not reaching gigabit transfer speeds

[xyz2610]

Hi everyone,

I encountered the following problem with my FreeNAS setup:
The transfer speed between my PC and my server is only about 15 MB/s. The server is running an Intel Gigabit NIC and it is connected to my router via a Cat 5e Ethernet cable. The router itself is then connected via a Gigabit Powerline Adaptor (10/100/1000) to my computer. Theoretically speaking, I should therefore reach gigabit transfer speeds to my shares, right?

ifconfig output:

Code:

em0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500
		options=42098<VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_MAGIC,VLAN_HWTSO>
		ether 68:05:ca:3e:96:3d
		inet 192.168.0.15 netmask 0xffffff00 broadcast 192.168.0.255
		nd6 options=9<PERFORMNUD,IFDISABLED>
		media: Ethernet 1000baseT (1000baseT <full-duplex>)
		status: active

That sounds about right. You'll never see gigabit speeds. It's really amazing that they work at all.

While the adapter connects to the computer and reports a gigabit between the computer and the device, between adapters the connection is MUCH slower. Even the absolute best powerline adapters fail to achieve their rated speeds under controlled conditions.

Cheers,

so the only way for me to achieve better transfer rates is to physically connect the two devices via Ethernet cable?

You might get better performance with WiFi but a physical ethernet cable is the gold standard.
