Hello,

to give a benchmark, it takes around 8h to run memcheck on the whole test-suite, which means a slow-down factor of approximately 50x. This is with -O3 though, which may hide or produce bogus uninitialized value errors under certain (but rare) circumstances (according to the valgrind documentation). Since its diagnostics concerning memory errors seems pretty much exhaustive (it is e.g. comparable to clang's address + memory + leak sanitizer), I am wondering what Visual Studio is (thinking it is) doing? Is it turning off optimization maybe? Or is it doing something in the direction of thread-safety?

Is it possible to switch optimization levels, debug symbol generation and sanitizing code instrumentation separately from each other in the studio? If yes, one can maybe find a viable compromise for these settings between running time and error sensitivity depending on what exactly one is expecting.

Hi Francois,

    in Release mode, it should be in the neighborhood of 10 minutes.  I see you're running it in Debug mode, though; it adds all kinds of additional run-time checks, so it will take way more. I'm not sure how much exactly, since I haven't run it in a long time...

Hi all,

For how long is the test suite support to run.... ballpark figure. I've got a pretty powerful 8-core machine with an SSD. I kicked off the test suite yesterday and it's been running for almost 24hours. I can see one core is being utilised at 100%. What runtime do you guys have? Does the log_level parameter affect the runtime significantly?

Here are some Process Hacker screenshots of my currently running process:

thanks
