measure CPU usage per second of a dynamically linked library

放肆的年华 提交于 2019-12-25 01:43:49
问题 I have a sample application which uses a dynamically linked library library.so . I was measuring CPU usage of the sample application with the top command. But it shows CPU usage of both sample app and library.so per second. But I want to see the CPU usage of only the library.so . Is there anyway to do this? I heard its achievable with htop but could not find out how. I used the tree view but it shows several processes as the sample app process. I could not understand which one is library.so .

Running several AWK scripts at the same time with 100% CPU load

混江龙づ霸主 提交于 2019-12-24 20:58:14
问题 So I want to run 4 AWK scripts at the same time so that they run in parallel on all my CPU cores. This should lower my runtime to 25% of the total runtime, which means it only has to run for approximately 24 hours (instead of 4 days). Now all works fine, but when I do this I would obviously get a 100% CPU load for 24 hours. I have never done this before and I'm planning on starting the scripts tonight so I can keep them running overnight and tomorrow during the day. Now I'm a bit afraid that

Simple DB query on Google App Engine taking a lot of CPU time

耗尽温柔 提交于 2019-12-24 20:21:37
问题 I'm fairly new to Google App Engine and Python, but I did just release my first real-world site with it. But now I'm getting problems with one path that is using significantly more CPU (and API CPU) time than the other paths. I've narrowed it down to a single datastore fetch that's causing the problem: Carvings.all().fetch(1000) Under the App Engine dashboard it's reporting "1040cpu_ms 846api_cpu_ms" pretty reliably for each request to that path. It has seemed like this may be the source to

High CPU usage from jquery?

问题 There is a specific set of actions that cause the website that I am building on my localhost to freeze and cause the CPU usage to jump up to 25% or so. I am building a sort of tree structure , where the child row is loaded depending on the currently selected parent node. So, it is necessary for me to be able to save and load the objects which contain the information for all of the children, depending on the selected parent. The issue occurs when I am trying to update the information of a

Gauge/measure CPU usage without TaskMgr?

倖福魔咒の 提交于 2019-12-24 10:57:56
问题 I'm trying to gauge the CPU utilization level during a long-running process. I suspect that everytime I run task-manager to view the data, the process' CPU utilization goes down because taskmanager has a higher priority. If I give my process RealTime priority, then task manager completely locks up and I cannot use it. I want most of my CPU cycles dedicated to this process, and I want to get a rough idea of how much it is utilizing. I don't need a second-by-second monitor, but just a few

CPU usage shooting up when I am running a for-in loop: OS-x app

坚强是说给别人听的谎言 提交于 2019-12-24 08:12:56
问题 When my loop runs for about 15k times too much CPU is being used. It's in the range of 90 -100 % always. What I am doing inside the loop is a series of Core data entity updating/creation. Why does that happen? I am running my process in background and I have specified the thread priority to minimum value too! 回答1: Paul R is correct - the system will achieve the tasks in the loop as quickly as possible given the resources it has. In this case, it is manipulating Core Data objects in the

Artificial generation of cpu load in Java

六月ゝ 毕业季﹏ 提交于 2019-12-24 04:48:04
问题 Is there a simple way to generate a constant CPU load in Java? Like generate CPU load at 60%. 回答1: Have not tested this, but it might roughly work, to make your application work and sleep in the correct ratio. Something like (pseudocode): load = 60; do forever time = current_system_time_ms() + load while (current_system_time_ms() < time) // just consume some time for 60 ms end SLEEP(100 - load); // sleep for 40 ms end Ok, you asked for a simple way, but ... :) 回答2: I think that's not even

TCP Server high CPU usage

徘徊边缘 提交于 2019-12-24 03:26:31
问题 C# Visual Studio 2013 I'm working on a rough TCP Server/Client. It works like this: Client sends message to server > Server sends "response" to client. I have this in a loop as I'm going to use this transfer of data for multiplayer in a game. However, I ran a performance test because my TCP Server was using a lot of my CPU when more than three clients connected. The performance profiler said the following method was responsible for 96% utilization. Can you help me fix this? private static

Finding the average CPU usage for Windows machine in Java [duplicate]

南楼画角 提交于 2019-12-23 13:01:06
问题 This question already has answers here : How do I monitor the computer's CPU, memory, and disk usage in Java? (11 answers) Closed 6 years ago . I have searched all over the internet for about two days now. I have found a lot about how to find the CPU usage using VB and anything in the .NET framework. I am not using the .NET framework so these are irrelevant, I feel. What I really need is results similar to the ones shown in the "CPU Usage" section in a Windows Task Manager under the
