See this page for an explanation of "sharing"

"mixed" refers compiled vs. interpreted code. --编译还是解释

Java command options
-Xmixed tells the jvm to both interpret and compile code
-Xint tells the jvm to only interpret code
-Xcomp tells the jvm to only compile code
-XX:CompileThreshold=nn number of method executions before a method is compiled
