NGINX and HAProxy: Testing User Experience in the Cloud
NGINX and HAProxy: Testing User Experience in the Cloud Many performance benchmarks measure peak throughput or requests per second (RPS), but those metrics can oversimplify the performance story at real‑world sites. Few organizations run their services at or near peak throughput, where a 10% change in performance either way can make a significant difference. The throughput or RPS a site requires is not infinite, but is fixed by external factors like the number of concurrent users they have to serve and the activity level of each user. In the end, what matters most is that your users receive the best level of service. End users don’t care how many other people are visiting your site. They just care about the service they receive and don’t excuse poor performance because the system is overloaded. This leads us to the observation that what [ more… ]
