David at Rimuhosting, where I work, has put together a nice script that automates benchmarking with httperf. I couldn't resist testing it out on Something Emporium. Here's the pretty graph:
The y axis measures average response rate, in responses per second. The x axis is the request rate, from 2 to 40 requests per second. Perfect performance is the line
y = x, because (unless you're psychic) you can only respond to requests you receive. So, I'm quite pleased with these results.
Can you spot the outlier in the above graph?
