Truenas 13.0 Core - SMB limited to ±113MiBs GB network

[puppabriggy]

New to Truenas. I'm runing 13.0 core on a i3 (specs in my signature). Although I'm connected to a gigabit network my smb traffic is limited to ±113Mbs. I've run a few tests based on other threads. this is below. This seems to be limited to my SMB service. Out of paranoia I switched out my switch but that wasn't the problem. Any point in the right direction will be greatly appreciated.

I've made the following modificatios to the SMB service settings based on forum searching.

server multi channel support = yes
interfaces = "192.168.1.12;capability=RSS,speed=1000000000"

Using the OpenSpeedTest plugin my upload and download speeds are ±987Mbps

using dd to test the pool shows the follwing if I'm reading this right I'm showing at least 3.8GBs.

root@truenas[~]# dd if=/dev/zero of=/mnt/NAS_pool_1/backup/dd_test_report2022092
5.dat bs=1024k count=20000
20000+0 records in
20000+0 records out
20971520000 bytes transferred in 5.430061 secs (3862114947 bytes/sec)

Any point in the right direction will be greatly appreciated.

Welcome to the forums. Differentiating between Bytes and bits will take you in the right direction.

You have a Gigabit network - nominal 1000Mbits/sec. Your 113 MBytes/sec = 113*8 = 904 Mbits/sec.

oohh the shame, remembering my dad explaining this very concept. Well one problem solved, thank you .
