Further results - It looks like in our current configuration we can't get past about 2.8Gb/s. We've reached that at about 600k PPS at about 97% of CPU usage as reported by ESX (might be partially caused our traffic mix - residential broadband, with a skew towards gaming). In theory we should be able to get about 800k PPS, but I suspect that's on basic image (i.e. without MPLS).
