Generic TCP Protocol Session Delays
The Generic TCP Session Delay exceeds the critical value set in Expert Thresholds. The "session delay" metric combines network latency (i.e., the time spent waiting for data to traverse the network) and application processing time (i.e., the time spent waiting for the server or application to respond to a request). Generic TCP Application Processing Time is tracked with a separate Expert Threshold.
Possible reasons for this event:
There is some problem with the application at either end, either in a station/device, or its configuration. Perhaps hardware is overloaded with disk I/0 requests, or some other system component (for example, the CPU or NIC) is too slow given the traffic it is expected to handle.
The network is slow. You should look for problems with the network. Do you have enough bandwidth between the application server and the clients that use it? Are the routers between the systems configured correctly? Are the MTUs along the route optimized and compatible?
