Re: Load Testing - what to look for and monitor/report

[Dave Watts]

 Anyhow, what I really want to know from you experts is what should I be
 watching and recording during these load tests?

Generally, you're interested in response time and throughput.

 Also should I pair down from a load balanced solution to a single server to
 make it easier to debug log files and track memory etc?

 And then scale up after a specific duration? Or for the second test
 interval?

 I don't have much experience with load testing and just want to make sure
 that this is money well spend in terms of having some actionable data.

It's hard to answer this without more information. What is the goal of
the load test? What kind of actionable data are you looking for?

You can use load tests to answer a couple of different questions.
There are two basic types of load test: performance analysis, and
capacity planning. In a performance analysis test, you're looking for
bottlenecks in your application with the goal of improving application
performance. In a capacity planning test, you're trying to identify
how many users your application can support as it's currently written.
Which one of these are you doing?

Hi Dave,

We're doing performance analysis and looking for bottlenecks and also memory
leaks since we have a lot of application scoped components and large numbers
of objects created per request. That's one of my main concerns actually..
