Details
[edit]Whether site_stats table should have multiple rows.
If set to true, in each update, one of ten rows gets updated at random to reduce lock wait time in wikis that have lots of concurrent edits.
It should be set to true in really large wikis with big flow of edits,
Otherwise it can cause inaccuracy in data.
