Rate presets

There are several rate presets included with all released versions of Red Faction. All presets have corresponding value in bytes/sec. These presets can be used in place of an integer when issuing the "rate" console command.

Built-in presets

 * Modem - 2600 bytes/sec
 * ISDN - 5000 bytes/sec
 * Cable - 15000 bytes/sec
 * T1 - 200000 bytes/sec
 * LAN - 200000 bytes/sec

Arbitrary rate specification
It is possible to specify datarate values from 1 byte/sec up to 1569325055 bytes/sec. It seems as if both very low and very high settings are ignored. (Ex: Setting a server's datarate to 1 will not lag out the players)

Good practice in rate selection
Here is an excerpt from a piece written by digital_ruler about how to choose rate wisely:

Server operators should also keep in mind that if the bandwidth is available, they should go for the T1 rate preset. This applies only to those who are hosting servers on dedicated boxes with dedicated internet lines.
