profiler

I am aware of Valgrind, but it just detects memory management issues. What I am searching is a tool that gives me an overview, which parts of my program do consume how much memory. A graphical representation with e.g. a tree map (as KCachegrind does for Callgrind) would be cool. I am working on a Linux machine, so windows tools will not help me very much. ismail Use massif , which is part of the Valgrind tools. massif-visualizer can help you graph the data or you can just use the ms_print command. Paolo M Try out the heap profiler delivered with gperftools , by Google. I've always built it

I would like to know if it is possible to get a profile from R -Code in a way that is similar to matlab 's Profiler. That is, to get to know which line numbers are the one's that are especially slow. What I acchieved so far is somehow not satisfactory. I used Rprof to make me a profile file. Using summaryRprof I get something like the following: $by.self self.time self.pct total.time total.pct [.data.frame 0.72 10.1 1.84 25.8 inherits 0.50 7.0 1.10 15.4 data.frame 0.48 6.7 4.86 68.3 unique.default 0.44 6.2 0.48 6.7 deparse 0.36 5.1 1.18 16.6 rbind 0.30 4.2 2.22 31.2 match 0.28 3.9 1.38 19.4 [<

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 to remain in place and obstruct garbage collection. Are there any good tools for profiling the memory usage associated with various native data primitives, blessed hash reference objects, etc. within a Perl program? What do you use for tracking down memory leaks? I

We are using JetBrains ' dotTrace . What other profiling tools can be recommended that are better for profiling C# Windows Forms applications? McKenzieG1 No. I have tried pretty much every .NET profiler on the market (ANTS, vTune, OptimizeIt, DevPartner, YourKit), and in my opinion dotTrace is the best of the lot. It is one of only two profilers I have used (the other being YourKit) that has low enough overhead to handle a highly CPU-intensive application. If and only if your application is relatively light, I could recommend ANTS Profiler . Its line-by-line stats are sometimes quite useful,
