i have serval different Systems running, including an old 3GHz Intel Pentium D-CPU with 2GBytes ECC Memory: 4 Nic, throughput max (so far): 115 MBytes/s at 20k irqs (no polling enabled, no special tweaking) 1 Nic is Broadcom, 1 Nic is Intel Pro1000 Desktop Adapter, the other two Nic are an Intel Pro 1000 Dual Port Server Adapter. Memory is a bit short in this system, but it runs fine.
others Systems p.e. run with Core2Duo 2,66GHz (E7300) another one with a Pentium 2,9GHz (G2020) the last one i wouldn't recommend for high throughput and low latency. the reaction times and the latency rises up fast if the throughput rises or if i add some VPN-Tunnels( AES-256). so i would recommend also the Corei5, the core i3 IMO comes close to a Pentium CPU. imself keep the Celeron CPU's far away from me. except for small embedded systems in the lower range. Corei7 or Xeon is a way to much for my taste and feeling. hth. = = = http://michael-schuh.net/ = = = Projektmanagement - IT-Consulting - Professional Services IT Rev.
