> The problem is usually not the software, but the hardware.
It's both. The hardware is slow and the software (in the cases you mentioned, the Linux network stack) is slow and inefficient.
The ERL uses hardware acceleration to avoid all this. It's capable of routing 1M PPS and the latest beta build does this with PPPoE as well. (In other words, it'll support Google Fiber connections well, for the lucky few.)
