Sorry for may bad English!
I'm new to forum but old freenas user.
I have a supermicro atom board X7SPA-HF with D525 processor with 2 embedded Intel nic 82574L. My problem is that i can't get more than 500-600 MBit/sec with iperf test on gigabit connection.
I tried many things read on internet; disable autoselect and forcing to 1000 mbp/s full duplex, disable advanced power management on bios board, direct cable connection to bypass switch and modify following parameters:
net.inet.tcp.recvbuf_max=16777216
net.inet.tcp.sendbuf_max=16777216
hw.em.rxd=4096
hw.em.txd=4096
I think it's software or driver issue because i tried to install ubuntu 12.04 on usb disk and, with iperf test, i can get around 900 MBit/sec without any changes.
I'm using FREENAS 9.2 x64 but i tried 9.1.1 release and NAS4FREE 9.1 with same dropped bandwidth.
ifconfig on related nic
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=4219b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,WOL_MAGIC,VLAN_HWTSO>
ether 00:25:90:38:2e:6c
inet 192.168.1.11 netmask 0xffffff00 broadcast 192.168.1.255
inet6 fe80::225:90ff:fe38:2e6c%em0 prefixlen 64 scopeid 0x5
nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
media: Ethernet autoselect (1000baseT <full-duplex>)
status: active
Anyone of you has the same nic controller?
If so, how can i get more throughput?
Thanks
