Includes cache aware roofline analysis. CPU Profiling gprof: reported not to work taking an hour to load on our large binary. Application Performance Management. One drawback is the evaluations of time spent are statistical approximations rather than actual time. For more powerful commands, please refer to the pprof help output and the google-perftools documentation. Profiles everything running on the Linux system, including hard-to-profile programs such as interrupt handlers and the kernel itself.
CPU Profiling Tools on Linux
gperftools (originally Google Performance Tools) The fastest malloc we've The heap checker is only available on Linux at this time; see INSTALL for. Google Perf Tools is now hosted at Perf Tools is a collection of a high-performance multi-threaded malloc() implementation, plus some.
How to profile Chromium on Linux. See Profiling google-perftools code is enabled when the use_allocator gn variable is set to tcmalloc (currently the default).
There are other useful userspace tools available though.
Linux Profiling tools and techniques
Learn more. Collects data on processes blocking, context switches, and execution time. The perf record command collects samples and generates an output file called perf. Sampling Sampling measures applications without inserting any modifications.

It is better to switch to more modern Linux perf profiler (tutorial from its test around seconds, so cpuprofiler from google-perftools can't do.
Sandboxed renderer subprocesses will fail to write out heap profiling dumps. For example:. Some of the libraries and functionality have been ported to other Unix systems and Windows.
Sampling profilers record the executed instruction when the operating system interrupts the CPU at regular intervals to execute process switches, and correlates the recorded execution points with the routines and source code during the linking process.
Sampling profilers causes little overhead to the application run process, and they work well on small and often-called routines.
