Hi Im hoping someone can help me with slow write speed issues. Ive read a lot but not sure what is relevant.
Dell T620 - ESXI 6.7
HBA Passthrough to TrueNas VM with 4 vCPU and 32GB ram
8 WD RED 3TB
VMXNET3 single NIC
ESXI is installed on a SD, and the datastore is a separate set of RAID SSD's
When I run a speed test using iperf between truenas (Server side) and a windows VM (client side) i get the following, not great but useable speeds
When running the same from either another ubuntu VM, or my desktop windows PC its a much different output
I have also tested a file transfer by both FTP and SMB from windows machine and get similar speeds (Large files 4gb+)
Currently Vswitch has 1 uplink, through a PCIE 4 port ethernet card (INTEL) and only the truenas and windows VM's are on this switch
The vswitch is configured for Jumbo frames with an MTU of 9000, connected to a meraki switch with MTU (Standard) 9578 (MS220-8P) I am unable to find an MTU configuration for my MX firewall, and have noticed that when I traceroute from my main PC to TrueNAS, one of the hops is the MX, even though both server and PC are connected to the same switch, so Im thinking it could possibly be a routing issue.
For added clarity, shares are setup as both SMB and NFS (need to be accessed by both win and linux)
Anyone any pointers? Apologies if i have missed out any required info, I have tried to be as complete as possible.
