Hello everyone. I want to copy profiling data to a table I create in MySql. I want the table to contain the exact data that I get from the command SHOW PROFILES; For example, if I have this: mysql> show profiles; +----------+------------+--------------------------------+ | Query_ID | Duration | Query ...
jQuery 1.4 released recently and the new website shows some performance charts where 1.4 is clearly better, but has someone already done an analysis of overall performance improvement of 1.4 vs 1.3? If not, how do I profile both on my sites/pages, are there any tools? Can't wait to find out how fast is 1.4 compared to the previous versi...
I am trying to figure out where my C++ program is spending its time, using gprof. Here's my dilemma: if I compile with the same optimization settings I use for my release build, pretty much everything gets inlined, and gprof tells me, unhelpfully, that 90% of my time is spent in a core routine, where everything was inlined. On the oth...
My flex application, processes user request and makes an HTTP request to the backend, for data processing, and renders the data on the UI. (typical HTTP request-response based application). I need to do a performance analysis on the whole system, in order to identify and resolve bottlenecks, hence need to measure the time-split of the w...
Hi, We're trying to measure performance of our system, which is a .NET 3.5 application that uses WCF calls. Problem is until now, we weren't able to profile the methods inside these calls. A winforms client application was coded to test our system. We tried using ANTS 4 Profiler and VS2008 built-in Performance Analyzer, but we only got...
Anyone know how to profile a Google App Engine for java app? Preferably I'd like to use the build in netbeans profiler, but that has an error on startup when I try to use it. Here is the error when I try to profile with netbeans 6.8: runserver-profile: [java] Error occurred during initialization of VM [java] Could not find a...
I have a widget that is inserted on numerous Web pages. It's composed of some JavaScript that loads an HTML document from my server (as JSONP) which is then inserted into a dynamically created <iframe> on the page where the widget is deployed. I use Clicky for analytics/tracking to measure the number of pageviews that my widget's host p...
I would like to run profiling code against some services running in testing and production. My plan is to use PostSharp to implement a class that looks like public class TimerAttribute : OnMethodBoundaryAspect { //some data members //... public override void OnEntry(MethodExecutionEventArgs eventArgs) ...
I have a few scripts that use jQuery, and I think I have a memory leak in one of them. How one could profile and find what parts of the scripts that I have are using the most memory/CPU? Thanks ...
Hi, I'm developing an application in C++ on Windows XP, using Eclipse as my IDE, and a Makefile-based build system (with custom tools to generate the Makefiles). In addition, I'm using LZZ, which allows me to write a single file, which then gets split into a header and an implementation file. I'm using TDM's port of GCC 4. What tools o...
Do you have a nice class you use for measuring time a PHP script loads certain blocks of code? Would you care to share what YOU use? ...
I've been meaning to do a little bit of brushing up on my knowledge of statistics. One area where it seems like statistics would be helpful is in profiling code. I say this because it seems like profiling almost always involves me trying to pull some information from a large amount of data. Are there any subjects in statistics that I ...
Hi! is there a way to profile cache misses in an iphone application? http://developer.apple.com/iphone/library/documentation/DeveloperTools/Conceptual/SharkUserGuide/GettingStartedwithShark/GettingStartedwithShark.html tells that there is a 'Hardware Measurements' Profiling mode in Shark which enables L2 cache miss profiling - however...
I am trying to profile a specific page of my ASP.NET site to optimize memory usage, but the nature of .NET as a Garbage Collected language is making it tough to get a true picture of what how memory is used and released in the program. Is there a perfmon counter or other method for profiling that will allow me to see not only how much m...
In the past I've used performance profiling tools such as nprof, Equatec profiler and Yourkit profiler to identify and remove/reduce performance bottlenecks in code mostly running in one thread (serialized execution). Nowadays I write a lot of multi-threaded code which can be slowed down by lock contention; what tools and tricks can be u...
I am working on performance tuning a web service. I am using a trial of JetBrains to profile the application. When I import a file, 15% of the execution time is going toward GetCurrentContextInfo, here's the signature: Void System.ComponentModel.LicenseManager.LicenseInteropHelper.GetCurrentContextInfo(Int32 &, IntPtr &, RuntimeTypeHa...
I am somewhat familiar with the CUDA visual profiler and the occupancy spreadsheet, although I am probably not leveraging them as well as I could. Profiling & optimizing CUDA code is not like profiling & optimizing code that runs on a CPU. So I am hoping to learn from your experiences about how to get the most out of my code. There was...
I need some means of recording the performance of an application on a Linux machine. I won't have an IDE. Ideally, I need an app that will attach to a process and log periodic snapshots of: memory usage number of threads CPU usage Any ideas? ...
