    Slow transfer from NAS to ESXI local datastore

    phuz Novice

      I currently have my VMs on a NAS, but will be migrating them to local drives on the ESXI server itself.  I am trying to copy one of them over, through command line (cp /vmfs/volumes/NAS/(file) /vmfs/volumes/datastore1) and it's transferring at about 17-22mbps.  It's a non-crowded 1gbit network, so why is my transfer so slow?  If it was just this one single VM, I would write it off, but I have 20 more VMs to migrate and would like to avoid these delays.

          If I run an internet speed test from within a VM on that host, I get speeds of ~200mbps, so the NIC is not the issue. 

          I tried using WinSCP to copy a large file from my laptop to the ESXi host and I got the same slow results (~16mbps). 

          I'm baffled.

            In case anyone else runs into this on ESXi 6.5, it has to do with a bad version of the AHCI driver.

             

            See here for fix as it worked for me.  I'm not transferring to local datastore at ~500mbps.

              Thank you very much. I confirm that this issue was bad AHCI driver and your link provided the correct fix (upgrade to update 01-build 5969303).

              In case anybody would like the esxcli upgrade command using the vib (update-from-esxi6.5-6.5_update01.zip) along with results here you go:
