bperf's Issues

Need to reset profile interval to 1ms after relogging is complete

Add symbolization process and info

Add infinite cpu detection for "services"

Including those that are CLR ones, or Chakra/ChakraCore ones

Ctrl+C waits for entire session to complete before yielding

We need to instead immediately terminate (or after X seconds) terminate the logging session.

Add CSwitch analysis

LoadLibrary to find NtSetSystemInformation is happening in every relog

Add hot ip analysis

Add support for a "stamping" event

Lets us correlate to SampledProfile to high level requests

Cannot compile

The solution references outdated libraries. Please make it compile with VS 2022.

Can you provide a binary release of the project? If I would like to try things out that would be a big help.

Build bug: 'ICorProfilerCallback8': base class undefined

I cloned the repo and couldn't compile. The first error was the title (and another million followed, as is usually the case with these errors).

Now 'ICorProfilerCallback8' is only available in .net v4.7+, but for some reason, although I have .net v4.7+ installed, it can't find that base class.
The reason turned out to be that the project was including the profiling api headers of .net 4.6.1, because in my vs2017 cmd prompt, the environment variable 'NETFXSDKDir' was set to 'C:\Program Files (x86)\Windows Kits\NETFXSDK\4.6.1'.
(this may be related to the following bug, but I'm not sure)

Anyway, for me, opening vs2017 dev cmd and running:
set NETFXSDKDir=C:\Program Files (x86)\Windows Kits\NETFXSDK\4.7\
and compiling from there, fixed that.

It might be a good idea to add this to the build instructions.
