I recently upgraded my home Internet from Spectrum Ultra (500/20) to TDS Fiber Gigabit (1000/1000). However, when running speed tests on the new circuit I noticed that I was consistently getting speeds SLOWER than my Spectrum Circuit. I was getting around 250-300mbps.
This ended up being a configuration issue with my Ubiquiti EdgeRouter PRO-8, which is definitely capable of delivering gigabit speeds!
The very first things I checked, were to ensure I was running the latest code (v2.0.9-hotfix.5 at this time) and that hardware offloading was ENABLED:
$ configure
#set system offload hwnat disable
#set system offload ipsec enable
#set system offload ipv4 bonding enable
#set system offload ipv4 disable-flow-flushing-upon-fib-changes
#set system offload ipv4 forwarding enable
#set system offload ipv4 gre enable
#set system offload ipv4 pppoe enable
#set system offload ipv4 table-size 65536
#set system offload ipv4 vlan enable
#set system offload ipv6 bonding enable
#set system offload ipv6 forwarding enable
#set system offload ipv6 pppoe disable
#set system offload ipv6 table-size 65536
#set system offload ipv6 vlan enable
#commitI was still seeing the issue, still had slow speeds. But, I also noticed in the GUI that when I was running my speed tests the CPU was maxing out at 100%. I jumped down to the CLI and ran “top”, to see what was pegging the CPU.
The ksoftirqd process was pegging the CPU on the EdgeRouter. This lead me to this post, which reminded me that I had played with Netflow a few years back.
