Java Profiling, Performance Tuning and Memory Profiling exercises
by Kagee in Network & Servers

I am about to conduct a workshop profiling, performance tuning, memory profiling, memory leak detection etc. of java applications using JProfiler and Eclipse Tptp.
I need a set of exercises that I could offer to participants where they can:
Use the tool to to profile the discover the problem: bottleneck, memory leak, suboptimal code etc. I am sure there is plenty experience and real-


Remote Profiling with D7 (NOT memory profiling, but timing…)
by jbcrail in Programming Languages

We have one machine in-house that is 20 times slower starting our Delphi 7 app than any other machine.


We would like to get a performance profile (not memory profile) to locate where it's spending its time.


AQTime, which we own, we've discovered doesn't do remote profiling.


We'd prefer not to take the time to build up an entire D7 IDE development environmen


profiling with g++
by Luciano Campos in Web Design

How to profile c++ code to get the call times and cost time of each line of the code, just as the profile tool
in Matlab does?


I tried to use things like -fprofile-arcs, but it only generates a code coverage report, in which call times can be found, but cost time cannot.


Can anybody help out? Regards.

Profiling ASP.NET
by Munir in Programming Languages

I'd like to profile sections of asp.net code to be able to objectively compare alternate approaches based on some real numbers.


A good example is: I'd like to see an instruction trace for for what happens when a repeater is rendered vs (blech - the following is NOT my idea) building markup in a concatenated string or stringbuilder and emitting to the browser. I'd also like to be ab

I am building a site using WebFormsMvp and Entity Framework 4.


The site is a bit slow and when i profile in dotTrace these three methods take 75% of the time. (My first method takes about 3%)

Bugzilla profiling
by Gerle in Programming Languages

I serached for 3 days now, and i didnt find the right solution.


I am trying to make 3 profiles for one product in Bugzilla 4.2:


Reporter - that is, client, who would be able to file new bug and make some changes, but not all - he won't be able to change through all statuses, to assign bug to someone - just to report bug
Developer - he would be able to change everything

Remotely profiling a JVM
by phokus in Programming Languages

I need to remotely profile a JVM for CPU Usage, IO stats and File descriptor/handler count and support both *NIX and windows platforms while doing so. I tried using the SIGAR API, which abstracts the platforms very well using an underlying native code implementation, but it does not support remote profiling. Is there an alternative API which can do this? Alternatively, is it feasible to extend


Profiling Library for .NET
by iamwiz82 in Programming Languages

Edit: I'm NOT asking for a way to implement a profiling library, I'm asking if there's one (preferably free) out there.


Although there are a lot of commercial and free profilers for the .NET platform they all analyses (better or worse) your application code in a way that let's you see what method call or even line is consuming a lot of resource.


While that might be usefu


C++ Profiling: KiFastSystemCallRet
by Milander in Programming Languages

I searched for this after seeing it's the top rated item when profiling using Very Sleepy, and it seems everyone gets the answer "it's a system function, ignore it". But Sleepy's hint for the function says:


Hint: KiFastSystemCallRet often means
the thread was waiting for something
else to finish. Possible causes
might be disk I/O, waiting for an

C++ profiling and optimization
by golazo in Programming Languages

I have some issues with performance of my application. I found this answer on Stackoverflow:
http://stackoverflow.com/a/378024/5363


which I like. One bit I don't really understand is what is the relation between code optimization and profiling. Because obviously one wants to profile optimized code, but at the same time a lot of information is lost during optimizations. So is it
