Who achieved speed of record on samba more than 80 megabytes per second?

Question

linux

The second day I'm already wiser, I use zero soft raids for tests, from 4 and 8 disks, up to 300 megabytes per second pour from raid to raid.
centos 5.5 system
Tried samba 3.0 and 3.5 same results. I watched various optimizations, as
samba is not particularly optimized, not a single setting affected the upload speed. the overall speed is the same and is divided into two fills. Thinking about jumboframes, but this is not appropriate everywhere. Hardware server mother from supermicro processor i7 RAM 12 GB Network on a gigabit long switch

Answer 1

well, 1 Gbit max 100 MB per second + costs, 300 meters per second on such equipment will not be.

Answer 2

when aggregating two ports, you can achieve speeds in the region of 120mb / s (from memory)
when using iscsi, it achieved around 250mb / s.
used freebsd.

Answer 3

You should test, say, FTP, or even run some kind of network benchmark - if the speed remains the same, you will need to look for a network problem.
If the speed increases more or less significantly, the problem may lie in the Windows machine. Then you have to look for answers to the questions:
* Does it support SMB 2.0?
* If not, is SMB over TCP used directly, or is there an archaic "SMB over NetBIOS over TCP/IP" pattern?

Answer 4

Achieved a speed of 105 MB / s for reading from a software RAID0 on 2x HDD and 80 MB for writing.
I can say that I rummaged through a bunch of material, and tried to play with buffers. This speed was achieved under FreeBSD, samba 3.0 from ports, with the Async write option (or something like that). In Linux, samba was limited to 60MB / s, while FTP did 110+ here and there.

Answer 5

The problem is most likely in your network hardware. or setevukha, or a switch do not issue an honest gigabit. I have a cheap Noname switch at home - I couldn’t squeeze more than 50 MB / sec from it.
