I guessed that the just-in-time compilation probably had some startup overhead that swamped the running time .

我猜测大概是即时编译所需的启动开销拖累了运行时间。

Modern JVMs typically let code run for a while ( usually purely interpreted ) in order to gather profiling information before doing Just-in-time ( JIT ) compilation ( see Resources ) .

在执行即时（Just-in-time，JIT）编译之前，现代的JVM通常会运行代码一段时间（常常是纯解释式运行），从而收集剖析信息（参见参考资料）。

These statistics dispense data on the basic JVM features , such as Just-In-Time ( JIT ) compilation , class loading , memory allocation , and most interestingly , garbage collection .

这些统计信息涉及诸如即时（JIT）编译、类加载、内存分配以及最有趣的垃圾收集之类基本的JVM特性。
