throttling

问题 Lets assume that I'm dealing with a service that involves sending large amounts of data. If I implement this with WCF, will WCF throttle the service based on how much memory each request takes to serve? Or will I be getting continuous out of memory exceptions each time I receive a large number of hits to my service? I'm quite curious as to dealing with this problem outside of WCF, I'm still a bit new to service development... 回答1: While using the binding attributes and readerQuotas like

问题 I've got a backup application here which connects to various webservices and downloads/uploads files from ftp or http servers. What is the easiest way to limit the bandwidth usage of my application? I need to do that because the application once installed and running will be slowing down internet access for all office people, which eventually will get me into hell. So I'd like to implement a speed-limit which is active during the work-hours and gets disabled at night. 回答1: What you are

问题 I need a component/class that throttles execution of some method to maximum M calls in N seconds (or ms or nanos, does not matter). In other words I need to make sure that my method is executed no more than M times in a sliding window of N seconds. If you don't know existing class feel free to post your solutions/ideas how you would implement this. 回答1: I'd use a ring buffer of timestamps with a fixed size of M. Each time the method is called, you check the oldest entry, and if it's less than

问题 I would like to simulate packet delay and loss for UDP and TCP on Linux to measure the performance of an application. Is there a simple way to do this? 回答1: netem leverages functionality already built into Linux and userspace utilities to simulate networks. This is actually what Mark's answer refers to, by a different name. The examples on their homepage already show how you can achieve what you've asked for: Examples Emulating wide area network delays This is the simplest example, it just

问题 This is my login controller function use ThrottlesLogins; protected $maxLoginAttempts = 3; protected $lockoutTime = 300; public function login(Request $request) { if ($this->hasTooManyLoginAttempts($request)) { $this->fireLockoutEvent($request); return $this->sendLockoutResponse($request); } $validator = Validator::make(Input::all() , ['credential' => 'required|min:2|max:255', 'password' => 'required|string|min:8', ]); $cred = $request->credential; $pw = $request->password; $remember = (Input

问题 I'm running CF Server 4.510 on Microsoft Windows Server 2003 R2 Standard SP 2. One of our list serve applications on this server sends out a large amount of emails, prompting an excessive out-queue length alert from Barracuda. What I'm looking to do is throttle these emails so as to not send out this alert and bog down the server. 回答1: Log the email required to be sent in DB. Use cfschedule, fetch X number of email's at a time and send them. 来源： https://stackoverflow.com/questions/16349751

问题 How can I ensure that the ThrottleEvent is supported by the current used browser? I can see that they mention some browsers which support it: The platforms that support throttling and pausing are currently the following: Flash Player Desktop Mac and Windows, AIR Mobile, and Flash Player Android. The following platforms do not dispatch the ThrottleEvent automatically because they do not yet support pausing or throttling: AIR for TV devices, AIR for desktop, and Flash Player Linux Desktop. But

问题 I would like to throttle the following ajax live search function I wrote. I made it so that requests are only sent if a minimum of 2 characters are entered. I also want to throttle the ajax for a quarter of a second to give the user a chance to type what they want. I wrapped the ajax in a setTimeout function, but that didn't work. $('#search').keyup(function() { var string = $(this).val(); if (string.length >= 2) { $.ajax({ 'type': 'GET', dataType: 'html', 'url': url, 'success': function(data

问题 I need to transmit the touch position in Chrome for Android continuously to a Node.js server using Socket.io . However, I guess, the transmission is too fast. The first few values receive the server (For the first touch about six values, later only two or three values), then there seems to be a traffic jam. For many seconds the server receives nothing. Then, suddenly all missed values suddenly arrive at the server. But not continuously... I think I must reduce the traffic from client to

问题 I have an observable that I am subscribing on. This obsevable will be returning an object that has a property called ActivationType that can be set multiple times. What I am trying to achieve is log a message whenever ActivationType is set to "Type1". However, if ActivationType is set to "Type2", log the message only once and wait for 30 seconds before logging again if ActivationType is "Type2". So if I have: myObservable .Where(o => o.ActivationType == "Type1" || o.ActivationType == "Type2")
