We broke our own load testing record – yet again!

by | January 22, 2014

At the end of 2012, Apica conducted a massive load test for an election campaign organization. It was the largest load test we ever conducted, surpassing the two million virtual user mark we set earlier that year. The load test clocked in at over 200,000 requests per second for an entire hour. To put this in context, roughly 23,000 Google searches occurred every second at the time.

At the end of 2013, we blew our own record out of the water. After being contracted to conduct a load test for a well known government, we reached over 620,000 requests per second with over 1 million concurrent users. Here’s what the web transaction rate chart looked like for a 30-second sampling interval:


And here’s what the test looked like 5 minutes and 44 seconds in:

All of us at Apica are very excited. We’ve increased our ability to handle traffic by 300% in just one year, and can now accommodate up to >1 million concurrent users and >500,000 requests/second. To put this in perspective, healthcare.gov servers crashed catastrophically back in early October when the site had over 2.3 million total visitors on its launch day, but at any given time there were only 250,000 visitors, much less than 600,000 requests per second.

We’ve said it before, and we’ll say it again – it pays to plan for success!
