how to find out why this solution is so slow. Are there any commands that tell me where most of the computation-time is spend so I know which part of my haskell-program is slow? Precisely! GHC provides many excellent tools, including: runtime statistics time profiling heap profiling thread analysis core analysis. comparative benchmarking GC tuning … Read more
Unfortunately, there are not measurement tools for retrieving the execution time of built-in functions. This has already been commented by @Rubén. So I thought of about the workarounds. How about the following workaround? Flow : Import a value to a cell. The value is anything good, because this is used as a trigger. Please do … Read more
The debugger in Eclipse can show you all the instances of a class, so I looked around Eclipse’s sources. Eclipse uses the Java Debug Wire Protocol, which allows you (since Java 6) to look up all the instances of the requested class. If you want to go down this path, grab a copy of Eclipse … Read more
Take a look at Java Mission Control in conjunction with Flight Recorder. Starting with the release of Oracle JDK 7 Update 40 (7u40), Java Mission Control is bundled with the HotSpot JVM, so it is highly integrated and purports to have small effects on run-time performance. I have only just started looking at it, and … Read more

First some general remarks: In general, what you are doing is mostly an exercise in futility and is the reverse of how most people would probably go about performance analysis. The first point to make is that the peak value you are quoting is for strictly for floating point multiply-add instructions (FMAD), which count as … Read more

It looks like they have changed their user interface since Pavel’s instructions were posted. Here are the instructions I wrote up for my team. They replace steps 4-8 in Pavel’s post. To profile an ASP.NET application using EQATEC, just select the application’s bin folder in the App Path setting. Then, click the Build button at … Read more
I asked the same question not too long ago I’ve downloaded and tried AQtime. It does seem comprehensive, but it is not an easy to use tool and is VERY expensive for an individual programmer (i.e. $600 US). I loved the fact that it was non-invasive (did not change your code), and that it could … Read more
Analysing memory leak using visualvm is not that easy. It has a tool/plugin called ‘sampler’. This can be used to sample memory or cpu. You can take snapshot at regular interval and look for possible leaks. Here is some details on how to use it- Obtained from quick search More effective way will be to … Read more
