profiler

Does anyone know of a way to find out how much memory an instance of an object is taking? For example, if I have an instance of the following object: TestClass tc = new TestClass(); Is there a way to find out how much memory the instance tc is taking? The reason for asking, is that although C# has built in memory management, I often run into issues with not clearing an instance of an object (e.g. a List that keeps track of something). There are couple of reasonably good memory profilers (e.g. ANTS Profiler) but in a multi-threaded environment is pretty hard to figure out what belongs where,

From android studio 3.0 Android Monitor turned to Android profiler . But, when using google glass device or other android kitkat devices it's showing below message in android profiler window: Device not supported. Android profiler requires a device with API 21(Lollipop) or higher. What's the solution for Kitkat devices to use the latest Android Profiler once android studio 3.0 available for update in stable version? It seems that the Android Device Monitor (Tools->Android->Android Device Monitor) is still available. I am having difficulty running its memory monitor, although it does seem to

Note: Although this question probably does not fit in with SO's usual programming questions, out of StackOverflow, ServerFault, SuperUser and Programmer's Exchange, only SO has any questions that make mention of this software, which is why I decided to post here. I used to use Anjlab's open source SQL Profiler tool, and found it to be invaluable. Unfortunately, it looks like the software has been converted to a paid version, with the all access to the open source version completely removed. Since this software is mentioned several times in questions here on SO, I was wondering if anyone still

Besides ruby-prof and and the core Benchmark class, what do you use to profile your Ruby code? In particular, how do you find the bottlenecks in your code? It almost feels like I need to work on my own little tool just to figure out where all the time is being spent in my code. I realize ruby-prof provides this, but the output is frankly very confusing and doesn't make it easy to find out which actual blocks of your own code are the source of the issue (it tells you about which method calls took the most time though). So I'm not really getting as much out of it as I'd like, and haven't really

I just started with Lua as part of a school assignment. I'd like to know if there's an easy way to implement profiling for Lua? I need something that displays allocated memory, variables in use regardless of their type, etc. I've been finding C++ solutions which I have been able to compile successfully but I don't know how to import them to the Lua environment. I also found Shinny but I couldn't find any documentation about how to make it work. There are several profilers available that you can check, but most of them target execution time (and are based on debug hook). To track variables, you

I want to find memory leaks in my java application but I don't know how to use Netbeans profiler to do that. There are several resources on the web that can give you a hand http://www.javapassion.com/handsonlabs/nbprofilermemory/ http://www.netbeans.org/kb/articles/nb-profiler-uncoveringleaks_pt1.html http://kirk.blog-city.com/more_on_memory_leaks.htm In a nutshell, you monitor the "surviving generators", objects that are kept in the memory by your application. When you see that this metric gets out of hand, you can switch to the Memory Live profiling mode, sort the classes by surviving

i would to know how to write a profiler? What books and / or articles recommended? Can anyone help me please? Someone has already done something like this? I would look at those open-source projects first: Eclipse TPTP ( http://www.eclipse.org/tptp/ ) VisualVM ( https://visualvm.dev.java.net/ ) Then I would look at JVMTI (not JVMPI) http://java.sun.com/developer/technicalArticles/Programming/jvmti/ Encouraging lot, aren't we :) Profilers aren't too hard if you're just trying to get a reasonable idea of where the program's spending most of its time. If you're bothered about high accuracy and

The problem is: VisualVM sampler shows call tree by time. For some method sampler shows only "Self time" so I can't see what makes this method slow. Here is an example . How can I increase the depth of profiling? Unfortunately sampling profilers are rather limited when it comes down to in-depth profiling due to a number of reasons: Samplers are limited by the sampling period: For example, VisualVM currently has a minimum sampling period of 20ms. Modern processors can execute several million instructions in that time - certainly more than enough to call several short methods and return from
