Hi All,
Iam analysing some of Response time degradation Problems in my environment, in execution breakdown I can see

79% network I/O , please let me know what does it indicate here? In most of such Response time degradation problems I can see Network I/O is less.

You can also look at the hotspots for the network as well to get a better view of how it contributed overall. Basically what the page is staying is that it took 21.2s to respond and process, and of that time, 79% of it the time was held in Network I/O.

Network IO can encompass multiple things, SQL queries, webservices, etc. It really depends on the functions, being defined as: "Percentage of measured samples in which the method is actively waiting for native network functions"
