What are quality gates? How to use quality gates to deliver better software at speed and scale

Dynatrace

Quality gates after load/performance testing Teams can use quality gates to evaluate performance metrics. Before a new version of the application is deployed, the software is subject to a series of load tests that evaluate capacity and performance under a series of simulated traffic and application demands.

The Three Cs: Concatenate, Compress, Cache

CSS Wizardry

In one test, I concatenated it all into one big file, and the other had the library split into 12 files. Read the complete test methodology. Plotted on the same horizontal axis of 1.6s, the waterfalls speak for themselves: 201ms of cumulative latency; 109ms of cumulative download. This will be referred to as css_time.

The Speed of Time

Brendan Gregg

A Cassandra database cluster had switched to Ubuntu and noticed write latency increased by over 30%. Measuring the speed of time Is there already a microbenchmark for os::javaTimeMillis()? There's also a test and println() in the loop to, hopefully, convince the compiler not to optimize-out an otherwise empty loop.
