Hi experts,
Hope someone can help. I have been searching for weeks.
I have been using FreeNAS for many years as an SMB server. Mostly to take advantage RAIDZ2 and snapshots.
Recently, I took the plunge to add another Z2 pool with 6x2TB SSD drives and upgraded my network to support 10GB.
Through Windows 10 SMB share, I get sustained transfers of approximately 500MBps copying to and from nas to an nvme drive on the windows machine.
HOWEVER, I can sustain around 1,000MBps with FTP.
How do I go about figuring out why my SMB is slower than FTP transfers?
Since FTP transfers are able to saturate my network, does that eliminate drive and network speeds? Is this a CPU single core problem?
iPerf from windows client (single stream) only gets about 500MBps while multiple streams gets 1,000MBps
Where do I go from here on my journey to saturate my 10gbe line while doing large file transfers with Windows SMB?
Many many thanks in advance
