How to programmatically limit bandwidth usage of my c# application?
What you are looking for is called Bandwidth throttling And here is a good example how is this done, also review the comments to know how it is done from a client side. You may also want to take a look at this example too, putting things in a real application
How to detect Network Signal Strength in iOS Reachability
My original thought was to time the download of a file, and see how long it takes: @interface ViewController () <NSURLSessionDelegate, NSURLSessionDataDelegate> @property (nonatomic) CFAbsoluteTime startTime; @property (nonatomic) CFAbsoluteTime stopTime; @property (nonatomic) long long bytesReceived; @property (nonatomic, copy) void (^speedTestCompletionHandler)(CGFloat megabytesPerSecond, NSError *error); @end @implementation ViewController – (void)viewDidLoad { [super viewDidLoad]; [self testDownloadSpeedWithTimout:5.0 completionHandler:^(CGFloat megabytesPerSecond, … Read more
Bandwidth throttling in C#
Based on @0xDEADBEEF’s solution I created the following (testable) solution based on Rx schedulers: public class ThrottledStream : Stream { private readonly Stream parent; private readonly int maxBytesPerSecond; private readonly IScheduler scheduler; private readonly IStopwatch stopwatch; private long processed; public ThrottledStream(Stream parent, int maxBytesPerSecond, IScheduler scheduler) { this.maxBytesPerSecond = maxBytesPerSecond; this.parent = parent; this.scheduler = … Read more
How to get CPU usage and RAM usage without exec?
Use PHPSysInfo library phpSysInfo is a open source PHP script that displays information about the host being accessed. It will displays things like: Uptime CPU Memory SCSI, IDE, PCI Ethernet Floppy Video Information It directly parsed parses /proc and does not use exec. Another way is to use Linfo. It is a very fast cross-platform … Read more
Measuring memory bandwidth from the dot product of two arrays
There’s a few things going on here, that come down to: You have to work fairly hard to get every last bit of performance out of the memory subsystem; and Different benchmarks measure different things. The first helps explain why you need multiple threads to saturate the available memory bandwidth. There is a lot of … Read more
How do I simulate a low bandwidth, high latency environment? [closed]
For macOS, there is the Network Link Conditioner that simulates configurable bandwidth, latency, and packet loss. It is contained in the Additional Tools for Xcode package.
Detecting network connection speed and bandwidth usage in C#
Try using the System.Net.NetworkInformation classes. In particular, System.Net.NetworkInformation.IPv4InterfaceStatistics ought to have some information along the lines of what you’re looking for. Specifically, you can check the bytesReceived property, wait a given interval, and then check the bytesReceived property again to get an idea of how many bytes/second your connection is processing. To get a good … Read more
