throttling

(This is in principal a language-agnostic question, though in my case I am using ASP.NET 3.5) I am using the standard ASP.NET login control and would like to implement the following failed login attempt throttling logic. Handle the OnLoginError event and maintain, in Session , a count of failed login attempts When this count gets to [some configurable value] block further login attempts from the originating IP address or for that user / those users for 1 hour Does this sound like a sensible approach? Am I missing an obvious means by which such checks could be bypassed? Note: ASP.NET Session is

I have a list of awaitables that I want to pass to the asyncio.AbstractEventLoop but I need to throttle the requests to a third party API. I would like to avoid something that waits to pass the future to the loop because in the meantime I block my loop waiting. What options do I have? Semaphores and ThreadPools will limit how many are running concurrently, but that's not my problem. I need to throttle my requests to 100/sec, but it doesn't matter how long it takes to complete the request. This is a very concise (non)working example using the standard library, that demonstrates the problem.

I have a WCF Service and an application with a Service Reference to it, and with the application I have a loop and in each iteration it's making a call to a method in this wcf web-service. The problem is that after about 9 calls or so, it just stops...and if you hit Pause button of VS, you will see that it's stuck on the line where it makes the call. After some time waiting for it, this TimeoutException is thrown: The request channel timed out while waiting for a reply after 00:00:59.9970000. Increase the timeout value passed to the call to Request or increase the SendTimeout value on the

I'm use mikeal/request to make API calls. One of the API's I use most frequently (the Shopify API). Recently put out a new call limit , I'm seeing errors like: Exceeded 6.0 calls per second for api client. Slow your requests or contact support for higher limits. I've already gotten an upgrade, but regardless of how much bandwidth I get I have to account for this. A large majority of the requests to the Shopify API are within async.map() functions, which loop asynchronous requests, and gather the bodies. I'm looking for any help, perhaps a library that already exists, that would wrap around the

I'm writing an application that will have multiple threads running, and want to throttle the CPU/memory usage of those threads. There is a similar question for C++ , but I want to try and avoid using C++ and JNI if possible. I realize this might not be possible using a higher level language, but I'm curious to see if anyone has any ideas. EDIT: Added a bounty; I'd like some really good, well thought out ideas on this. EDIT 2: The situation I need this for is executing other people's code on my server. Basically it is completely arbitrary code, with the only guarantee being that there will be a

I've written some applications than heavily use network, and I would like to test it over a slow network. I'm looking for a tool to simulate these kind of connections. I'm only interested in Windows tools. I've used Traffic Shaper XP on my XP dev box at work. It seems to handle any connection (not just HTTP). It wasn't perfect, but worked well enough for the tests I was doing. If you're on Windows maybe it'll do enough for you. Try dummynet . You will find lots of resources on the web, including this tutorial . Throughput, latency, jitter, and packet loss can all impact user experience.

The following Typescript performs each call to doSomething(action) one at a time. (Meaning the second item in the list does not get a call made until the first one is done). async performActionsOneAtATime() { for (let action of listOfActions) { const actionResult = await doSomethingOnServer(action); console.log(`Action Done: ${actionResult}`); } } This one will send all the requests to the server right away (without waiting for any responses): async performActionsInParallel() { for (let action of listOfActions) { const actionResultPromise = doSomething(action); actionResultPromise.then(
