Loadrunner Analysis Response times in summary and Avg.transaction response time graph

In loadrunner analysis file, we see response times in two areas.

1. Summary report 2. Avg. transaction response time graph.

But if we observe Min,Max,Avg value in both sheets it differs. Don't confuse and Tense.Here is the reason why?

Summary report publishes exact response times and Avg.transaction response time graph plots a graph and below table based on granularity.The more granules , the accurate the graph shows. Below table is based on the graph values. it caluculates Max,min,Avg,std.dev etc. Hope it clears.

Web page performance improvement at no cost

What does performance of an application means to us ? Primarily we look at responsiveness.Do you really care about End to End performance of an application or server performance.

Though server performance is a major impact,we also need to look at web page performance as well. The reason is most of the web developer does not look carefully into optimisation of client side scripts,CSS files e.t.c There are many open source tools which can help much in such cases. For example - Yslow, Fiddler e.tc.

Analysis failed to analyze result directory for .lrr file

Analysis failed to analyze result directory for .lrr file . If any time faced this kids of issues, please have a look at the error log which is generated while generating the analysis file. It clearly mentions what is the exact error . In one instance we received the error such as the Stop_time is 0.

For such a case the solution is open the .lrr file with notepad and add the Stop_time={somevalue here - it is the elapsed time of the test = start_time+time run in seconds}
Start_time=************
Daylight_Bias= *********
Stop_time= ********
Hope this solution is useful
