I've just started using Unraid and want to use it to download stuff and followed the Trash guides. I'm totally new to this all, but I think I'm running into limiting factors here when it comes to my CPU or maybe I'm missing a setting in Unraid.

I've noticed when downloading for example when using qbittorrent, speeds max out at about 80MiB/s but also drop quite badly, even worse when multiple downloads are active. So then the average comes down to about 50MiB/s even though I have a gigabit connection, which I can easily fill up usually within windows, or when writing straight to /mnt/cache/data for example.

I'm using an AMD 2400g, my cache disk is a 8tb SSD. And have an array of various HDD's and a 16tb parity disk. Can my CPU be a limiting factor?

I ran a quick write test to support this theory:

root@NAS:~# dd if=/dev/zero of=/mnt/user/data/testfile bs=1M count=1024 oflag=direct 1024+0 records in 1024+0 records out 1073741824 bytes (1.1 GB, 1.0 GiB) copied, 1.71472 s, 626 MB/s root@NAS:~# dd if=/dev/zero of=/mnt/cache/data/testfile bs=1M count=1024 oflag=direct 1024+0 records in 1024+0 records out 1073741824 bytes (1.1 GB, 1.0 GiB) copied, 0.893554 s, 1.2 GB/s

I really want to at least get to about 100MiB/s

Do you guys have any tips, or are there any tests I can run to show what the bottleneck is in this case?

If this is writing to the pool, could be a slow device, start by posting the diagnostics to look at the hardware.
