White Paper on GA620/GA620T Gigabit Ethernet Card

Performance

Gigabit Ethernet adapters represent the next step in the evolution of

network performance. The widespread adoption of Fast Ethernet at the desktop

has created a bottleneck at the server, specifically at the Server adapter. Some

companies have created Server adapters with multiple 100 Mbps connections,

while others have populated several PCI slots with 100 Mbps adapters to boost

Server bandwidth beyond Fast Ethernet. Gigabit Ethernet delivers performance

beyond these aggregation band -aids, by delivering speeds approaching 1 Gbps

Network Configurations

Due to the fact that Servers benefit most from Gigabit speeds, the adapter

card drivers are optimized for that environment. In most ne tworks, the server

distributes information to multiple clients. For this reason, the driver has been

optimized to perform best in a one-to-many environment. Using the test program

Microsoft’s NTTTCP program. While one is unlikely to see the full capabilities of a Gigabit Ethernet card when tested back- to-back, it is still possible to get a feel for the capabilities of the adapter. File Transfer Another test that does not accurately measure adapter capability is a file transfer.
