Hey guys.
I just installed freenas on my readys ultra pro 6. Copiing the data back on it i realized a drop from about 103MB/s write to nas which i had before on a raid with 1 redundant disk to like 13MB/s using a gbit lan. I would need some advice on which hardware components to add/replace here. And which things i might have to configure to reduce some bottlenecks. maybe anything pops to your eye.
specs:
RAM: 1GB
CPU: Pentium(R) Dual-Core CPU E5300 @ 2.60GHz
HHDs: 4*2TB
I did set it up as RaidZ1 with the wizzard so far. its l4z compressed (is that a large performance hit?)
I was thinking about getting 8GB RAM for it as the installation already said 4GB would be recommended size.
Next i was thinking about adding SSDs for ZIL and L2ARC. Im not sure if i need two of them and i dont know which ones to get (model?). I was thinking about getting 2 and creating 2 mirrored partitions which each reside on 50% of the space of each SSD. One for write and one for read cache. Is mirrored a requirement here for some security reason? Else i would only get one. I didnt want to spend enourmous ammounts of cash here. Its for a home enviroment with about 30 network attached devices where i want to do up to like 2 to 4 HD streams in parallel. I usualy work with some GB worth of data which i analyse and crunch on for work which are stored on the nas as well. Apart from that i have main/home partitions for 6 people on the box for everyday normal data.
Would two of the Intel320 SSDs

cut it for me?
I think i would need/aim for read or write performance of normal files on the nas of ~50MB/s. anything between 50 to 100 MB/s would be better ofc.
Just checked workload of the CPU beeing 15-25% for the smbd process so that seems to be fine. RAM on the other hand seems to be a problem.
Mem: 152M Active, 67M Inact, 657M Wired, 8K Cache, 528K Buf, 90M Free
ARC: 341M Total, 1391K MFU, 272M MRU, 6125K Anon, 2618K Header, 59M Other
Swap: 8192M Total, 209M Used, 7983M Free, 2% Inuse
PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND
8561 root 1 52 0 335M 18432K piperd 0 28:48 12.50% smbd
Thanks for any advice!
