You can fine tune several Webpack plugins to make your bundle as small as it can is for your specific application. However there is a few things you can does for pretty much every application to make it smaller and run faster. In this lesson we'll combine several webpack plugins to optimize things for a React application (this is also applicable F or non-react applications as well).First we need to modify the Prod scripts from:" Build:prod " " Webpack--env.prod-p ",To:" Build:prod " " Webpack--e

After a great deal of hard work, I finally finished reading the fifth chapter of this book. I was deeply touched by the fact that I had to learn about this in the book. This is because I read and practice it. Recently, I have completed a script to implement the whole process from registering personal data, opening an account for a purchased product, and making a payment. In fact, this script is not for any performance test, but I learned a lot to so

Author: Tony Qu Because 2.0 of NPOI 95% beta 2 does not use XmlSerializer for serialization, the experiment shows that the performance improvement is almost 10-20 times. Of course, there are many reasons to kill XmlSerializer. First, XmlSerializer has many restrictions. NPOI is the basic library of NPOI. openXmlFormats cannot generate the assembly of XmlSerializer in advance. This is a
