Hi Guys
I've done some tweaking with performance when i was running 4 disks in raid 1+0 under freenas and passing through using NFS to my esxi lab. I added an ssd running zil/l2arc and all was well.
Finally decided to upgrade the storage, so i got a 750GB samsung 840 EVO and added to my freenas box.
however when I map over NFS i get really poor performance.
i've tried with sync enabled/disabled
locally on the freenas box i'm getting 300Mbps+ but from ESXi i get nothing like this.
running low end vm's i'm getting write and read latencies over 1000ms, can't make sense of it since the source drive is an SSD it should be lightning fast, any ideas?
