When Configuration Settings from Development Wreak Havoc in Production By Asad Ali As applications are promoted from the development environment to the CI or the QA environment and then into the production environment, it is very common for the configuration settings to be changed as the code is promoted. For example, the settings for the database connection pools are typically lower in development environment than the QA/Load Testing environment. The primary reason for the existence of the configuration setting differences is to enhance application performance. However, occasionally there are instances where the application code is mistakenly promoted into production without changing these settings. In such cases, such promotion of code can cause performance havoc in the production environment. This blog describes one such scenario. During their proof of concept, a... (more)

HTTPS Is Not Faster Than HTTP | @DevOpsSummit #WebPerf #DataCenter

Yes, Lori has been reading the Internet again. And what she's been seeing makes baby Lori angry. It also makes this former test designer and technology editor cry. Really, I weep at both the excuses offered for such testing and the misleading headline. I have read no less than two contrived comparisons of "HTTPS" and "HTTP" in the last two weeks purporting to demonstrate that secure HTTP is inarguably faster than its plaintext counterpart, HTTP. Oh, if only that were true. See, the trick is that both comparisons (and no doubt many more will follow) are comparing secure HTTP/2 wi... (more)

The True Cost of Downtime By Kevin Goldberg Do you know how much your organization risks with every potential outage? Application performance issues can impact away more than revenue, your brand might take a substantial hit as well. Hundreds, thousands of potential customers could take to Facebook, Twitter, Yelp, the App Store and voice their complaints and give poor reviews simply because your app crashed, stalled, or they weren’t able to successfully check out. Unfortunately, application issues are inevitable. Even if your uptime SLA is 99%, your application would still be down ... (more)

Revisiting the Anatomy of HTTP: Part I | @DevOpsSummit #APM #DevOps #WebPerf

Revisiting the Anatomy of HTTP: Part I By Arun Kejariwal and Mehdi Daoudi One of the key driving factors behind the various web/mobile performance initiatives is the fact that end-users’ tolerance for latency has nose-dived. Several studies have been published whereby it has been demonstrated that poor performance routinely impacts the bottom line, viz,. # users, # transactions, etc. Examples studies include this, this and this. There are several sources of performance bottlenecks, viz., but not limited to: Large numbers of redirects Increasing use of images and/or videos without... (more)
