If you think perf is impressive you should try Intel vTune. Has support for finding hot mutexes, all perf counters, and even generates neat graphs that show diagrams of synchronization points between multiple threads.

Second that. It is amazing for C and C++ code - but does not work well on VMs such as AWS or with Java code.

  ... I believe I was the first person to run vTune from an AWS EC2 guest. I'll share details when I can. :)

Are there affordable options for non-enterprise customers? I use it at work, but we buy bulk licenses and I was under the impression that licenses start at several thousands per seat.

Hi Hendzen, I found in one of your previous comments that you have set up your emacs to have full support for c++ projects, like auto-completion and reference following and similar. I have been using Emacs for a few years now, for js/python/html/C/C++/anything else and have just started working on a larger C++ project where intelligent auto completion and navigation would help a lot. Would you mind providing some more details on how you got it set up, maybe share your init.el file? It is a Cmake project, uses ninja as a generator. Thanks!

  I'm writing less C++ than I used to recently, but here's the basic setup I use: 1) Emacs prelude w/ helm enabled everywhere -https://github.com/bbatsov/prelude https://github.com/bbatsov/prelude 2) Irony-mode for auto completion. Since you're using Cmake, you can just add CMAKE_EXPORT_COMPILE_COMMANDS to your invocation to output the needed metadata for completion to work. - https://github.com/Sarcasm/irony-mode https://github.com/Sarcasm/irony-mode 3) helm-flycheck for syntax checking https://github.com/yasuyk/helm-flycheck https://github.com/yasuyk/helm-flycheck 4) For jump to definition I generally just use helm-ag (grep) , I never actually got this working to my satisfaction despite trying a few things like rtags (slow, unstable) and clang-ctags (promising but annoying to set up at the time). 5) For formatting I usually just enable clang-format on save w/ something like this (requires clang-format mode installed): (add-hook 'c++-mode-hook (lambda () (add-hook 'before-save-hook #'clang-format-buffer nil t)))
