       I got my hands on a second hand Fitlet2 which comes with an Atom E3950, 8GB of RAM, 64G of M2.SATA, 2x i211 RJ45 and 1x i210 SFP cage, running ~11 Watts.I took it out for a spin on https://ipng.ch/s/articles/2023/02/12/fitlet2.html

       With some care on the VPP configuration (notably RX/TX descriptors), this unit can handle L2XC at (almost) line rate in both directions (2.94Mpps out a theoretical 2.97Mpps), with one VPP worker thread, which it not just good, it’s Good Enough™, at which time there is still plenty of headroom on the CPU, as the Atom E3950 has 4 cores.

       In IPv4 routing, using two VPP worker threads, and 2 RX/TX queues on each NIC, the machine keeps up with 64 byte traffic in both directions (ie 2.97Mpps), again with compute power to spare, and while using only two out of four CPU cores on the Atom E3950.

       For a $400,- machine that draws close to 11 Watts fully loaded, and sporting 8GB (at a max of 16GB) this Fitlet2 is a gem: it will easily keep up 3x 1Gbit in a production environment, while carrying multiple full BGP tables (900K IPv4 and 170K IPv6), with room to spare. It’s a classy little machine!
