Earlier today I had to find out what the capacity of a soekris net4801 running openwrt.
Using a fairly normal rule set, it can forward 51.8 Mbits/sec which is alright for a 266 MHz processor.
Sadly for me, we’ll be getting a 100 Mbit fiber optic connection at work in a few months, so I guess I’ll have to move to a net5501 unit in order to max out the connection.
