Only getting 12MBps

[bradenterpstra]

I have a gigabit card in my laptop, a gigabit router, a gigabit switch, a gigabit card in my FreeNAS, and Cat5e wiring it all together(no wifi). How come I am only getting 12mbps(100mbps)? Shouldn't I be getting around 100MBps transfer speeds even with a HDD?

Have you verified that all the interfaces are actually (auto)configured to run at gigabit speed?

There are a number of unknowns the information that you have provided.Your results seem rather low.

• What type of laptop? What is the operating system? Are you sure that it has a GigE NIC? Are the drivers up to date?
• What type of router? Are there different subnets involved? Is your router also acting as a firewall?
• What type of switch? Is it managed? Using VLANs?
• How are you testing?

The more information the better.

For example, in my case I have:

• Router/Firewall - pfSense 2.4.4-RELEASE-p3 (Intel Core i5-2540M CPU @ 2.60GHz, 4 GB RAM) with VLANs and pfBlockerNG
• Switch (core) - Ubiquiti UniFi US-24, CAT5e
• Switch (local) - Ubiquiti UniFi US-8, CAT5e
• Laptop - Lenovo L340 (Intel Core i7-9750H CPU @ 2.60GHz × 6, 8GB RAM), Linux Mint 19.3
• FreeNAS config (see my signature)

My results using iperf:

I figured it out. I thought my router was gigabit, but it is not. It is from 2008. My old router was gigabit, but it broke the other day. Capacitor fried. So when I get my replacement router, that will be gigabit and I will check if that fixes it. Thanks for the help.
