One of the nice things about the PerfView repository is that it has the latest version of the code. Thus if you need a bug-fix or some recently added feature, you can get this by simply building the repository.It turns out that one of the new features of PerfView (not present in ...
onurg September 19, 2016 Wow, great news! Wu Shuai September 19, 2016 Thank you Vance to provide this wonderful tool. Alois Kraus September 19, 2016 The source code for the very cool PerfView tools is a great addition. Thanks Vance!English...
I am happy to announce, that the PerfView source code is now open source as a GitHub repository. It is available at https://github.com/Microsoft/perfview The readme associated with the GitHub repository has getting started information (how to fetch the repository, how to build, test and ...

Performance analysis tools based on Linux perf_events (aka perf) and ftrace - hashbrowncipher/perf-tools
perf-tools A miscellaneous collection of in-development and unsupported performance analysis tools for Linux ftrace and perf_events (aka the "perf" command). Both ftrace and perf are core Linux tracing tools, included in the kernel source. Your system probably has ftrace already, and perf is of...
If the overhead is a problem, these tools can be improved. If a tool doesn't already, it could be rewritten in C to use perf_events_open() and mmap() for the trace buffer. It could also implement frequency counts in C, and operate on mmap() directly, rather than using awk/Perl/...
