Data center optimization has always played an important role at Meta. By optimizing our data centers’ environmental controls, we can reduce our environmental impact  while ensuring that people can always depend on our products. With most other complex systems, optimization of energy consumption is a trial-and-error process. But experimenting on any component of a live… Continue reading How thermal simulation helps optimize Meta’s data centers

We’ve open-sourced MemLab, a JavaScript memory testing framework that automates memory leak detection. Finding and addressing the root cause of memory leaks is important for delivering a quality user experience on web applications. MemLab has helped engineers and developers at Meta improve user experience and make significant improvements in memory optimization. We hope it will… Continue reading MemLab: An open source framework for finding JavaScript memory leaks

What the research is: The continued emergence of large social network applications has introduced a scale of data and query volume that challenges the limits of existing data stores. However, few benchmarks accurately simulate these request patterns, leaving researchers in short supply of tools to evaluate and improve upon these systems.  To address this issue,… Continue reading Open-sourcing TAOBench: An end-to-end social network benchmark

Meta’s overall network usage and traffic volume has increased as we’ve continued to add new services.
