Performance features
"Big Result" security trap threshold (experimental)
When processing a very lot of data, you may stuck your db connection and faildown your db server on low powered hostings. If this case occurs, it might be difficult to fix the query as having no more access to the configuration panel of the Dashboard block. If you ae not a Moodle dtabase expert and knows how to rip off the damaged block instance configuration, this settign could prevent big results from being otput without paging.
F.e , setting 300 as threshold will force any query ouptuting more than 300 lines of result to enter the paged display mode.
