Is it possible to set custom CPU throttling in Chrome DevTools?
Custom values for Emulation.setCPUThrottlingRate can be set right in Chrome, but you need to open a Dev Tools window on the Dev Tools window to change the setting programatically. Open Dev Tools; make sure it is detached (open in its own window). Open Dev Tools again on the Dev Tools window from step 1 using … Read more
What is the best way to implement a rate-limiting algorithm for web requests?
We found out Token Bucket is better algorithm for this kind of rate-limiting. It’s widely used in routers/switches so our operation folks are more familiar with the concept.
WCF stops responding after about 10 or so calls (throttling)
The default number of allowed concurrent connections is 10. Most likely your client is not closing the connections. To increase the number of concurrent calls, you will have to add your behavior to the service configuration, not the client.
‘ab’ program freezes after lots of requests, why?
It sounds like you are running out of ephemeral ports. To check, use the netstat command and look for several thousand ports in the TIME_WAIT state. On Mac OS X the default ephemeral port range is 49152 to 65535, for a total of 16384 ports. You can check this with the sysctl command: $ sysctl … Read more
Throttle and queue up API requests due to per second cap
For an alternative solution, I used the node-rate-limiter to wrap the request function like this: var request = require(‘request’); var RateLimiter = require(‘limiter’).RateLimiter; var limiter = new RateLimiter(1, 100); // at most 1 request every 100 ms var throttledRequest = function() { var requestArgs = arguments; limiter.removeTokens(1, function() { request.apply(this, requestArgs); }); };
Throttling CPU/Memory usage of a Thread in Java?
If I understand your problem, one way would be to adaptively sleep the threads, similarly as video playback is done in Java. If you know you want 50% core utilization, the your algorithm should sleep approximately 0.5 seconds – potentially distributed within a second (e.g. 0.25 sec computation, 0.25 sec sleep, e.t.c.). Here is an … Read more
How can I debounce a method call?
Here’s an option for those not wanting to create classes/extensions: Somewhere in your code: var debounce_timer:Timer? And in places you want to do the debounce: debounce_timer?.invalidate() debounce_timer = Timer.scheduledTimer(withTimeInterval: 1.0, repeats: false) { _ in print (“Debounce this…”) }
CPU throttling in C++
I am not aware of any API to do get the OS’s scheduler to do what you want (even if your thread is idle-priority, if there are no higher-priority ready threads, yours will run). However, I think you can improvise a fairly elegant throttling function based on what you are already doing. Essentially (I don’t … Read more
How do I throttle my site’s API users?
Ok, there’s no way to do what I asked without any writes to the server, but I can at least eliminate logging every single request. One way is by using the “leaky bucket” throttling method, where it only keeps track of the last request ($last_api_request) and a ratio of the number of requests/limit for the … Read more
