What i wonder is if the following are alose read ahead: - The default icon theme is also read ahead? - The GTK parts so that for example gnome-panel is open faster or any gtk using app - Are the most used user applications (Specially nautilus and firefox) fully read ahead so that they start FAST (will greatly improve user experience) I hope the performance of readahead can go up a bit more (25%?) Anyway good numbers so far! Keep up posted if you want. -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
