a second. nothing special, these are green drives that spin at like 5900 rpm.

I have intel nics though and a very good switch.

 

with unraid, when it comes to reading from a disk, it should be as fast as the disk can be read, as no parity is done then.

 

 

My config is a HP Proliant Microserver, I can think of the driver for the NIC, it's a Broadcom BCM5723 (HP NC107i). As I said I had no issues when this box was running Windows.

 

It's the write speed I was talking about, the read is not that important to me it's just for storing media, and backups. It can stream 1080p with Twonky without any issues.

Ahh well perhaps you should have mentioned that , huge difference between write and read.

I get about 25-30 for write speed

Thanks for the feedback

We should post some ideas to optimize samba. My hdparm -tT shows 300
