Did you check PCI bus bandwidth? That's probably going to be the biggest constraint on "a few 10GBE interfaces" if they all get going full blast. Remember that each packet is going to burn bandwidth twice - once in and once out...
PCIe, x8 or x16, which is serial point to point. http://www.csc.kth.se/~olofh/10G_OSR/10Gbps.pdf 25 Gb/sec across 4x10G ports on higher end but far from topped out hardware. -- Leo Bicknell - bicknell@ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/
