Yes, I am. In my experience it doesn’t help much if most of your use is remote. Although that might change with 10gbit like you’re using. (I’m on 3x1Gbit over LACP) However, stuff that runs locally on the NAS sees a significant boost. I’m also running some games from an iSCSI LUN on the NAS, it helps a bit there as well, but I recently added a local SSD cache to my game system to cache that so the cache on the NAS became kind of redundant there. This makes my game disk as large as I want but with anything I used recently at local NVMe SSD speeds.
I also skip continuous reads/writes as the array is fast enough to deal with those. So the SSD cache is only used for small reads and writes. For storj that helps with all the smaller db operations. I think it helps my node “win the race” more often. But with every storj optimization my advantage drops as other nodes catch up.
