Research has shown that most virtual invocations have only a single target for all receiver objects, and JIT compilers can generate more-efficient code for a direct call than for a virtual invocation.
研究表明：大多数虚调用只有一个目标对应于所有的接收方对象，而JIT编译器可以为直接调用生成比虚调用更有效率的代码。
Once the method is compiled, the next call to the method runs the JIT compiled version.
方法编译之后，对方法的下一次调用会运行JIT编译的版本。
However, if a service call to be opened with IBM support, not narrowing down enough to the narrowest possible set of methods and JIT optimizations involved will complicate resolution of a problem.
然而，如果已经使用了IBM的技术支持的服务请求，假设没有将所涉及的方法和JIT优化选项的范围定位到最窄的范围，就可能会使问题的解决方案变得复杂。
As such, the metadata for the object being referenced must be available to both application domains to allow the method call to be JIT-compiled properly.
因此，被引用的对象的元数据必须对于两个应用程序域均可用，以便用JIT正确编译该方法调用。
