profiler

I'm trying to find open source profilers rather than using one of the commercial profilers which I have to pay $$$ for. When I performed a search on SourceForge, I have come across these four C++ profilers that I thought were quite promising: Shiny: C++ Profiler Low Fat Profiler Luke Stackwalker FreeProfiler I'm not sure which one of the profilers would be the best one to use in terms of learning about the performance of my program. It would be great to hear some suggestions. You could try Windows Performance Toolkit . Completely free to use. This blog entry has an example of how to do sample

I use cProfile now but I find it tedious to write pstats code just to query the statistics data. I'm looking for a visual tool that shows me what my Python code is doing in terms of CPU time and memory allocation. Some examples from the Java world are visualvm and JProfiler . Does something like this exist? Is there an IDE that does this? Would dtrace help? I know about KCachegrind for Linux, but I would prefer something that I can run on Windows/Mac without installing KDE. A friend and I have written a Python profile viewer called SnakeViz that runs in a web browser. If you are already

How do I limit a SQL Server Profiler trace to a specific database? I can't see how to filter the trace to not see events for all databases on the instance I connect to. Under Trace properties > Events Selection tab > select show all columns. Now under column filters, you should see the database name. Enter the database name for the Like section and you should see traces only for that database. Todd Price In SQL 2005, you first need to show the Database Name column in your trace. The easiest thing to do is to pick the Tuning template, which has that column added already. Assuming you have the

I have been getting used to OpenCover over the past few days, and have I noticed that tests using Moles do not generate any Coverage information. I have created a small solution to isolate the problem, and have found that code coverage is generated only for tests that do not have the [HostType("Moles")] attribute. Reading around I have found this and this which seem to be NCover equivalents of my problem. They say that it is something to do with Moles running a profiler as well as the coverage tool, and that there is an environment variable CLRMONITOR_EXTERNAL_PROFILERS that can be set to

I've run into a few OutOfMemoryExceptions with my C#/WPF application and I'm running into some confusing data while attempting to profile the memory usage. When the app is typically running, Windows Task Manager shows the memory usage as somewhere around 34 MB (bounces around slightly as objects are created and garbage collected). When I run memory profiling applications such as CLR Profiler and dotTrace Memory , they show the total memory usage at around 1.2 MB. Why this huge discrepancy? What does Task Manager see that these profilers do not? UPDATE: I added some diag code to my application

So, I've recently started using Matlab's built-in profiler on a regular basis, and I've noticed that while its usually great at showing which lines are taking up the most time, sometimes it'll tell me a large chunk of time is being used on the end statement of a for loop. Now, seeing as such a line is just used for denoting the end of the loop, I can't imagine how it could use anything other than a trivial amount of processing. I've seen a specific version of this question asked on matlab central , but a consensus didn't seem to be reached. EDIT: Here's a minimal example of this problem: for i

Can anybody recommend a good code profiler for C++? I came across Shiny - any good? http://sourceforge.net/projects/shinyprofiler/ Callgrind for Unix/Linux DevPartner for Windows Not C++ specific, but AMD's CodeAnalyst software is free and is feature-packed. http://developer.amd.com/cpu/codeanalyst/codeanalystwindows/Pages/default.aspx Gprof if you use gcc. It may not be user friendly but still useful. Probably you will be interested in Intel VTune . Rather useful and allows to collect low-level events like cache misses which helps a lot in tuning.
