低编译开销更容易被反复执行热代码带来的性能优势掩盖。
Low compilation overhead is maintained that can be more easily hidden behind the performance benefit from repeatedly executing the hot code.
设计这种交换机很有挑战性，需要考虑几个因素：高可靠性、无停机时间(热代码升级)、大规模并发性。
The design considerations for switches like these are challenging: extreme reliability, no downtime (hot code upgrades), and massive concurrency.
当在同一个机器上安装时，Version5的测试环境是被激活的(工件的自动再次载入，热代码交换等等)。
When installed on the same machine, the behavior of the Version 5 test environment is enabled (automatic reloading of artifacts, hot code swapping, and so forth).
您可能正在重复编写代码，或者被迫查找可能添加新页面元素的点，然后在这些点上处理“热元素”问题。
You'd be repeating code. And, you'd be forced to find all the possible spots that a new page element could be added to the page and deal with the "hot element" issue at that point.
例如，许多先进的编译器可以识别出构成“热”代码的循环代码块，即使它只包含对包含方法的一个调用。
For example, many JVMs are sophisticated enough to recognize that a block of code being looped over constitutes "hot" code, even if there's only a single call to the method that contains that block.
相反，热调用点(hot call site)更可能被内联，以使代码尽量短小，同时仍获得内联函数的优点。
Instead, hot call sites are more likely to be inlined to keep the code size small while still getting inline function benefits.
