Hardware and Performance / How to improve internet speed per connection
« on: June 10, 2024, 05:08:10 pm »
Hello everyone, I'm new to OpnSense and have only used it since a month ago. I like it so far thanks to the friendly UI and the comprehensive features. I feel there's a lot of to learn from it 
I installed OpnSense directly on a mini-PC with 14 cores CPU and plenty of RAM (probably overkill I know), and enabled Zenarmor on the LAN/vLAN interfaces. The inter vLAN speed is ~5gbits/second using iPerf which works for me (and probably have room to tune), but the internet speed is slower than I expected. With the default settings of either speedtest.net or fast.com, the download speed is around 400mbits/s while the upload speeds is 900+mbits/s. After I change the "maximum connection" setting on fast.com from 8 (default value) to 16 connections, I get the expected download speed of 940mbits/s.
Does anyone know how to increase the speed per connection? Is it because my CPU's single core performance is not as good (however the CPU usage is quite low on any core), or there's some settings I set incorrectly? This issue doesn't happen when I use a different router or connect the internet to my PC directly. Thanks for the help in advance!
