Server Response Time

The Server Response Time report shows the amount of time a server takes to start responding to a request made by a client.

Tip: When viewing the Server Response Time data in tabular format, the bottom row of the table lists Average/Total statistics for each column. However, the Average/Total statistics are calculated from the Mean values. For example, the Average/Total value for the Min column is actually the minimum of the values in the Mean column - not the average value of the Min column.

This value can be affected by server speed, application design, and volume of requests.

Look for	Might Indicate
Server Response Time increases while the number of observations increases, then look for increases in the following metrics during the same period: Data volumes Data Transfer Time TCP sessions that are open	Strong indication that the server is overloaded.
Server Connection Time increases while the number of observations decreases	Check whether other applications running on this server are monitored by the management console. If so, check for increased observations that correspond to increased Server Response Times for these applications to identify the culprit application process or processes on the server.
No other monitored applications on the server and the number of observations decreases while the Server Response Time increases	Another application might be affecting the Server Response Time; for example, a backup program running on the server can increase response times for concurrently active applications. Check for patterns of increases in Server Response Time and decreases in observations over time and, if necessary, contact other operations teams or use a network protocol analyzer to determine what application running on the server is causing the increase in Server Response Time.
High Server Response Times	One of the following problems with a server: Inadequate processing power Insufficient available memory Slow hard drives Hanging processes Misconfigured NIC settings Presence of poorly written applications, such as database lookups that use large queries or poor indexing
Server Response Time varies consistently	Large periodic data volumes.
Applications send a response to indicate work has started immediately after receipt of a request and Server Response Time is always low	Actual delay in the user experience is exposed in the data transfer rate component.
