BlockProtection - automatic per-block protection

[donvdp]

Is anyone using this plugin on a large server (150+ players)?? if so. does this plugin cause lagg over time ??

Im wondering this because:

if a player breakes a block then the server has to run through a database of all the protected blocks.... im betting if the database is large eneugh and the amount of players on the server is high eneugh this will cause preformance issues ??
