Good evening,

Does anyone know how much of a performance hit turning stats_block_level and
stats_row_level on will incur? Do both need to be on to gather cache
related statistics? I know the annotated_conf_80 document states to only
turn them on for debug but if they're not that performance intensive I
cannot see the harm.

Thank you,
Tim McElroy
