I have a problem with slow writing speed via mapped network drive (samba) on Windows Server 2012R2.
I'll describe my network and tests below:
I have two computers both running W8.1 (Desktop and Notebook) with one 1gb/s NIC,
then ESXi 6 Update 2 running two VM's (WS 2012 and debian).
Both VM's are located on SSD in the same storage, both have one Virtual NIC - VMXNET3 (same Port group (two physical 1gb/s NICs in one vSwitch)).
WS2012 is not in AD.
Folders to share:
W8.1 Desktop - "share"
WS 2012 - "sharing"
debian - "test"
I did a few test by copying a single file (~700MB), everytime with different file, so it wouldn't be somehow compromised tests:)
Here are the results, speeds of transfer were very constant:
Windows 8.1 Desktop (uploading) > WS 2012 = ~33MB/s (downloading)
Windows 8.1 notebook (uploading) > WS 2012 = ~33MB/s (downloading)
debian (uploading) > WS 2012 (downloading) = 123MB/s (I mapped folder "test" in windows and downloaded the file)
Windows 8.1 Desktop (uploading) > debian = 113MB/s (downloading)
Windows 8.1 Desktop (uploading) > Windows 8.1 notebook = 113MB/s (downloading)
Windows 8.1 notebook (uploading) > Windows 8.1 desktop = 113MB/s (downloading)
WS 2012 (uploading) > debian = 120MB/s (downloading)
WS 2012 (uploading) > Windows 8.1 Desktop = 111MB/s (downloading)
I will be glad, if anybody helps:)
I've found many similar guestions, but I did not find the solution:(
Thanks
