I have attached the results of the benchmark for people to review. I am not convinced of the validity of the benchmark because the following message repeatedly showed up in dmesg: do_page_fault() pid=22449 command='lat_sig' type=15 address=0x40019000 vm_start = 0x40019000, vm_end = 0x4001a000 YZrvWESTHLNXBCVMcbcbcbcbOGFRQPDI PSW: 00000000000001100000000000001111 Not tainted r00-03 0000000000000000 fffffffffffff000 0000000000011f3b 0000000040019000 r04-07 00000000bff00410 00000000bff001c8 0000000000027a32 0000000000000003 r08-11 0000000000027a72 0000000000000000 00000000000cea08 00000000000cf148 r12-15 0000000000000000 00000000000cafe8 00000000ffffffff 0000000000000000 r16-19 0000000000000000 00000000000b9e9c 0000000000000000 0000000000000001 r20-23 000000000000004e 00000000400cf460 0000000000000000 0000000000000008 r24-27 0000000000000000 0000000000000000 0000000000027b4c 0000000000027870 r28-31 0000000000000000 0000000000000000 00000000bff00500 00000000400cf46b sr0-3 00000000002bcf00 00000000002bcf00 0000000000000000 00000000002bcf00 sr4-7 00000000002bcf00 00000000002bcf00 00000000002bcf00 00000000002bcf00 but I wanted to throw the results out for discussion.
