On a machine that I upgraded from FC6, I noticed the compiles were slow, and that is because ccache was not installed as a part of the upgrade. But on a fresh F7, whoa, watch out. Major improvement. The F7 release announced a lot of changes that I never use (Xen). For my (free) money, ccache was the biggest improvement I've seen in Fedora 7. Only downside I can see is that the ccache seems to be stashed in a hidden user home directory. After building some really programs like firefox or gcc, that is one monsterously big hidden directory. Since I did not know ccache was even installed on that system, it took a little back-tracking to figure out why the backup of my home directory was failing because it exhausted the space on the backup device. Small price to pay for such massive acceleration, though. -- Paul E. Johnson Professor, Political Science 1541 Lilac Lane, Room 504 University of Kansas
