Details

ALF_PRELOAD_LINKS

As for ALF_LINK_LOCK, this flag is a necessity for high-traffic wikis. (This option was introduced in 1.5.0 and has no effect since 1.18.0)

Beispiel

To reduce lock contention, at the expense of introducing occasional inconsistencies, set:

$wgAntiLockFlags = ALF_NO_LINK_LOCK | ALF_NO_BLOCK_LOCK;
