1) do you have KeepAlive on your requests? Does your application load anything into the session the very first time? >What I am seeing is that the very first call ( to bring up the login page )takes 3-4 seconds. The rest of the calls have a normal response time. When you say rest of the calls , do you mean the subsequent calls or the same login calls (in different iterations). Its quite possible that a page has different load times from the rest (you might only have a problem if the same page shows vastly differing load times). Jmeter does not cache anything unless you added the Cache Manager to your test plan

My question is, at what >point does machine resources start to effect test results? The problem could be your client or your server. An easy way to check is run two separate Jmeter instances on two separate client machines with say half the threads on each (so your total load is still 25 threads) at the exact same time. if your response times are bad, then it means your server is overloaded. If they are good , it means that your client is overloaded (there are other ways to check this using network monitoring tools and other os specific perf tools, but the above is the easiest) On Tue, Nov 17, 2009 at 5:29 AM, cmrz <[email protected]> wrote: > > Hi, > > I have a couple of questions . . . > > 1) I am running Jmeter via command prompt.
