Assessing MySQL Performance Amongst AWS Options - Part Two
See part one of this series here. This post is part two of my series “Assessing MySQL Performance Amongst AWS Options”, taking a look at how current Amazon RDS services – Amazon Aurora and Amazon RDS for MySQL – compare with Percona Server with InnoDB and RocksDB engines on EC2 instances. This time around, I am reviewing the total cost of one test run for each database as well as seeing which data
Busting Android performance myths
Over the years, several myths have emerged about performance on Android. While some myths can be entertaining or amusing, being sent in the wrong direction when looking to create performant Android apps is no fun. In this blog post, in the spirit of MythBusters, we’re going to test these myths. For our myth-busting, we use real-world examples and tools that you can use. We focus on dominant use pa
gRPC performance improvements in .NET 5 - .NET Blog
gRPC is a modern open source remote procedure call framework. There are many exciting features in gRPC: real-time streaming, end-to-end code generation, and great cross-platform support to name a few. The most exciting to me, and consistently mentioned by developers who are interested in gRPC, is performance. Last year Microsoft contributed a new implementation of gRPC for .NET to the CNCF. Built

A lot of people use React context as some kinds of build-in redux. Jack is one of them. Jack combined all global state to get a big object to get a ‘single source of data’ and put it into a provider. Then he went to a child component, call useContext and pick properties from the context. Everything seems worked fine until one day he found the app is too slow to use. A Bad Example Consider the foll

CORS is a necessity for many APIs, but basic configurations can create a huge number of extra requests, slowing down every browser API client, and sending unnecessary traffic to your backend. This can be a problem with a traditional API, but becomes a much larger issue with serverless platforms, where your billing is often directly tied to the number of requests received, so this can easily double
