现象

idea 启动并且点击某个菜单之后一点反应也没有,点击关闭也关闭不掉,查看日志报错如下:

➜  bin 2021-04-30 00:20:31,777 [ 317987]   WARN - .diagnostic.PerformanceWatcher - UI was frozen for 5750ms, details saved to /home/zeek/.cache/JetBrains/IntelliJIdea2020.3/log/threadDumps-freeze-20210430-002031-IU-203.7148.57-RandomAccessFile.readBytes-5sec

在最开始的时候就比较严重,具体原因也不知道是啥。

处理步骤

首先因为我用的是LInux操作系统,jdk默认安装的是openjdk 11,一般来讲openjdk没有oracle jdk稳定,并且openjdk 11 太新了,于是九江操作系统的默认jdk换成了oracle jdk 9版本。

➜  bin java -version
Picked up _JAVA_OPTIONS: -Dawt.useSystemAAFontSettings=on -Dswing.aatext=true
java version "9.0.1"
Java(TM) SE Runtime Environment (build 9.0.1+11)
Java HotSpot(TM) 64-Bit Server VM (build 9.0.1+11, mixed mode)

其次,由于idea 默认给程序使用的内存是700m左右,内存不足也可能导致idea 出现上面情况。于是将idea的运行内存调整为2G,配置文件为idea安装目录/bin/idea64.vmoptions,配置内容如下(只修改了-Xms 和-Xmx的大小):

-Xms512m
-Xmx2048m
-XX:ReservedCodeCacheSize=512m
-XX:+UseConcMarkSweepGC
-XX:SoftRefLRUPolicyMSPerMB=50
-XX:CICompilerCount=2
-XX:+HeapDumpOnOutOfMemoryError
-XX:-OmitStackTraceInFastThrow
-ea
-Dsun.io.useCanonCaches=false
-Djdk.http.auth.tunneling.disabledSchemes=""
-Djdk.attach.allowAttachSelf=true
-Djdk.module.illegalAccess.silent=true
-Dkotlinx.coroutines.debug=off
-Dsun.tools.attach.tmp.only=true

最后在禁用掉自己平时用不到的一些插件。

经过上面三个步骤之后,idea卡顿的现象就不是那么明显了(肉眼不可见)。
