This document provides general information about maximum network throughput. This information applies to most any system, regardless of operating system and levels.
Throughput over a network can usually be expected to reach saturation at around 80 percent of its rated capacity. This leads to the following maximum throughputs that can be obtained for given networks:
4 Mb Token ring - 0.4 MB/sec 10 Mb Ethernet - 1.0 MB/sec 16 Mb Token ring - 1.6 MB/sec 25 Mb ATM - 2.5 MB/sec 100 Mb Ethernet - 10.0 MB/sec 100 Mb FDDI - 10.0 MB/sec 155 Mb ATM - 15.5 MB/sec Gb Ethernet = 100 MB/sec
The numbers provided do not reflect other traffic over shared lines, broadcast traffic, traffic from other applications, routing delays, switching delays, half-duplex settings or any of the many other factors which can decrease the throughput of a network.
These numbers do not factor in disk read times, tape write times,
application overhead, system load, operating system overhead,
or any other non-network factor. The information in this document
is not intended to be a guarantee of performance, nor is it intended
to replace actual testing in your environment.
