Mac IDEA佔用CPU過高400%

先設置idea的緩存大小和緩存回收

-Xms1024m
-Xmx2048m
-XX:MaxPermSize=512m
-XX:+UseCodeCacheFlushing
-XX:ReservedCodeCacheSize=256m
-XX:+UseCompressedOops
-Dfile.encoding=UTF-8
-XX:+UseConcMarkSweepGC
-XX:SoftRefLRUPolicyMSPerMB=50
-ea
-XX:CICompilerCount=2
-Dsun.io.useCanonPrefixCache=false
-Djava.net.preferIPv4Stack=true
-Djdk.http.auth.tunneling.disabledSchemes=""
-XX:+HeapDumpOnOutOfMemoryError
-XX:-OmitStackTraceInFastThrow
-Djdk.attach.allowAttachSelf
-Xverify:none

-XX:ErrorFile=$USER_HOME/java_error_in_idea_%p.log
-XX:HeapDumpPath=$USER_HOME/java_error_in_idea.hprof

2、再關閉代碼檢查，減少性能消耗，取消所有的勾選，點擊Apply,點擊OK
