I did not set max protocol to SMB2 in smb.cnf, I don't want to force SMB2 selection if SMB3 can be used by a client. The machine is a Windows 7, so is SMB2 compliant.

Hello Jeremy, Andrew, All, I can now indeed confirm that my test scenario runs MUCH faster when executed against a Windows 10 SMB2 server than against Samba (test scenario takes ~ 18 seconds using a Windows SMB2 server as opposed to ~ 300 seconds when the server is Samba 4.6.5). But, most interestingly, the reason for these performance gains is NOT - as assumed by Jeremy - that the number of client-server request/response...

Ah, ok, "directory handle leases"... Ouch, I see... :-( In this case, I will first repeat my test scenario with a Windows SMB2 server and report back here. Based on the results of this exercise, you can then advise whether you still want to move this to smb-technical and raise this with Microsoft folks (who still might have a simple workaround "fix" to improve their SMB2 client performance with a Samba serve...

Hi Samba list! I was very excited that SMB2 is finally working with samba 3.6.0 - great job!! I just know that SMB2 has a smaller command set compared to SMB1 and this, beside many other rebuilds of the code makes it faster As I am completely new to the file transfer protocol world, I want to ask a few basic things: - is Samba backwa...

Good morning, folks. I've been driving myself to distraction trying to test out SMB2 performance under Linux. I see that the Samba on RHEL 5 is relatively old, I'm dealing with an upstream NetApp fileserver that is configured for SMB2, so I've got clients to test. The Samba on RHEL 5 is relatively old, 3.0.33, with samba3x-3.5.4 alternatively available, and cifs-utils-* av...

Greetings list, I just upgraded to samba 3.6.0 trying SMB2. Though Windows 2008 R2 can work with SMB2 shares just fine, I'm unable to access SMB2 shares with mount.cifs or smbclient, even with "-m smb2" specified -- I get this "Unrecognised protocol level smb2", whereas smbclient comes with samba-client-3.6.0-63.1.rpm. So is this...

...some new samba installations from ubuntu 12.04, centos 6.4 and debian wheezy. All running in a VM on a XenServer. The samba servers are member of a 2008R2 domain, using smb1 protocol all are running fine and we get a constant 90MB/s (big file transfer) on our 1GB network. We would like to enable smb2 protocol for performance reasons, but when we do enable SMB2 (max protocol = SMB2) file transfer speed drops to 50-60MB/s (one big file) instead of the 80-90MB/s we used to get before. We noticed when this happens the cpu is at its max instead of 60-70% when using smb1. iostat doesn't show...

I am trying to setup a SAMBA server using 3.5.0rc2 to test SMB2. Without using SMB2, my windows 7 was able to browse the public share listed on the server anonymously. However, when SMB2 is enabled, a network error message is always popped up when I try to browse the samba server from Win 7. I have looked at the trace. It seemed to me that Win 7 had troub...

Just saw that, as well. After running the commands to enable SMB2 & SMB3 and rebooting...no luck. Will keep searching for other registry settings.
