最近我的idea异常卡顿，一顿谷歌查找后，解决。如下1.调整idea的JVM内存 Help->EditcustomVMOptions-Xms2048m-Xmx2048m-XX:ReservedCodeCacheSize=512m-XX:+IgnoreUnrecognizedVMOptions-XX:+UseG1GC-XX:SoftRefLRUPolicyMSPerMB=50-XX:+UseStringDeduplication-XX:AutoBoxC

备份一下studio64.exe.vmoptions写法：-Xms2g-Xmx16g-XX:ReservedCodeCacheSize=2g-XX:+IgnoreUnrecognizedVMOptions-XX:+UseG1GC-XX:SoftRefLRUPolicyMSPerMB=100-XX:CICompilerCount=2-XX:+HeapDumpOnOutOfMemoryError-XX:-OmitStackTraceInFastThrow-da-Djna.nosys=t

然后把下边的数据替换：原始数据：-Xms128m-Xmx1536m-XX:ReservedCodeCacheSize=512m-XX:+IgnoreUnrecognizedVMOptions-XX:+UseG1GC-XX:SoftRefLRUPolicyMSPerMB=50-XX:CICompilerCount=2-XX:+HeapDumpOnOutOfMemoryError-XX:-OmitStackTraceInFastThrow-ea-Dsun.io.us
