Thoughts on MySQL optimization [storage engine, index]

For SQL optimization, today we first look at the basic knowledge: ? Storage engines. Understanding the characteristics and applicable scenarios of MySQL’s different storage engines can help you make wise decisions in database design and application development. ? Index, when the table does not have an index, querying the data may be a full table […]

AndroidScreen freeze optimization list smoothness one

The rendering time of lag is as shown below: Caton performance has the following aspects: Network image rendering takes a long time The response of sliding up and down is slow, and the screen may even not move. It takes a lot of time to load and render a new page of data. There is […]

Android performance optimization series apk slimming

Why APK needs to be slimmed down. The larger the APK, the more traffic they will consume during the download and installation process, and the longer the installation waiting time will be; for the product itself, it means that the download conversion rate will be lower (because users have more opportunities to choose among competing […]

Another look at the Glide image loading library from a memory optimization perspective

Front background As a commonly used image loading framework, Glide has a lot of memory optimizations at the framework level. However, as an image framework, ensuring correctness must be the first priority. Therefore, some additional optimizations can be made in appropriate scenarios at the application layer. , of course you need to understand the problems […]
