I did a run and here's what I got: 32bit: atoi_test: 2.7353607652 [s] {checksum: 3b6f0e0} strtol_test: 2.5913341972 [s] {checksum: 3b6f0e0} spirit_int_test: 1.2209585612 [s] {checksum: 3b6f0e0} atof_test: 2.7674816420 [s] {checksum: 84a4f7d} strtod_test: 3.0302511938 [s] {checksum: 84a4f7d} spirit_double_test: 0.8215847269 [s] {checksum: 84a4f7d} /////////////////////////////////////////////////////////////////////////// 64bit: atoi_test: 2.5954563140 [s] {checksum: ea987f7a} strtol_test: 2.4382622754 [s] {checksum: ea987f7a} spirit_int_test: 1.0699516219 [s] {checksum: ea987f7a} atof_test: 2.7788751173 [s] {checksum: 84a4f7d} strtod_test: 3.0187541826 [s] {checksum: 84a4f7d} spirit_double_test: 0.8012355484 [s] {checksum: 84a4f7d} Check it out.
