The Internet Super Hero blog has posted 59 statistics they've generated while they were sting the latest versions of the mysqlnd (native driver) in PHP:

59 - that is the number of statistics collected by mysqlnd. When I started writing this blog post, I hoped it would be easy going describing them. But it wasn't. Some ten days ago, we've had 51 statistics and near zero tests for them. Now we have 59 statistics. And, in a certain way, every figure is a tuning screw in the hand of one who knows what they do.

The list of stats presented include functionality for:

• buffered_sets, ps_buffered_sets
• rows_buffered_from_client_normal, rows_buffered_from_client_ps
• rows_fetched_from_client_ps_buffered
• unbuffered_sets, ps_unbuffered_sets
• rows_fetched_from_client_ps_unbuffered
• flushed_normal_sets, flushed_ps_sets

Check out the rest of the post for the numbers and results (as well as some images showing the difference between buffered and unbuffered results).
