True, I've noticed this meanwhile. Are there any recommendations for
this setting where the limit is as large as possible while staying
within a reasonable performance? Of course, this is highly subjective,
but what's the magnitude here? Will a limit of 1,024,000 typically
increase the query time by the factor 1,000 too?
