Today we talk about that old chestnut (or bugbear, if you like) of the software industry: performance testing. We discussed this subject back in August with Keith Moon, but it's a big topic, so we thought we'd revisit it.
Wolfgang is in the studio talking with Larry Ng. Larry is a senior QA specialist at QA Labs.
Here are a few quotes from today's show:
"When the customer asks us to do performance testing, what they have in mind is usually the user response time and how the system performs under load--as in system resources and database performance. So it's not always easy to define what a 'meaningful result' means--it's not easy to define what measurements we need to gather."
"The bottom line is that when we're doing performance testing, we try to generate the load to the system by whatever means. We don't need to necessarily adhere to business scenarios. We can split it up into multiple scenarios and still generate the same load."
"In terms of metrics, most people want to see a solid result about user response time and system performance--how much CPU got used, is there enough memory to handle the load and so forth."
