Designing for Scalability
I ran across this article yesterday. It is nearly two years old, but the content is still entirely relevant. If you are building a system that needs to scale out to handle a large load, then you’ve probably already read this or something similar…if not, then it is worth your time.
What is the relevance to Load Testing, you ask? In section 5 author, Simon Brown, says”
“… set measurable goals throughout the system, verify and measure the real performance and consider performance at all stages of the project.”
For a project manager, a key part of the job is reducing risk … Continue reading »
New JavaScript optimizer
From a load testing perspective, we are not generally concerned with Javascript performance – since it affects client-side rendering time and therefore has little relationship to load.

Google has a relatively new project, Closure Compiler, that optimizes JavaScript code to reduce size and improve performance.
If you’ve tried the Closure Compiler, give us a shout. We’d love to hear about your results!

Firefox had been open for a few days and currently had 8 tabs open. I am … Continue reading »
