svchost using so much cpu

At present, there is a project on hand, which is to run a website on an embedded device with a linux system. The CPU of the device is in the RAM structure, with a single core and 1 GB. We set up Apache + Mysql + php in the system, and then write a website to run it. It seems like a vro. At present, there is a project on hand that runs a website on an embedded device with a linux system. The CPU of the devi

High-precision timing using CPU timestampsHttp://www.3800hk.com/Article/cxsj/vc/zhlbcvc/2005-08-06/Article_32674.html For performance-focused program developers, a good timing component is both a mentor and a mentor. Timers can be used as program components to help programmers precisely control program processes, and are also a powerful debugging weapon. experienced programmers can determine program perfo

Previously in Yuber GitHub issues saw the use of JS detection of CPU usage, feel very good. In particular, the implementation of a bit, plus a histogram of the function can be intuitive to see the situation of CPU utilization. See the effect: Transmission door Realize the idea In fact, is setinterval, using the current time minus the last execution timer recor

Using WPF to dynamically display CPU usageOpen Source Framework Admin 9 month ago (07-14) 1337 views WPF-based open-source chart controls have a lot, most of them are static charts, if you need to draw the CPU utilization of such dynamic data is inadequate, Microsoft Open source Dynamicdatadisplay control to compensate for this deficiency, in order to make a mem

This article mainly introduces python and bash methods for calculating CPU utilization. It involves Python's reading skills for system hardware information and has some reference value, for more information about how to calculate the CPU usage in python and bash, see the following example. Share it with you for your reference. The details are as follows: At the beginning, a bash implementation was written;

display of DataView is inaccurate.Workaround (Pending validation):1. Use the built-in Zabbix variable proc.cpu.util[2. Modify the commands in the script, using the following method instead:First, get the PID of the process name, and then combine top to run the following command:Top-b-n 1-p $pid 2>1 | Awk-v pid= $pid ' {if (= = pid) print $9} '3. Modify the commands in the script, using the following method
