My i7-3770 (also 3 years old and the 3770 is not the fastest i7) takes 12 seconds from boot menu to login screen, and under 20 from login to KDE (autostarting 6 virtual desktops, a couple of Konsoles, a Qbittorrent instance and Evolution, but no browser). Even a small SSD is a worthwhile investment. poc _______________________________________________ kde mailing list -- kde@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to kde-leave@xxxxxxxxxxxxxxxxxxxxxxx
