You can check with the profiler Plugin if there is something slowing your server down.

You should use newer mysql versions for asynchron mysql querys.

To speed this query up, write it like this:

PHP Code:

UPDATE `cars` SET `Spawned`='%d' WHERE `ID`='%d' LIMIT 1 


But maybe there are some other Callbacks like

PHP Code:

OnPlayerUpdate 


or timer, which slows your server.
