Is there free and good line-level profiler for PHP? I'm using xdebug and it's relatively good but it gives me function level output and sometimes it's hard to see where exactly all the time spent in the function goes. ...
I am using JetBrains dotTrace, I've profiled my app which is entirely CPU bound. But the results as you walk down the tree don't sum to the level above in the tree, I only see method calls not the body lines of the node in questions method. Is it possible to profile the source code line by line. i.e for one node: SimulatePair() 99.04...
I'm trying to optimize a set of stored procedures. These stored procedures are on Server A and do the following actions: Delete data on Server B based on a parameterized query on Server A DELETE FROM B (via linked server) DO SOME JOIN ON A WHERE A.x IN (@ID1, @ID2, @ID3, @ID4) Insert data on Server B based on a parameterized query on ...
Title pretty much says it all. I know about Redgate's Ants Profiler which I hear is awesome but it's also $400. Any cheaper alternatives out there that will at least point me to where I might need to optimize my code? ...
I need to profile some code running C++ on Linux. Can you guys recommend some profilers? ...
Does anyone have experience profiling a Python/SQLAlchemy app? And what are the best way to find bottlenecks and design flaws? We have a Python application where the database layer is handled by SQLAlchemy. The application uses a batch design, so a lot of database requests is done sequentially and in a limited timespan. It currently tak...
Long story short, I'm working on a .NET profiler that at one point gets a notification that a managed thread is running on a certain native kernel thread, which is not the currently executing thread. In this notification, I'm hoping to record a pointer in the TLS of the target thread. Again, that's not the current thread. I'm not seeing...
Hi, I am going to implement an internal profiler for memory on linux. I want to save the stack for each malloc/free/realloc. I am trying to use "pstack" to get the stack trace everytime. But the overhead is too high. Is there any lightweigt approach to get the call stack in C code? I know there are some tools like "valgrind, google pro...
Profiler/profiling related issue with Cucumber testing. One of our cucumber tests run fairly slow. In stead of guessing on where our application is spending time, I'd like to know programatically. How do I trigger a cucumber test with a profiler??? What did not work: $ URL=/projects/by/114951412 #URL to slow rails page $ script/...
This could be a borderline advertisement, not to mention subjective, but the question is an honest one. For the last two months, I've been developing a new open source profiler for .NET called SlimTune Profiler (http://code.google.com/p/slimtune/). It's a relatively new effort, but when I looked at the range of profilers available I was...
Once I've attached the Netbeans profiler to a remote JVM, I end up with errors in the server log post which the application server doesn't start up. There have been posts like this on the netbeans forum about this too, but the solution to this problem has not been posted yet. Did anyone out there face this issue and did you manage solv...
I am running cygwin on windows and using latest version of gprof for profiling my code. My problem is that the flat profile shows zero sec for each of the functions in my code, I even tried to loop the functions(tried a for loop for a million) but gprof is unable to accumulate any time .Please help . Here is one of my sample function. b...
I have a fairly large object-oriented php 5 project, and as part of a change impact analysis, I'd like to compile a report on the usage of each existing class throughout the project. It would help me immensely if I could find an existing tool that will analyze all the files in my project and generate some sort of report that lists, for...
Hi Friends, I want to profile my code on arm 9, Is there any profiler which can give me function call timings and total cycles taken by each function? I would prefer any free profiler. I loved to work with kcachegrind in linux. Thanks, Sunny. ...
Hi, I started to program in Scala recently. I'm looking for a free Scala profiler. Reading from the language's official site led me to YourKit, but the program was not a free one. Googling "scala profiler" didnt give me any relevant result. So how do I profile my program written in Scala? I prefer a graphical plugin to Netbeans or Ecli...
Hi, is there a way we can view the incoming query requests to mysql server. I have a scenario where my asp.net application refuses to execute a query, but the same query executes inside of a mysql query browser. I have installed the mysql dotnet connector (5.0.9) via which I can conncet to the database. I have referred this page, but I ...
I love the profiling tools that Red Gate makes for when I write in C#. Right now I am writing an application for iPhone in Objective-C and I am having a hard time adjusting to Instruments. It's just not as easy to use. Does anybody have a better code profiler for memory and performance? If not, any good tutorials for instruments? Th...
I run the Visual Studio 2008 profiler on a "RelDebug" build of my app. Optimizations are on, but inlining is only moderate, stack frames are present, and symbols are emitted. In other words, RelDebug is a somewhat optimized build that can be debugged (although the usual Release caveats about inspecting variables applies). I run both the...
I wrote a persistent network service in Perl that runs on Linux. Unfortunately, as it runs, its Resident Stack Size (RSS) just grows, and grows, and grows, slowly but surely. This is despite diligent efforts on my part to expunge all unneeded hash keys and delete all references to objects that would otherwise cause reference counts...
hi i need to capture the loading time of each http object such as img src="" and script src="" if it is impossible to loop the http elements, i can build an array and than loop that i know that i can use firebug, but i need that inside js thanks ...
