This particular server is colocated and the bandwidth average is =20 2.35mbps while the 95th is 3.7mbps. I don't want my clients to have to compete for bandwidth - if 1000 =20 users share a 3mbps fixed pipe, they will each get 3k/sec -. Rather I =20 want to guarantee a fixed output for each client. This ensures =20 adequate speed for everyone AND flattens out my peaks.
