Celeron J1900 device can be found for cheap. I saw some wi= th 4 intel Gb NIC.

Looks interesting... I like the SFP+ being there, too.

(Regarding Xilinx ... My focus is on the FPGA. The ARM cores are less inter= esting, other than that the FPGA side can directly access their cache syste= m creating a powerful, fast, coherent autonomous DDR backed memory addressa= ble memeory for packets that does not need processor intervention. But Xili= nx parts are not cheap)

cool. which? ultrascale?

I was looking over
http://cseweb.ucsd.edu/~ssradhak/Papers= /senic-nsdi14.pdf again

How fast can that cpu context switch?
