$lockManager = LockManagerGroup::singleton( wfWikiID() )->get( $wgWBRepoSettings['dispatchingLockManager'] ); $t0 = microtime( true ); for ( $i = 0; $i < 500; $i++ ) { $lockManager->lock( [ 'T205865-test-lock' ] )->isOK(); $lockManager->unlock( [ 'T205865-test-lock' ] )->isOK(); } echo microtime( true ) - $t0;mwmaint1001: 73.30463886261
mwmaint2001: 0.64075589179993
Reversing this experiment now that we have switched back I see:
mwmaint 1001: 1.4454369544983 mwmaint 2001: 3.811069011688
