344 ; This is the multiplier applied to all client throttles for outgoing UDP network data
345 ; If it is set to 1, then we obey the throttle settings as given to us by the client. If it is set to 3, for example, then we
346 ; multiply that setting by 3 (e.g. if the client gives us a setting of 250 kilobits per second then we
347 ; will actually push down data at a maximum rate of 750 kilobits per second).
348 ;
349 ; In principle, setting a multiplier greater than 1 will allow data to be pushed down to a client much faster
350 ; than its UI allows the setting to go. This may be okay in some situations, such as standalone OpenSim
351 ; applications on a LAN. However, the greater the multipler, the higher the risk of packet drop, resulting
352 ; in symptoms such as missing terrain or objects. A much better solution is to change the client UI to allow
353 ; higher network bandwidth settings directly, though this isn't always possible.
354 ;
355 ; Currently this setting is 2 by default because we currently send much more texture data than is strictly
356 ; necessary. A setting of 1 could result in slow texture transfer. This will be fixed when the transfer
