SMB3.0 Copy from FreeBSD to Windows 2012 R2
Posted on 2015-01-05
I was hoping someone could help explain this for me.
I have a Windows 2012 Server, I have setup perfmon to record the Disk Read Bytes/Sec and Disk Write Bytes/sec of a local disk. I have the lowest sample set to 1 second.
I am copying a file from the local disk to an Isilon Node (running free BSD) everything is perfect, numbers look good.
The problem is copying from Isilon to the local disk. I see values that 'hiccup'. Typically I get several hundred megabytes for a few seconds and then 0, then back high then zero again. The high numbers are always at least one in a row up to 6 (so 1 second to 6 seconds) the drop is always 1 second....
NOTE: I have verified that I am connected and transferring with SMB 3.0.
I am not seeing this with SMB 2.0 copies so I am thinking this is something to do with SMB 3.0??
