Network Visibility can pinpoint performance bottlenecks down to a specific tier, node, or network path. Either of these bottlenecks can slow down an application significantly:

• Application/Network bottlenecks Many bottlenecks identified as "network issues" actually have their root cause defined by how an application or a server uses network resources. Network Visibility can detect many different types of app/network bottlenecks, as well as bottlenecks due to TCP socket issues on a specific node.
• Network bottlenecks A network bottleneck indicates that a specific section of the network cannot process the application loads between the source and destination nodes. Symptoms of a network bottleneck include a high rate of packet loss or high round-trip times (RTTs) between two nodes.
