profiler

问题 My user has countTasks property, with corresponding setter and getter: class User implements UserInterface, \Serializable { /** * @var integer */ private $countTasks; } I want this property to be always shown in the application's navigation bar (the "14" number in red): Obviously, this property should be set for every controller. (Actually, only for every that deals with rendering the navigation bar, but that's not the case here). So the application should count tasks for the currently logged

问题 I'm trying to create an animated plot but my code is very slow, perhaps the method I'm using is too naive. In the below example, I have 4 subplots each with 3 lines, which I update in a 'time' loop. clc;clear;close all; state = {'$x-Position$','$x-Velocity$','$y-Position$','$y-Velocity$'}; ylabels = {'$x$','$\dot{x}$','$y$','$\dot{y}$'}; options1 = {'interpreter','latex'}; options2 = {'interpreter','latex','fontsize',20}; maxT = 300; for pp = 1:4 hh1(pp)=subplot(2,2,pp); xlabel('$t$',options2

问题 I want to analyze memory consumption in my device but I didn't find Android profiler tab in Android Studio as seen below : Please who could help me to show up this tab. 回答1: If you take a look at top menu you will see a profile icon click it and it will start your app with profile attached. See the below screenshot to get the idea. 回答2: The perfect tip for Android Studio: When you need to find something, write it in the help tab, like this: If you know what you're looking for, you will find

问题 I have an application. I compile it using vs2008 team system. To run this app some certain environmental variables need to be set, such as SYSTEM_MODULE_PATH. My app loads system modules from there. Without this variable it wont run. So When I profile it, I want to set this variable so that my application runs properly. Now my question is, Where do I set this variable? 回答1: Start -> Control Panel -> System -> advanced Tab -> Environment variables or CMD -> SET [variable=[string]] 回答2: I fixed

问题 Getting this exception in Symfony 2.5.5 with Swiftmailer 5.3.0. I'm following the cookbook example exactly. The error is thrown when calling MessageDataCollector#getMessages() : // Check that an e-mail was sent $this->assertEquals(1, $mailCollector->getMessageCount()); $collectedMessages = $mailCollector->getMessages(); $message = $collectedMessages[0]; The message count assertion is also failing with a value of zero. As far as I can tell the collector is failing to do any actual collecting

问题 Merged with What Are Some Good .NET Profilers?. Recently I used RedGate ANTS profiler which seems pretty good, but the application I tried to profile was crashing due to DivideByException, where as running in inside Visual Studio was fine for both debug and release. Are there other/better C# profilers that you know of? 来源： https://stackoverflow.com/questions/612711/best-c-sharp-profiler

问题 I'm attempting to use VsPerfCmd.exe to profile branch misprediction and last level cache misses in an instrumented native application. The setup works as it says on the tin, but the results I'm getting don't seem sensible. For instance, a function that always touches a data set of 24MB is reported to only cause ~700 cache misses when being called ~2000 times. Now let me put this into perspective - The function linearly traverses two arrays of 1024*1024 elements of 12-byte elements. For every

问题 I need to know what file a specific program read. (this specific program is based on .net). Is there a recommendation for a good profiler? 回答1: Take a look at Process Monitor, it can tell you exactly when and what files are opened and closed by any Windows process, read/write operations, etc. 回答2: Can you run the program under an IDE such as Visual Studio? Are you asking what is the name of the file that the program spends most of its time reading? If so, then the simplest way to find out is,

问题 Using the jmap -histo command on a running process, every 30 minutes or so, I found one kind of object that is obviously a memory leak (in a desktop app). The object responsible for the leak ( I.e. the only kind of object whose number of instances grows over time, and by a huge amount) is int[] . I suspect BufferedImage to be the culprit but I'm not sure about that (I took great care about flushing/nullifying BufferedImage s but I still think that's where the leak hangs). However I'm also
