I have 2.4.5 here: make -j6, libtool real 4m53.924s user 11m4.323s sys 0m54.880s make -j6, dolt real 1m58.653s user 6m20.523s sys 0m28.920s -- Lucas De Marchi _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
