Xeon may work in multi-CPU servers.
Speaking of routers, you have multicore (2CPU x 4cores = 8cores)
machine with 1-2-3 NIC's, and can't load other cores in CPU
(earlier versions before FBSD 8.x).

You need NIC with MSI (Interrupt Moderation) for better performance.

1. What kind of traffic did you expect?
2. What flow bit per seconds did you expect?

I  have PPPoE concentrator based on S3000AHV motherboard with EXPI9400
and EXPI9402 NIC's and Core2Quad Q6600 CPU and FreeBSD 7.2.
This  router  may handle about 150k pps and 1Gbps for one direction of
internet traffic.
Do you need core i5/7 ?
