Centrally hosted and globally used applications don’t always deliver the satisfied user experience. Some people may argue; “don’t worry, let’s increase the bandwidth to solve our performance problem... simple!”. Based on my experience, the biggest proportion of WAN performance issues is not related to a shortage of bandwidth.
In one of my previous projects, I was involved in a performance-related fire-fighting task. Some business customers from abroad claimed to be having a very bad user experience. The initial analysis done by the responsible application manager demonstrated that this problem could not be reproduced and that all application components including infrastructure and database were delivering excellent response times. However, the business manager escalated this issue and increased the pressure on the IT department.

Based on my experience the biggest proportion of WAN performance issues is not related to a shortage of bandwidth. CY from Asia for instance, the login took up to 50 requests x 300ms latency 15 seconds longer.

The moral of the story is,hztrfff never underestimate the performance impact of your network. Make web page design analysis and real user monitoring part of your application delivery pipeline to keep your user community satisfied.
