Bandwidth at Non-HQ SitesBandwidth at Non-HQ Sites

Globally, only 12% of respondents have links with bandwidths that are less than 10 Mbps, and 25% have more than 100 Mbps links. In developing countries, access-site bandwidth is 2 Mbps.

Response Times Vary With DistanceResponse Times Vary With Distance

TCP application responses times have a variation of 200%, depending on the distance between sites. As the distance increases, the problem gets worse.

Infrastructure Affects Response TimesInfrastructure Affects Response Times

Inconsistency in application response times depends on network infrastructure. In the Middle East and parts of Asia, conductivity makes matters worse, resulting in response times as high as 153% and an average application response time of one second.
