get_num_queries vs. SAVEQUERIES

Hi,

I’m running some optimisation tests and noticed that the output of these two tools differ in terms of elapsed time.

<?php echo get_num_queries(); ?> queries in <?php timer_stop(1); ?>
gives the result ’27 queries in .497 seconds’

Whereas when I add up the times from each query in the SAVEQUERIES array, the total comes to 0.056529522

Obviously vastly different numbers – can anyone elaborate on why this would be the case?

Thanks,
Taylor
