Slow and underperforming applications can create many issues throughout an organisation. This can appear as idle time while users wait for files and documents to cross a network, or frustrating e-commerce customers when they are trying to complete their Internet shopping baskets.

Eliminating performance issues is all about identifying and removing bottlenecks, whether they are physical constraints, or protocol and application limitations. These bottlenecks are generally found in two main areas of the network - the Wide Area Network (WAN) and the Data Centre.
