Great, bood, bad or terrible performance?
Almost all of the on-board Gigabit Ethernet NICs are very good. They are integrated into the primary chipset - giving them good access to main memory and - reducing the opportunity for vendors to use the cheapest NIC chip. You won't find advanced offload features, but you do get good, solid non-quirky performance. A secondary effect is that there are now very few NIC families, and those vendors are motivated to support/control their drivers. The network device driver challenge of a decade ago, supporting hundreds of designs, is all but gone. > stability issues? Much concern about it's use for clusters?
