I see a decrease in total time (so an improvement in performance) going from 37.3 to 35.2 seconds with the pread patch on Linux x86-64. Note that both my testing on Linux and Mac OS X was done on dual core processors (Athlon 3800+ XP on Linux and Intel Core 2 Duo 2.16GHz on an iMac). Git is only single threaded and thus uses only core, but the system can use the other core. The minor page faults also decreased from 734866 to 370690.
