latency

问题 I'm executing performance testing using JMeter and Blazemeter report, but the response time value is the same as latency time value. can somebody explain? I attach the graph results: Latency Time Graph Response Time Graph 回答1: It just means that the response is small/empty. The values are TTLB and TTFB, See explanantion about the difference Latency is a difference between time when request was sent and time when response has started to be received . Response time (= Sample time = Load time =

问题 I looking for the info that can help in estimating interrupt latencies on x86 CPUs. The very usefull paper was found at "datasheets.chipdb.org/Intel/x86/386/technote/2153.pdf". But this paper opened a very important question for me: how can be defined the delay provided by waiting of completion of the current instruction? I mean delay between recognition of the INTR signal and executing of INTR micro-code. As I remember, the Intel Software developer manual also tells something about waiting

问题 Based on this question made ​​by me: How to record and playback with NAudio using AsioOut With this code: [DllImport("Kernel32.dll", EntryPoint = "RtlMoveMemory", SetLastError = false)] private static unsafe extern void MoveMemory(IntPtr dest, IntPtr src, int size); private void OnAudioAvailable(object sender, AsioAudioAvailableEventArgs e) { for (int i = 0; i < e.InputBuffers.Length; i++) { MoveMemory(e.OutputBuffers[i], e.InputBuffers[i], e.SamplesPerBuffer * e.InputBuffers.Length); } e

问题 I have a simple spring boot application deployed on Kubernetes on GCP. The service is exposed to an external IP address. I am load testing this application using JMeter. It is just a http GET request which returns True or False . I want to get the latency metrics with time to feed it to HorizontalPodAutoscaler to implement custom auto-scaler. How do I implement this? 回答1: Since you mentioned Custom Auto Scaler. I would suggest this simple solution which makes use of some of tools which you

问题 I have array with more elements than posted here. I show only 2 in post but there are 10 showGreen variables, 10 additional threads, 10 "TextViews" and 10 isGreenBackgroundShouldAppear functions. As you see, when answer is correct, TextView1 or TextView2 becomes green on ACTION_DOWN and sets random image in image_view thus preparing next question. The problem is that if I use 10 threads which separately set value of answer for every TextView every 500ms, if user press correct answer TextView

问题 Is it true aligning data members of a struct/class no longer yields the benefits it used to, especially on nehalem because of hardware improvements? If so, is it still the case that alignment will always make better performance, just very small noticeable improvements compared with on past CPUs? Does alignment of member variables extend to member functions? I believe I once read (it could be on the wikibooks "C++ performance") that there are rules for "packing" member functions into various

问题 My latest project is using a javascript framework (jQuery), along with some plugins (validation, jquery-ui, datepicker, facebox, ...) to help make a modern web application. I am now finding pages loading slower than I am used to. After some js profiling (thanks VS2010!), it seems a lot of the time is taken processing inside the framework. Now I understand the more complex the ui tools, the more processing needs to be done. The project is not yet at a large stage and I think would be average

问题 I'm doing some research on In-Memory databases and am wondering what type of applications would benefit the most from the predictable latency characteristic of In-Memory databases. I can imagine online gaming, such as first person shooter games. I'm just wondering what other type of applications. 回答1: Not much surprisingly the very applications, that benefit from predictable latency (be it low, or not -- latency jitter bothers...) low-latency edge : HPC , where nanoseconds and sub-nanosecond
