According to Julian Elischer: > for a real laugh, try timing deletion of a large directory hierarchy.. > > enjoy.. I've tried the patches and I must say I'm impressed. Softupdates are faster than async for some things and much faster for others. "cp -pr" was just a little bit faster but bootstrapping egcs-980205 using "async,noatime" was about between 38 and 45 minutes. Using "soft-updates,noatime" gave me: 1478.805u 118.119s 27:39.27 96.2% 1627+2376k 7767+2440io 1019pf+0w I can't wait for a "make world" gain (waiting for the big CTM delta to arrive)...
