The initial stress test went well. I was able to get over 1100 connections to each server. According to the test tool, I generated almost 300 requests per second.
One thing that I don't like about performance numbers is the vast quantity of them! I need to find more time to research the particular items to record to ensure that I am watching the right things. So, while the test was running, I fired up the browser and navigated to the site being tested. I did not notice any difference. WOO HOO!!!!
For those interested, the servers each reported an average of 175 requests executed per second, which exceeds the 300 the clients reported. During the 15 minute test, 266,000 requests were issued with 2400 failed connections. (This is less than 1%, so we will most likely not follow-up until later.)
The performance is deemed acceptable, so now we push forward with a “beta” roll-out starting April 1st. I have a few parts to create, so it's off to the SDK.
