Why do companies spend hundreds of dollars or more on e.g. Cisco routers?
When many high-end home routers for around $100 able to run e.g. DD-WRT have the same or better feature sets, similar or more powerful processors and the same or more memory?
Firstly, it depends how you define "memory". Flash is generally comparable in the two classes of device - after all, both perform similar functions and the Linux-based devices tend to be slightly more bloated since they are based on a generic system rather than built from the ground up for a specific purpose as in the case of IOS. RAM on the other hand tends to be far more generous on enterprise devices.
Secondly, although the processor on the best home routers are comparable to those on the enterprise routers it is also doing all the work. A home router is basically a low-powered computer with a couple of network interfaces. All packet processing is done in software. In contrast the enterprise routers have extensive additional hardware in place to route packets between interfaces without the intervention of the main processor.
This hardware is orders of magnitude faster than packet processing in software. The actual processor is only used for setting up the routing table and running routing protocols, providing a management interface and possibly routing a few odd packets that the hardware is unable to route by itself (usually because of some added service provided by the router). In other words, the processor never even sees 99% of the router's workload.
