Slow SMB Read/Write Speeds

[jajross]

I am very new to TrueNAS and have set up a server to host two SMB Shares - I have set this up but only get ~60MB/s read/write on each share.

Show : Server Specs

CPU: Intel i3-13100
RAM: 1x16GB DDR4
MB: MSI H610M-B with Intel I219-V NIC
PCIe NIC: Intel I210 1Gb
Boot Drive: 240GB SATA SSD
NVMe Drive: 4TB PCIe Gen4
HDD: 2x2TB 3.5" 7500RPM

Pool 1: 4TB NVMe (single drive)
Pool 2: 2x2TB HDD (striped)*

*Currently testing the system before deployment - this will contain multiple larger drives in RAIDz

I am confused why my SMB Shares for each pool have the same read/write speed as the HDD should reach read speed between 80-120MB/s and the NVMe should read around 3500MB/s (due to motherboard M.2 Gen3). I know my NICs are going to bottleneck down to 1Gbps = 128MB/s but I am currently getting half of that!

In my tests, I have used a MacBook Pro and used Blackmagic Disk Speed Test and this has been the only client connected to the NAS.

Any help or advice would be greatly appreciated!

Morning @jajross - welcome!

What version of macOS is the MBP running? We've seen some slower-than-expected results from newer builds especially, due to them using particular settings for SMB and especially extra pieces of metadata that get written alongside - I'm not a Mac user myself, so I can only relay what I've heard from others.

Are you able to test through a different source machine (eg: Windows, Linux) just by copying files on and off, or is the intended use case of the system going to be exclusively macOS?

Hi @HoneyBadger!

Thanks for your quick response.

MBP is up to date with Mac OS Ventura 13.3.1. (M2 Max, 64GB)

I will run a test through Windows now, but the use case of the NAS is exclusively for Mac as the NAS is for Final Cut Pro storage - I am hoping that I will be able to edit directly from the NAS once I get a 10Gbit NIC but not wanting to do that upgrade if there is something else causing the 60MB/s bottleneck.

Did you get to the bottom of this?

I am experiencing similar issue.
