throttling

问题 I am hitting into a problem with my company application. I am going to summarize the system key elements: My company's system is running since few years on Windows XP and 7 (Home, Pro, Basic) machines. It has been written in .NET 4.0 and based upon WCF. It uses the default throttling values (MaxConcurrentSessions = 100 * CPU (4) : enough for our workload). The main service is hosted by a stand alone deamon process (not IIS). The main service is configured as Multithraded/PerSession instances.

问题 Is there anyway to prioritize or throttle a query at all in MySQL? I'm a DBA on a server that sees a lot of unoptimized queries come into the server and they just destroy the CPU. I'm looking at throttling certain users that hit on the database in poor fashion. Clarification: I realize that MySQL has facilities built in to limit number of queries, connections, etc. But those aren't really the issue, it's that once in a blue moon a user will send an unoptimized query, and I'd need to time it

问题 I made an XNA image viewer, but it always redraws the scene, even if it's not changing, and it's making my netbook burn like hell, so I'd like it to pause drawing when nothing's changing. Reducing framerate to 1 is one way to keep it cool, but it results in laggy output. How do I prevent the redraw while there is no input? This problem was solved, but another problem was found — the game consumes a lot of CPU when its window is in focus, but when it's not, it only takes about 1% of the CPU.

问题 Update : I'm on Java 1.6.34 with no chance of upgrading to Java 7. I have a scenario where I am only allowed to call a method 80 times per minute. It's actually a service API written by a 3rd party, and it "shuts down" (ignores calls) its API if you call it too many times: public class WidgetService { // Can only call this method 80x/min, otherwise it // it just doesn't do anything public void doSomething(Fizz fizz); } I'd like to write an ApiThrottler class that has a boolean canRun() method

问题 I am a bit uncertain with the concepts of throttle and debounce functions. As I get it: we debounce a function that should be called after a certain event has happened. It is used in events like drag, keyup, etc. with the purpose of not firing all the time the event gets fired but instead when the series of events is done. Typically after a whole word has been typed, or a drag or resize sequence has ended. we throttle a function that should fire while a series of events is happening, but when

问题 I asked a question about how to throttle a python upload, which sent me to this answer, where I was informed of a little helper library called socket-throttle. That's all fine and dandy for regular HTTP and probably also for most plain uses of the socket. However, I'm trying to throttle an SSL connection, and trying to combine socket-throttle with the stock SSL library (used implicitly by requests ) causes an exception deep in the guts of the library: File "***.py", line 590, in request r =

问题 Looking at the below diagram, how to use netem / tc to drop 10% of packets and delay them by 2ms for a single IP? +----------------+ | | | Test Client |--------------+ | 148.341.10.15 | | +----------------+ | +----------------+ | | | |------------| Server | | | | +----------------+ | +----------------+ | | | | Normal Cleints |--------------+ | | +----------------+ From researching it should be possible however this looks to be more complex use case (as usually it is done on the interface and

问题 I would like to know if we should throttle async tasks if the number of tasks to complete is big. Say you have 1000 URLs, do you fire all the requests at once and wait for all: var tasks = urlList.Select(url => downloadAsync(url)); await Task.WhenAll(tasks); Or do you batch the requests and process one batch after another: foreach (var urlBatch in urlList.BatchEnumerable(BatchSize)){ var tasks = urlBatch.Select(url => downloadAsync(url)); await Task.WhenAll(tasks); } I thought that batching

问题 My application has background threads running, but because of optimization is done in Chrome by default, those threads are throttled when the browser is minimized or running in the inactive tab. We have flags to disable the throttling done by Chrome. I have disabled these 2 flags in Chrome --pause-background-tabs -> disabled --disable-background-timer-throttling -> disabled But still, I could see the throttling is still happening in inactive tabs/minimized browser of chrome, any idea how to

问题 How can I add a delay to an event (OnInput) in Blazor ? For example, if a user is typing in the text field and you want to wait until the user has finished typing. Blazor.Templates::3.0.0-preview8.19405.7 Code: @page "/" <input type="text" @bind="Data" @oninput="OnInputHandler"/> <p>@Data</p> @code { public string Data { get; set; } public void OnInputHandler(UIChangeEventArgs e) { Data = e.Value.ToString(); } } 回答1: Solution: There is no single solution to your question.
