Both maxrate and minrate are expressed in bytes per second, as are the 
client rates.
As far as I know (I'm almost but not 100% sure on this, if I'm wrong 
somsone please correct me), the maxrate is more important than the 
minrate. The maxrate of the server is compared to the client's rate and 
the lowest value of them is the maximum number of bytes per second the 
server will send to the client. The minrate is (I think) only used at 
connection time. If a client advertises a lower rate than the sv_minrate 
the client won't be allowed to connect, is has no impact on performance 
AFAIK. If you want to deny slow clients you better experiment with 
sv_maxping and sv_minping. I also think setting your maxrate to value 
higher than your bandwidth is a killer for your clients.

My 16 public player Spearhead server's got a full 100mbit/sec 
connection, minping 0, maxping 500, minrate 0, maxrate 7000. The clients 
do experience lag on some maps but that is solely caused by hardware 
being inadequate or the Spearhead server consuming too many resources. I 
even had to shut down the "old" MOHAA server because of the shortage in 
CPU power.
The 7000 bytes/sec rate is more than enough for good gameplay. Most of 
the times the traffic will indeed be around 2-3kbyte/sec but it does 
have "spikes", sudden bursts of data transfer.

Hope this helps,

Eric.
