I agree for the PR template. As for improving cppcheck speed I did some tests but I don't think there's that much improvement; moreover you cannot control checks granularity that much. Like if you want code style checks but don't want performance checks, you can't because those are connected, for some reason. That been said, on my PC it takes ~2m 15s to run with all checks. If all the warnings checks are disabled and so only errors are on, it takes ~1:55.
