Slow network troughput freenas box ?

[850cc]

I have a DELL T300 with Xeon X3323, 20GB RAM, 4 x SATA WD 3TB in raidZ1

Write speed via terminal and "dd if=/dev/zero of=testfile bs=1048576" give me 166MB/s
Read speed via terminal and "dd if=testfile of=/dev/zero bs=1048576" give me 200MB/s

However via network 1Gb cable to my mac and nfs i get with a big ISO file of 20GB : 35MB/s write speed and 90MB/s read.

I know that a 1GB network can only give 90-100MB/s but i find the write speed slow.

Any advice ?

Episode 2 : I disabled the on onboard NIC and added a pci-express intel network card.
The performance was even a bit lower than the onboard nics.
Please help, this can be better ?

Did you figure this one out? If not, post the output of ifconfig using Insert -> Code.

with AFP i get 80MB/s write/read which is good for me
