1. IDEA memory optimization
First look at the configuration of your machine itself and configure it.
\IntelliJ IDEA 8\bin\idea.exe.vmoptions
----------- ------------------------------
-Xms256m
-Xmx384m
-XX:MaxPermSize=128m
-XX:NewRatio=4
-Xss128k
-Dsun .awt.keepWorkingSetOnMinimize=true
-server

-Xms256m Set the initial memory number, you need to set a reasonable value, increasing the value can improve the startup speed of Java programs. If your memory is large enough, such as 2G, you can set it to 400m.
-Xmx384m sets the maximum number of memory, increasing this value can reduce the frequency of memory Garage collection and improve program performance.
-Dsun.awt.keepWorkingSetOnMinimize=true allows IDEA to keep the occupied memory when it is minimized to the taskbar. When you return to IDEA, it can be displayed quickly instead of gradually showing the entire interface from the gray and white interface, speeding up the recovery. The speed of the original interface.
-server controls the way the memory garage is collected so that you don't have to spend a minute or two waiting for the memory garage to be collected.

2. Optimize file saving and project loading

Cancel "Synchronize file on frame activation" (synchronize file function, consider as appropriate Can not cancel)
cancel the selection of "Save files on framedeactivation"
At the same time, we select "Save files automatically", and set it to 30 seconds, so that IDEA can still keep the file automatically, so you need to press Ctrl+S to save the file every time you switch.

In Settings->Appearance, check Override default fonts by (not recommended), set Name:NSimSun, Size:12

IntelliJ IDEA does not support hot publishing, it is a waste of time and troublesome to restart the container just because we change a page. We solved this problem by changing the directory. Right-click on "AJAX", select "Module settings"



to go here, you will find a Web Facet Exploede Directory, and then we change this directory to point to the Web and node of the current project


*: Note that Exclude from module content is unchecked , otherwise the webroot will disappear

Then we start the container, edit the page casually, then click refresh, and find that the page can be displayed immediately
