Yes. This makes me wonder if I could speed up our builds by 2x by whitelisting the source repository folder. If it's at all possible (and company policy allows for it)...
One thing that deeply frustrates me is that I simply don't know which things are slowed down by Defender. I can add my source repos to some "exclude folder" list deep in the Defender settings, but I've yet to figure out whether that actually does something, whether I'm doing it right, whether I should whitelist processes instead of folders or both, I have no idea.
If anyone here knows how to actually see which files Defender scans / slows down, then that would be awesome. Right now it's a black box and it feels like I'm doing it wrong, and it's easily the thing I dislike the most about developing on Windows.
The bit about Windows Defender being hooked into every process is also infuriating. We pay a high price for malware existing even if we're never hit by it.
