Of all the functions in `git_config*()` family, `git_config()` has the most invocations in the whole code base. Each `git_config()` invocation causes config file rereads which can be avoided using the config-set API. Use the config-set API to rewrite `git_config()` to use the config caching layer to avoid config file rereads on each invocation during a git process lifetime. First invocation constructs the cache, and after that for each successive invocation, `git_config()` feeds values from the config cache instead of rereading the configuration files.
