Re: CIFS Performance

DATACENTER_NEO · ‎2013-06-03

Hello,

i have a CIFS on netapp 2240, and this throughput is only ~40MB/s on 10Gb network, when my client is windows, and when my client is linux the throughput is ~120MB/s.

If i configure a share on windows 2012 my throughput is ~130MB/s with clienta windows and linux.

My problem is betwen client windows and netapp CIFS. I configure many options on netapp but the performance is always the same.

my options configurations is:

cifs.LMCompatibilityLevel 1

cifs.W2K_password_change off

cifs.W2K_password_change_interval 4w

cifs.W2K_password_change_within 3600h

can i do more something to emproove this (client side or server side)?

Thanks,

there are two ways. .

1. get a netapp performance engineer to review our perfstat

2. find cifs performance

a. get the cifs stat output

b. check for cifs domaininfo

c. round trip to your dc

d. roud trip to your vscan or fpolicy server

3. what is the hostname/SN number of your system. is it sending ASUP ?

Hi,

The CIFS/SMB protocoll is not very performant. If you have newer clients than win2k3 and XP, SMB2 will give you much better performance. I see, however, that you aren't using it. Enable it on the filer CLI with 'options cifs.smb2.enable on' . Do take some time to read the documentation as well. Many of your questions will be answered there with much better authority than you will get on Communities.

You might also want to try updating to a much newer 7.3.x release to take advantage of some performance enhancements in ONTap.

Ok,

but on other netapp i have the same problem, on ontap is 8.x, interface is 10Gb (FAS2240) and smb 2 enable.

can i sent the same informations for your analysis ?

Thanks

on my tests i have this values:

Windows 2012 -> NetApp = ~35MB/s

Windows 2008 -> Windows 2012 = ~100MB/s

Windows 2012 -> Windows 2008 = ~90MB/s

Windows 2008 and 2012 are in within a LUN on NetApp.

shaunjurr · ‎2013-06-05

Hi,

It's still all a bit confusing because you are not specific enough about which Netapp you have sent results for. The first results here show that you aren't using smb2. The new cifs stat output looks more like you are using smb2.

Try to limit your posts to a minimum of relevant information and keep the tested combinations well labeled. Also, watch the output of 'sysstat -x 1' while you are doing your tests. Use a new empty volume without any dedupe/compression. Try using a single identical file for all tests or a single config in a program like "iometer".

The 35MB/s you post is pretty typical "smb1" speed.

S.

DATACENTER_NEO · ‎2013-06-07

Ok,

On first situation (CIFS on FAS2020) i enabled the SMB2 and my throughput is 30MB/s yet.

i need change more some cifs options?

DATACENTER_NEO · ‎2013-06-07

Result of command "sysstat -x 1" while test file tranfer.

Did you ever get this sorted out?

I have the same setting and the same slow results

CIFS signing causes a huge performance issue for us. I see cifs.signing off but it is on for SMB2 in your post. When signing is on in our environment we get 70-80MBs over 10GBe. Turn it off and we get 500-900MBs depending on the client capability.

I see Max pBlk Exhaust = 62874 in your output...

You appear to be suffering from same "pBlk Exhaust" issue we are having on our 6290. pBlk Exhaust had taken down our 8.1.3P1 6190 Windows Home Directory down once, and our 3160 3 times now over 2 years.

Causes include vcan and slow AD, however after 4 P1 cases, we have yet to find the root cause.

We continue to suspect an AD communication issue, since we do not have vcan setup. However no direct proof that anything is wrong with the AD servers.
