idea文件介绍

D:\Program Files\JetBrains\IntelliJ IDEA 2018.3.3
bin 目录是一些执行和配置相关包
help 目录帮助文档手册
jre64 目录是jre运行支持
lib 目录是运行用到的jar包
licenese 目录是许可协议
plugins 目录是插件
redist 目录是一些杂项

C:\Users\Administrator\.IntelliJIdea2018.3
config是你对idea的配置的文件这个文件保存好，假如其他电脑安装idea，启动的时候可以选择导入你的这个config这样省得再重复配置了；
system目录是一些系统缓存文件，日志文件，临时文件，索引文件，包括本地历史文件等等，假如idea遇到运行奇葩问题，请把system文件删除，大多数情况能解决问题；

idea优化配置

找到idea安装的bin目录：
D:\Program Files\JetBrains\IntelliJ IDEA 2018.3.3\bin
打开idea.exe.vmoptions这个文件：根据电脑配置，适当提高配置参数
第一个-Xms是最小启动内存参数 
第二个-Xmx是最大运行内存参数
第三个-XX:ReservedCodeCacheSize保留代码占用的内存容量参数

默认：
-Xms128m
-Xmx750m
-XX:ReservedCodeCacheSize=240m

例如：16G内存
-Xms1000m
-Xmx2000m
-XX:ReservedCodeCacheSize=500m
