Hi Nagar, Thanks for your response and time. Yes a good question. (a) The short tasks to measure the response time itself after applying the division of load and before. (b) The long tasks means HPC tasks to measure the load signal after applying the division of load and before. I have run it for 600s, 1000s, and 1500s. The both these tests were successful. What I want to document is some standard tests just like using lmbench and re-aim-7. I will go through your web site as well Thanks Sena Seneviratne Computer Engineering Lab School of Electrical and Information Engineering Sydney University Australia At 12:08 AM 6/19/2006 -0400, you wrote: >sena seneviratne wrote: > >>In fact my question in the post was about performance testing after the >>changes being done. >> >>--2) Now about the tests >>--As I have documented all this yet need to perform some standard tests >>for the sake of completion. >>--What tests should I carry out to prove that the system is still intact? > > >>--Please tell me whether the below is correct? >> >>--(a) As suggested by the http://kernel-perf.sourceforge.net/ the lmbench >>and re-aim-7 test packages can be used to test the ----performance of the >>kernel before making changes and after.
