Missing file when running the benchmark

[jLynx]

When I attempt to run the benchmark I get this error

[27-Jun-2017 10:04:22 Pacific/Auckland] PHP Warning:  require_once(Benchmark/Profiler.php): failed to open stream: No such file or directory in C:\WebServer\something\tests\benchmark.php on line 3
[27-Jun-2017 10:04:22 Pacific/Auckland] PHP Fatal error:  require_once(): Failed opening required 'Benchmark/Profiler.php' (include_path='.;C:\php\pear') in C:\WebServer\something\tests\benchmark.php on line 3

I cant seem to find that file on the repo at all, can you help me out here?
