switch speed question

[bruce at yoafrica.com (Bruce Grobler)]

Hi,

It depends on how heavily loaded your switch is expected to be, for instance
two machines using the switch will be able to get a full 1Gbps, however
depending on the backplane (switching fabric), it limits how many ports will
receive full 1Gbps when the switch is congested, e.g. a 2 gig backplane
against a 24 gig.

Regards,

Bruce
