Because our application is running on the Liferay application server, some optimizations for the server are of course our first thought.
We have done a lot of testing before, because Liferay will have css-fast-load, and js-fast-load, these parameters will be a number of CSS files or several JS files merged into a single large file, which can significantly reduce the number of network IO overhead, We developed in order to facilitate debugging, of course, we need to let these files are not merged, so we can easily debug, but in the demo server, we obviously still do they merge, so we have on the portal-ext.properties on the following configuration:
As shown in the figure, it turns theme,javascript these fast load from false to true.
Of course, we use the ext-all-debug.js in the development phase, we will use Ext-all.js instead of ext-all-debug.js in order to improve the performance.
