Hi!
I had a system with this specs:
Truenas Core 13.0-U2
CPU: i7 920
RAM: 24GB drr3 1066mhz
NIC: Asus 10Gbit
with raidz2 4x14TB Exos and 250GB SSD L2ARC cache.
It topped out at around 3Gbit/s both reads and writes with the CPU at 100% all cores, which I expected as it was really old hardware.
I upgraded to:
CPU: i7 6700k
RAM: 16GB ddr4 2133mhz
Same NIC
Same storage.
Now for reads I get 6Gbit/s with 1 core at 100% and the rest idle, around 14% total usage.
And for writes I get the full 9+ Gbit/s with 1 core at 100% but more usage from the rest of the cores, at around 30% total usage.
I did this tests with OpenSpeed test running in a Jail.
Iperf3 has similar results.
Mac Studio with 10Gbit NIC as server and Truenas as client: 7Gbit/s
Truenas as server and Mac as client: 9.5Gbit/s
with similar CPU usage a s with Openspeedtests.
Would I just need a more powerful, specially in single core, to avoid this bottleneck?
I delidded the CPU and used liquid metal, so temps are great, 27ºC idle, 35ºC in use. So maybe overclocking might fix this?
