What kind of hardware is needed to efficiently handle 45mbps of traffic that will burst up to 100mbps? We are getting a 100mbps ethernet feed from our new provider and plan to use RouterOS 2.8 on a Pentium 4 Hyperthreading 800mhz bus system as our Router. It will have to handle 45mbps continuously with bursting to 100mbps, mostly it will just be interfacing traffic between the provided ethernet connection and our ethernet switched network, with static routes setup for blocks of ips assigned to servers to minimize ARP usage and basic firewalling including ports 135-139 and SNMP blocking.
We currently do this with our Cisco 7206 but wish to move towards a more generic solution with less expensive gigabit interfaces.
Our concern is the ability for the software to handle that # of packets. From what I understand since it has to be processed by the Processor it could cause a bottleneck issue. What have you guys been able to continuously push and on what hardware?
Also does the router need any more than 512 megs of ram?
