I've been using this for a few months now, and it's targeted to replace mlocate in Fedora in the next Fedora release: <a href="https://fedoraproject.org/wiki/Changes/Plocate_as_the_default_locate_implementation" rel="nofollow">https://fedoraproject.org/wiki/Changes/Plocate_as_the_defaul...</a> . I've been pretty happy with it, but I'll also add I never had any problems with mlocate.
