g an email message a text file a jpeg file a gif file an xml file etc upon making the request a determination may be made to determine the effective latency between client system 2 and each of acceleration servers 510 in addition a determination may be made as to which of content servers 515 have the requested content subsequently the effective latencies between each of acceleration servers 510 and each of content servers 515 which contain the requested content may be determined based on the effective latencies a determination is made as to which acceleration server content server combination provides client system 2 with the fastest transfer rate for example it may be determined that the effective latency between client system 2 and acceleration server 1 is lowest however the latency between acceleration server 1 and each of content servers 515 may be much higher than the effective latency between acceleration server 2 and each of content servers 515 accordingly even though the effective latency between client system 2 and acceleration server 1 is the lowest that effective latency would be outweighed by acceleration server 1 39 s high effective latency with content servers 515 hence acceleration server 2 would be selected along with content server 515 with the lowest effective latency with acceleration server 2 thus the highest transfer rate for client system 2 of.
