Bandwidth performance.

[shadex]

Hola! This is my first time posting here.

So far, so good with my setup. Should I add NVMe as a cache drive to enhanced my bandwidth? I have 1 Gbps router and seeing 50 MBP/s instead of 113-125 MBPs as advertised, it's not that I am complaining or anything; HDD is known to go around 70-133 MBPs.

Thanks.

Please, as per the forum rules, describe your hardware and pool setup.

I AM TRULY SORRY! .

i3-2120 (yes, very old, but works flawlessly).
8 GB DDR3.
1 TB WD.
110 GB SSD.

Planning to use B350 motherboard later on with 2200G. WOOTAGE!

HDD can give the 133 MB/s only on perfectly sequential read. 50MB/s is a decent number in that situation. To get more you'd need some faster storage, either mode HDDs or some SSD. It makes no sense to add one NVMe as cache to one HDD.

What make and model of motherboard are you currently using? Many boards use a Realtek chipset which is known to provide lower performance than Intel or Broadcom alternatives.

Thanks for the additional information. What we still need is how you connect things (a router and a switch are totally different things) and what testing you did to get the results mentioned in the original post. Also, the following things are still missing:

• Current motherboard
• Switch/router model
• HDD model
• SSD model
• TrueNAS version
• Client machine
• Software used for testing
• File number and size
• Number of iterations the test was run (cache implications etc.)

What helps with such descriptions, is to put yourself into the shoes of the readers. Can the reader fully(!) understand the setup and scenario with only the information provided?
