Hi Json,
With V2 of your patch here are the results for the ebizzy run on
3.11-rc1 + patch on a 1 socket, 16 core powerpc machine. Each ebizzy
run was for 30 seconds.
Number_of_threads %improvement_with_patch
4 8.63
8 1.29
12 9.98
16 20.46
Let me know if you want me to profile any of these runs for specific
statistics.
Regards
Preeti U Murthy
