通常服务器同时与多个用户连接,用户之间共享带宽.如果N个用户的优先级都相同,那么每个用户连接到该服务器上的实际带宽就是服务器带宽的N分之一.可以想象,如果用户数目较多,则每个用户只能占有可怜的一点带宽,下载将会是个漫长的过程. -Usually the server with multiple users simultaneously connected users share the bandwidth, if N users have the same priority level, each user connects to the server, the server' s actual bandwidth is the bandwidth of N one can imagine, if large number of users, each user can only hold the poor little bandwidth to download would be a long process.
