In this blog we describe how we profiled Heron to identify performance limiting components, we highlight the optimizations, and we show how these optimizations improved throughput by 400-500% and reduced latency by 50-60%.
Twitter studied both Twitter users and non-users across five consumer electronics categories, ranging from wide adoption to early adoption, and discovered eight important new insights into technology purchase behavior as it relates to category maturity on Twitter.
Using a second control can be a tempting method of validating experiment results. We explore the statistics underlying usage of a second control, and conclude that this approach is strictly inferior to using a single large control.
We describe our experimental visual analytics approach for funnel analysis, which helps us explore how users interact with the user interfaces and gain new insights for improving user engagement with Twitter.
