/**
* Benchmarking
*
* Benchmark code to test the speed to the ADODB library with different databases.
* This is a simplistic benchmark to be used as the basis for further testing.
* It should not be used as proof of the superiority of one database over the other.
*
* This file is part of ADOdb, a Database Abstraction Layer library for PHP.
