问题 This feels like a silly question, but what do the various numbers mean on react-native performance monitor? I haven't been able to find in the docs. I understand RAM. What are the others? What do the two separate numbers mean for Views? Is that frames per second? What should I read to in order to become competent on how to use this tool? How reliable is this tool? What benchmarks should I be aiming for? 回答1: Thanks @diedu for posting a link (to a post, which has a comment w/ this youtube vid)

问题 Perfmon is a Windows utility that helps the developer to find bottlenecks in his applications, by measuring system counters. I was reading a perfmon tutorial and from this list of essential counters I have found the following ones on my machine: PhysicalDisk\Bytes/sec_Total Network Interface\Bytes Total/Sec\nic name But I haven't found the following counters nowhere: Processor\% Processor Time_Total Process\Working Set_Total Memory\Available MBytes Where do I find them? Note that my Windows

How to get CPU usage statistics on Android?

由 岁酱吖の 提交于 2019-11-26 19:30:03
问题 I want to get the overall CPU usage on Android, similar to what Windows' Task Manager does. I can parse the output of the top program included in Android, but if there is a API call that does the same thing, it would be better. Any pointers? 回答1: ATTENTION : This answer is old and does NOT work on newer versions of Android due to enhanced security mechanisms. For complete CPU usage (not for each process) you can use: /** * * @return integer Array with 4 elements: user, system, idle and other
