Hello everyone!
I'm new to the world of TrueNAS, made it just to store my home files in just one place!
My NAS specs:
AMD Ryzen 3200G
16Gb RAM
4x 3TB Seagate Ironwolf NAS ST3000VN007
1 pool in RaidZ1
1x Nvme 128Gb for TrueNAS OS (I thought I could use a partition of it as SLOG/ZIL, but I discovered too late that I can't)
Intel NIC Expi9400ptblk (the mb realtek one didn't do the job)
My PC specs
Core i7 8700k
32Gb RAM
NVMe storage
Intel NIC
etc
So, as you can see, it's a humble NAS rig, I don't need a lot.
My doubt is that, I was transferring all my stuff to it, and the transfer speeds would start at 140-180MB/s, and that's fine by me, but then, after 5-10 seconds, it would slow downs to a constant 50-65MB/s. If I paused the transfer for 5-10 seconds, and then unpaused it, again it would peak ate 140-180MB/s for some seconds and slow down again.
I have a modem that have a CAT6 cable connected directly into the NAS, and another CAT6 cable connected directly to my PC.
Iperf tests:
NAS->PC: 300-360MB/s, very stable speeds (seems ok, 3 times the read speed of a single drive as RaidZ1 predicted)
PC->NAS: 120-350MB/s, would change abruptly from 300MB/s to 120MB/s and up to 230MB/s again, over and over, but it averaged 220MB/s in a 2 minute test
Anyway, faster than what I'm having when transferring files from my PC to my NAS (NVMe storage over CAT6 cable to modem and them to NAS [4x 3Tb RaidZ1]) - 60MB/s
Is it something wrong? Maybe I need to add cache storage for it to run smoother??
Maybe I could run the OS from a USB stick and use my NVMe 128Gb as cache?
Thank you very much!
Have a nice day!
