...e. Or let's say: There are native compilers (creating machine code for the CPU to eat), and not-so-native-compilers (creating tokenized stuff, i.e. intermediate code, that some just-in-time compiler compiles to machine code before (or during) runtime ONCE), and there are "real" non-compilers that ne...

...ou will not always get the same timing for a function. This is because the CPU of your machine can be less or more used by other processes running on your computer, just as your mind can be more or less concentrated when you solve a math exercise. In the human mind, we can remember the solution of a...

...ocess(if run locally it will list the java process).Go to sampler, monitor CPU, take a snapshot after metod finishes. and you can get time taken by each method in call tree. its buddled in jvm/jdk. – arvin_v_s Jun 21 '17 at 4:13 ...

... @Rich.Carpenter: function pointers are nice for runtime CPU detection. Have multiple versions of some functions to take advantage of SSE, popcnt, AVX, etc. At startup, set your function pointers to the best version of each function for the current CPU. In your other code, just ...

... This depends on the CPU you're using, on the OS, on what other processes are doing, on what Java release you're using, and other factors. I've seen a Windows server have > 6500 Threads before bringing the machine down. Most of the threads w...

...报错，且不能通过编译。这样就避免了前面讲的类型安全问题与装箱拆箱的性能问题了。 总结： 数组的容量是固定的，您只能一次获取或设置一个元素的值，而ArrayList或List<T>的容量可根据需要自动扩充、修改、删除或插入数...

...坏在半路上了。于是两位工程师和一位经理就如何修车的问题展开了讨论。硬件工程师说：“我可以用随身携带的瑞士军刀把车坏的部分拆下来，找出原因，排除故障。”项目经理说：“根据经营管理学，应该召开会议，根据问...
