profiler

I am writing an application using python3 and am trying out asyncio for the first time. One issue I have encountered is that some of my coroutines block the event loop for longer than I like. I am trying to find something along the lines of top for the event loop that will show how much wall/cpu time is being spent running each of my coroutines. If there isn't anything already existing does anyone know of a way to add hooks to the event loop so that I can take measurements? I have tried using cProfile which gives some helpful output, but I am more interested in time spent blocking the event

因为最近做项目迁移，迁移之后发现有些地方竟然变慢了！需要一个好的Profiler工具，定位最为耗时的地方。在翻淘宝中间件团队博客 http://rdc.taobao.com/team/jm/ 的时候发现了TProfiler，于是试用了一下。 总体来说使用还算简单，文档虽然说不上面面俱到，但是仍然是能让人上手了。 比较重要的是配置文件，有几个注意点： 配置文件需要所有属性完整，不然会报"IllegalArgumentException source can't be null"。 profile.properties 有一个样例，在man/resources目录下。 eachProfUseTime = 5 #表示每次profiler的时间，一次profiler结束后，写入到tprofiler.log文件中 eachProfIntervalTime = 50 #profiler的间隔 TProfiler是一个线上profile工具，之所以profiler间隔很大，是为了不影响线上业务。建议在测试环境，将eachProfIntervalTime设置成1或者0，eachProfUseTime尽量调大，这样比较好看结果。 还有一个client，可以做flushmethod等操作。如果不主动flush，会等到时间周期结束后才写tmethod.log文件。

I'd like to profile a method of a function in Python, using cProfile. I tried the following: import cProfile as profile # Inside the class method... profile.run("self.myMethod()", "output_file") But it does not work. How can I call a self.method with "run"? Use the profilehooks decorator http://pypi.python.org/pypi/profilehooks EDIT: Sorry, didn't realise that the profile call was in a class method. run just tries to exec the string you pass it. If self isn't bound to anything in the scope of the profiler you are using, you can't use it in run ! Use the runctx method to pass in the local and

I am running a PHP daemon to be profiled. The started php process loads all required data, forks itself to distribute workload over all cores, waits for the forked children to finish, and collects the results generated by the children. Since I am sharing CLI environment with other users, I need to start xdebug profiling by injecting php.ini values into the shell call. $ php -d xdebug.profiler_enable=1 -d xdebug.profiler_output_dir="/home/xxx" daemon.php The generated cachegrind-file, how ever, profiles the parent and hence shows 90% sleep. Is there a way to profile the workers without building

I added this to my Global.asax.cs: protected void Application_BeginRequest() { if (Request.IsLocal) { MiniProfiler.Start(); } } protected void Application_EndRequest() { MiniProfiler.Stop(); } I added @MiniProfiler.RenderIncludes() just below the </body> tag in _Layout.cshtml. In my controller I'm using: public class HomeController : Controller { public ActionResult Index() { var profiler = MiniProfiler.Current; // it's ok if this is null using (profiler.Step("Set page title")) { ViewBag.Title = "Home Page"; } using (profiler.Step("Doing complex stuff")) { using (profiler.Step("Step A")) { //
