How To Reduce Cpu Usage In C# Application


I've seen other authors add settings to limit the number of threads the application will use, or limits of memory or swap space, but never CPU. It doesn't really limit how much processor time it'll get but it will tell the OS let other processes take priority. –M.Babcock Mar 20 '12 at 19:16 add a comment| 2 When should an author disclaim historical knowledge? If that does not work then the CPU is overloaded - get a faster CPU. are some comments I could make about the code itself but I would rather address the

This is my own personal work only. I am trying to get the CPU usage of more than one process at the same time. I would put usage of this inside some #ifdef so it's only used in Windows 2000/XP, because this method could change or be removed in future versions of Windows. Use all of it. –Brian Hooper Oct 7 '14 at 15:53 4 This question appears to be off-topic because it is about electronics and not about programming. –GlenH7 Oct 8

Or a two CPU machine so that you can allocate the work to one processor. I still didnot run the code but just want to make sure if we can monitor any process or not. Please note that disposal and ending the throttling needs to be implemented in the solution above, it is not production code.

Besides, modern CPUs (normally) have at least 2-4 cores.

Here's a simple Java implementation off the top of my head (just so you get the idea) that will throttle the CPU usage to 50% if you have a single threaded C# Limit Cpu Usage Of Thread In 24-bit True Color! | CSV And TAB File Parser | Easy Screen Capture Class | SideMenu | WIA WebCam Sample | WMI - Get Hardware Info | Automate Command Prompt The newer API function SwitchToThread[^] does but it does not include any timing mechanism.For a more robust and tunable solution you might consider using events (that you never actually set) and browse this site This class would contain a utility method that should be called on a regular basis (e.g.

So (Tn-To)/(Sn-So) <= R/100 => (Tn-To) X 100<=(Sn-So) X R => (Tn-To) X 100 - (Sn-So) X R <= 0 So if this equation is greater then zero, then we can Ben Post authorJuly 15, 2012 at 9:49 pm I think the most likely reason it shows 0% is because it really is very low. Every Mac that I've owned has at some point in its life run code at 100% CPU usage for days at a time. Willy.

C# Limit Cpu Usage Of Thread

The other methods are to help in the calculations. i noticed that when moving 750mb (multiple) files, it only used about 20% of the CPU usage... How To Reduce Cpu Usage In C# Application You cannot leave such an implementation to the O.S. C# Process Priority Here is a class that will limit CPU usage of a thread to a specified limit and also help to control its execution.

As most applications usually run in default priority, users using those computers will notice computer freezing and will be unable to do ought else on their computers. this content They only matter if two threads are asking for the CPU simultaneously, in which case the more important thread gets more time.What you have done in your code is throttling, which Reply With Quote January 3rd, 2007,03:26 PM #10 wfunction View Profile View Forum Posts Member Join Date Dec 2006 Posts 86 Re: how to reduce CPU Usage Wow - so, OK, Why are there no Imperial KX-series Security Droids in the original trilogy?

See How Can I Set Processor Affinity in .NET? but since {at least} Win2000 timer resolution 55 ms is gone forever .. This will tell your program to use only the processor(s) you want him to use. weblink m_lastTotalSystemTime.QuadPart = thissystime.QuadPart; m_lastThreadUsageTime.QuadPart = thisthreadtime.QuadPart; m_lastThreadName = Thread.CurrentThread.Name; return true; } } Sign In·ViewThread·Permalink Re: C# Version Lone Developer30-May-11 12:48 Lone Developer30-May-11 12:48 HiThank you posting the C# version.It

How can "USB stick" online identification possibly work? AndI needed to limit its execution so that its CPU usage would not go above a particular limit, irrespective of the hardware/processor over which the program was running. Only in such cases I would think about CPU utilization and potential sleeps yourself.

Adam taylor May 31, 2012 at 10:11 am hi every body.

The other answers appear highly theoretical and of no practical use in situations where the application is properly designed but still needs to be throttled. share|improve this answer edited Mar 20 '12 at 19:21 answered Mar 20 '12 at 19:15 Chris Shain 40.7k366106 2 It's worth noting this answer is incorrect given current versions of Given a process which you want to throttle, this is the logic: public static class ProcessManager { [Flags] public enum ThreadAccess : int { TERMINATE = (0x0001), SUSPEND_RESUME = (0x0002), GET_CONTEXT Generally the OS does a good job of scheduling application threads though, so setting the process priority is likely to have a better overall result.

But even better is Environment.TickCount since it is not dependent on the user not touching their clock. * SubtractTimes can be static. * I rolled the two properties into the code, TeXForm handling of derivative higher than two What is a non-vulgar synonym for this swear word meaning "an enormous amount"?

Why are Zygote and Whatsapp asking for root? There is nothing in the system that can set a CPU quota per process, all you can do is give up your CPU slice by inserting wait's in your program, but For an example of a service that still doesn't throttle itself and frequently annoys people, see Windows Installer Module. This code works for me but I just wonder I set Limit CPu usage to 45% but it uses 54-50 % ...

By the way I have a very similar app that makes cpu shoot 95% and i want it to run longer but must not spike CPU to 95% every time. –Simple For example, if your program is multithreaded and able to consume 100% of your two CPUs, then set his affinity to only use one CPU. The limit can be set by a user through a function of this class. */ class CPULimiter { //This integer stores last total system time. //total system time is sum of asked 4 years ago viewed 2172 times active 5 months ago Linked 19 How Can I Set Processor Affinity in .NET?

You can also set the CPU affinity if it is on a multi-processor box, limiting the processing to certain cores and leaving others free for other applications. If display hardware can display 120fps, there may be cases where animation could be shown at 120fps without adding motion blur, but could not be shown cleanly at lower frame rates hope someone here can give me this...
