//Disabling the Directory Monitoring will use a brute force scanning method to evaluate which files in the project have been changed, and is much slower EditorPrefs.SetBool("DirectoryMonitoring", false); Debug.Log("Is Directory Monitoring Enabled? - " + AssetDatabase.IsDirectoryMonitoringEnabled());

Benchmark(BenchmarkCount); BenchmarkCount++;

EditorPrefs.SetBool("DirectoryMonitoring", true); Debug.Log("Is Directory Monitoring Enabled? - " + AssetDatabase.IsDirectoryMonitoringEnabled()); Benchmark(BenchmarkCount); }
