Improve the Link Speed

For SNA/APPC. Throughput is dictated by the speed of the slowest link when using a gateway, bridge, or router. Faster links provide faster performance. The link with the best performance is the Token Ring (local Token Rings only—remote controllers are significantly slower), then Coax (locally connected), then SDLC (or any remote cluster controller). 3174-attached Token Rings normally produce higher throughput than 37xx Token Ring links.
