Hi Everyone,
I've been experimenting with my home TrueNAS rig for the past several weeks, mostly out of curiosity as I begin planning deployments for business use cases in my professional life.
The TLDR, Am I doing something wrong? I am seeing little difference in performance between the old Supermicro server and my new Dell server. I am seeing little difference in performance between my two pools.
I know I'm not using mirrors, and this is not a performance-oriented build, it is a storage-focused one. However, I am not seeing any benefit from all of the additional RAM, L2ARC and SPECIAL devices??
I have a Dell R720 running TrueNAS. It has:
Anyway, I've built this system to replace a Supermicro server with a Supermicro X10SLL-F, E3-1265L v3 and 32GB of ram. Prior to the upgrade, there was no flash in the system and it had significantly less memory. SMB shares appear to be no more, or less, performant than before. ISCSI performance is marginally faster (sync=off)
Additionally, the SMB shares on the "prod" pool (top) are no faster than the "backup" pool (bottom). This is coming from my 10-gigabit (Intel X540-T1) NIC:
Atto performance is similar. The really is no discernable difference in performance between the two pools. I get that this is not apples to apples, but really, I was expecting more from the "prod" pool. In some cases it's slower than the "backup" pool, and faster in others.
Additionally, L2ARC hit rate is abysmal. I cannot explain the gap at noon.
