Do you have lots of debuginfo packages installed or is the DEBUGINFOD_URLS set? See https://fedoraproject.org/wiki/Debuginfod valgrind is fairly slow parsing all the DWARF information. But will happily use debuginfod to fetch more or use all debuginfo packages installed for any library you have installed. In your case it might be help unsetting DEBUGINFOD_URLS and looking trough the list of installed debuginfo packages and uninstall some (if I read your log it is probably libstdc++-debuginfo that takes a lot of time to parse.
