They turned off write caching on IDE drives for one thing. My buildworld time log shows the difference. For example, buildworld -j8 1649.700u 679.762s 41:23.96 93.7% 1283+1449k 45479+3468io 1642pf+0w 1653.885u 677.372s 41:17.73 94.0% 1285+1449k 46791+3418io 1609pf+0w buildworld -j6 1601.699u 657.196s 29:00.09 129.8% 1314+1472k 43718+3411io 3248pf+0w 1606.729u 640.580s 29:00.13 129.1% 1321+1483k 43964+3408io 3284pf+0w buildworld -j8 1598.496u 642.897s 28:55.45 129.1% 1322+1483k 44354+3431io 3289pf+0w The first two were when write caching was turned off and the last three were after it was turned back on as a default.
