Production slower than live. How to isolate the problem?
We have a problem, When we run our ecommerce application on test server it runs faster than Production server. Developers says its problem with server(IIS/JRUN/SQL), whereas Webmasters says code should be optimised.
To isolate the problem, I have recorded scripts, for Test server as well as production server and i am running these scripts for a single user for each script, and starting it same time.
I am viewing the results in scenario execution report thru LR Analysis. and calculating the difference. (results shows Test server is faster than production)
My question is that how can isolate the problem for IIS, SQL server and JRUN?
I told developers to create pages which will only access IIS, SQL and JRUN seperately, for both the servers and then i will run and analyse the test.
