CPU performance is very important in 10GbE enviroment

Hi guys,

I originally thought CPU performance should not be a big concern of building a NAS. It is true if you only use it over 1GbE network. Even a low power atom/arm board would serve good.
However, in 10GbE environment, you have to use a good CPU to take out the best performance of your build. I am still very surprised by the result from my recent test: about 200mb/s AFP write speed drop from switching i3-4130 to G1820.
but not so much influence on read speed.

these were achieved through AFP.
i3: write~900mb/s read~1070mb/s stress usage~60%
G:write ~700mb/s read~1070mb/s stress usage~100%

NAS build:
i3-4130 vs G1820
asrock h97m-itx
16gb ram
4*5TB Hitachi RAID 5
Mellanox connect -x2 dual port 10GbE (cheap stuff from eBay)
omv 2.15

Hackintosh:
xeon 1231v3
32GB RAM
Solarflare 5126f dual port 10GbE (got a good deal on eBay as well)
3*Samsung 850 evo 250GB RAID 0(OS X raid0)

forgot to mention this was done with Blackmagic Disk Speed Test

ah. I just try to share a thought on the CPU performance. don't really want to test it all out
