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。
Normally, a JIT-related problem warrants a service call to an appropriate IBM support component.
通常，与JIT有关的问题会将一个服务调用授权给一个适当的IBM支持组件。
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。
