File be/src/benchmarks/string-compare-benchmark.cc:

PS2, Line 202:  suite.AddBenchmark("Original", 
TestStringCompare<StringCompare1>, &data);
             :   suite.AddBenchmark("Simplified, broken", 
TestStringCompare<StringCompare2>, &data);
             :   suite.AddBenchmark("Simplified, fixed, strncmp",
             :       TestStringCompare<StringCompare3<char, strncmp>>, &data);
             :   suite.AddBenchmark("Simplified, fixed, memcmp",
             :       TestStringCompare<StringCompare3<void, memcmp>>, &data);
which of these measure the performance of the new implementation which always 
uses memcmp()?
