We'll soon be buying 2 10Gbit servers for Wowza streaming, however we're not sure what kind of CPU power we need.
The servers we will be buying are Dell PowerEdge R510's with Broadcom NetXtreme II 57711 10Gbit NIC's. The NIC makes use of TCP Offload Engine which should help reduce the CPU load.
We currently have the Intel Xeon E5620 CPU in mind for the server. Does anyone have experience with streaming 10Gbit (8-9 Gbit minus overhead) with this CPU or similar? Will this one CPU cut it, or will we need 2 of those?
