profiler

问题 I'm trying to profile an app in c#, never done any kind of profiling before. I haven't been able to find much documentation on the profiler so far maybe someone here might know better. I have an app that when I click a toolbar button, kicks off a background thread to fetch me some data. The data is then prepared and displayed on the Main thread. I'm trying to profile this process to determine whether the time taken is in the preparation of the data or in the fetching, but I'm not having much

问题 I'm trying to use the NetBeans 7.1 profiler to profile a program which runs a series of hadoop tasks (local, single-process), but each task is started in a separate thread. I've set my root methods to be the map and reduce methods of the Mapper and Reducer which I'm using, but it seems like after thread 50, the netbeans profiler simply stops profiling. It doesn't recognize when the root methods are called again. The live results stop and snapshot I get at the end only seems to contain data

问题 I have a problem with the Symfony2 toolbar which is hidden when I add requires_channel: https in order to force HTTPS in some protected area of the website. If I remove requires_channel: https , the Symfony2 toolbar is displayed and I can click on it to see some details about the request (the normal behaviour). If I add requires_channel: https , no toolbar is displayed although the code is present at the end of the pages: <div id="sfwdt4b56c8" class="sf-toolbar" style="display: none"></div>

问题 I'm trying to improve the performance of some code in my site and found this profiler: https://github.com/loic-sharma/profiler I've followed the guidance on the site and included the following in one of the sites controllers: public function getTest() { $logger = new Profiler\Logger\Logger; $profiler = new Profiler\Profiler($logger); $profiler->startTimer('testLogging'); $data = Article::select(array( 'articles.id', 'articles.article_date', 'articles.image_link', 'articles.headline',

问题 I have a native C++ project that uses COM to communicate with a separate project in VB.NET. I have been able to successfully profile the native project in the past by attaching the project to a separate exe that references the native dll. I'm now trying to profile the native project by connecting to dllhost.exe. This configuration works, since I'm able to debug through dllhost, but if I try and profile the code (or just attach the profiler to dllhost while I'm debugging), the profiler stops

问题 I did a lot of searching but still could not figure out why SQL Server Profiler shown the very unusual numbers. Scenario: Our web application thrown a SqlException complaining timeout expired (once in a while), so i decided to use the SQL Profiler to trace the long running query. But the result turned out pretty strange, the Duration was a very huge number and StartTime was greater than EndTime. I really appreciate for any advice of where i should further look into. (Please take a look at the

问题 In TensorFlow Eager, I can use Python's profiler to profile code that operates purely in eager mode. However, if I "compile" a python function to a graph function using tf.function or tf.contrib.eager.defun , that function becomes opaque to python - the profiler cannot enter it. I have found out how to profile a TF graph in graph mode, but I don't know how to do it with a graph function in eager mode. Specifically, if I construct a function like this, tf.enable_v2_behavior() @tf.function def

问题 I'm trying to profile my software in order to optimize it. I used gprof with the compilation flag -g -pg -O3 but the result are not giving me enough precision. Here is my Stacktrace of compilation: $: make clean; make; rm -f ./obj/*.o rm -f ./bin/mdk-verifier rm -f ./grammar/modal.output rm -f ./grammar/modal.tab.h rm -f ./grammar/*.cpp rm -f ./lex.backup bison -d -t -l -v -o ./grammar/modal.tab.c ./grammar/modal.y && mv ./grammar/modal.tab.c ./grammar/modal.tab.cpp g++ -O3 -g -pg -fPIC -std

My application runs a combination of C++ (COM objects) and C# managed code. Sadly there is a n elusive memory leak I need to trace down. I've tried AQTime, which looked good on paper, but my app keeps crashing when running underneath it. Any suggestion for a better alternative? 回答1: Massif is a heap analyzer,
